The best conditions to store your car

Are you thinking about storing your car away for winter – or maybe longer?

Indoor car storage is a safer bet than the bleak British outdoors, but there are still temperature and humidity elements to think about when storing your car indoors.

In today’s blog we’re looking at the optimal conditions to keep your car protected whilst in storage – Here’s what we’ll be covering:

  • Temperature and light – Does it matter if it’s too hot or too cold?
  • How does humidity affect your car?
  • What is the ideal humidity and temperature for car storage?
  • How to monitor and control the conditions in your storage unit

Temperature and light – Does it matter if it’s too hot or too cold?


It’s tempting to store your car outside through summer when it’s sunny and mostly dry but sun damage is the first problem you may encounter when storing outside, or even indoors if your garage lets in a lot of light

UV rays can cause paintwork to fade over time and can also damage interiors too. Upholstery and trims become faded and leather becomes discoloured and is prone to cracking.

Hot temperatures

Heat from the sun or installed heating turned up too high can cause warping of components, cracked paintwork and also invite pesky critters to nest in hidden areas, away from the cold (who have a tendency to nibble at wires and upholstery)

Cold temperatures

When the storage environment is too cold moisture and condensation creep in, leading to a multitude of humidity problems which we talk about below. It can also cause freezing and damage to perishable components such as rubber seals and pipes.

How does humidity affect your car?

Too humid or not humid enough? Both can and will cause problems.

When storing your car at home, a ‘normal’ garage may seem a safe place to do so but with little insulation, it’s easy for condensation to form, resulting in an environment too humid for your car.

Humidity can also increase when you drive your vehicle in damp conditions, or after a much needed trip to the car wash – The moisture retained on your car will transfer to the garage, all of which affects humidity levels

So, how does too much moisture affect your car?

  • High humidity can accelerate the rusting process, leading to corrosion of bodywork
  • Rust acceleration may also cause mechanical components to corrode
  • Interior mould growth on upholstery

How about not enough moisture? This can also cause problems, including:

  • Cracking to leather and vinyl elements in your car such as seats or interior trims
  • Warping and cracking to wooden components
  • Seals can perish and crack

If the vehicle you’re storing is a classic or a rare model, it may be difficult or costly to source new components, so you want to ensure you’re doing everything you can to preserve each tiny component of your car.

What is the ideal humidity and temperature for car storage?


18℃ to 20℃ – The ideal temperature to store your car. Much lower than 18℃ and you risk an increase in moisture which will lead to humidity increase. Higher that 20℃ and you increase the risk of heat damage to seals, hoses and paintwork


55% – 60% relative humidity (RH) – Less than 55% you increase the risk of drying cracking of paintwork, seals, trims and hoses. Above 60% humidity risks the increase of possible mould and rust.

Studies show a huge increase in rust acceleration once humidity levels move above 60%

How do you monitor and control the conditions in your storage unit?

At classicwise our purpose built unit is kitted out with moisture meters and thermometers throughout the unit to continuously monitor the humidity and temperature of the facility.

We utilise a range of dehumidifiers and regulate air circulation via fans that create constant air circulation.

The building is also insulated in a way that regulates the temperature to a constant level throughout the year, no matter what the weather outside.

We do this to ensure the preservation of your car whilst stored with us. However if you’re storing at home or thinking of a self store facility, you’re unlikely to have the same kit as we do!

So if you do decide managed storage isn’t for you, we’d advise kitting your garage/unit out with thermometers and moisture meters at the very least, along with these tips:

  • Ensure your car is bone dry before storing. The best way to do this is by using a forced air blower to dry the exterior following a drive out or recent wash.
  • Get a good dehumidifier!
  • Allow for regular air circulation, taking care to keep an eye out for increased moisture from outside air
  • Don’t allow the storage area to get too hot – or too cold.

If that all sounds too much, bring your car to us and be safe in the knowledge that she’s stored in the best environment possible – or give us a ring for some advice. Our packages start from just £35+vat per week.

Preparing your car for storage

Preparing your car for storage

Are you thinking about putting your car into storage for a while?

Moisture, temperature, unwanted creepy crawlies – These are all things you’ll want to keep in mind before you store your pride and joy away for long periods of time.

Storing your car isn’t as easy as locking the doors and leaving her to sit quietly – but rest assured and read on, we’ve got a checklist for you.

This is the list we use when your vehicle comes to us for storage, adapted slightly for you to follow if you’re looking to store your car at home.

Whether storing in your garage or a rented unit, the checklist will help you preserve your car properly when storing for long periods.

To retain a vehicles value over long periods of time, it will be important to preserve paintwork, interior and small components alike.

Proper preservation will also save you money on parts that can be costly or difficult to source too – especially for anyone who has an older or fairly rare car or motorbike.

Let’s dive in.

1) Safe wash to remove dirt and road grime

Preparing your car for storage - Wash

Before you do anything else, make sure both the exterior and interior have a high quality safe wash.

This includes arches, underbody, paintwork and interior hoover. Ideally you’d dry the exterior with a forced air blower but we know not everyone has one of these hanging around in the garage so instead:

2) Leave your car uncovered for 48hrs (indoors) to ensure moisture evaporation

The last thing you want is to cover your vehicle or enclose it in your storage space too soon and humidity increase higher than recommended levels

If you do want to give your car the 5 star detailing treatment you can book in with the Classicwise detailing team, just pop over here to see our maintenance wash packages

3) The Damage Report

Preparing your car for storage - Damage Report

The purpose of the damage report is to check for scuffs, scratches and interior dirt.

You might just want peace of mind that no-one has caused any damage whilst in storage

Or you might come across something that will only get worse whilst stored away – in which case you can take it out to the relevant service provider to get fixed.

For example – You notice a particularly deep paint chip that might begin to rust without attention. Pre – storage is a good time to get that corrected, to preserve the paintwork.

4) Apply a battery conditioner

Preparing your car for storage - Battery Conditioner

Why is this important?

Lead-sulphur deposits build up inside car batteries when a vehicle is left unused for a long period, which reduces a battery’s ability to hold charge.

The battery conditioner increases the ability to hold charge by targeting these deposits, preserving the life of the battery and reducing the likelihood of needing a replacement when you’re ready to get back on the road.

A battery conditioner ranges from £40.00 – £100.00+ depending on the brand and retailer. We use the Ctek range

5) Levels checks – oil, coolant, fuel, tyre pressure

Preparing your car for storage - Battery Conditioner

We check and log all levels when your car enters our storage facility.

Oil, coolants,brake fluid, fuel and tyre pressures – mainly to ensure they meet manufacturers levels and ensure there are no issues when running the vehicle up to temperature or moving after long periods. If there appears to be any visible leaks we can identify and fix any problems quickly. Any changes in levels are logged in our system on a fault report.

It’s also useful to keep note that vitals are in good shape in case you decide on an impromptu Sunday drive out – the last thing you want is a flat tyre or low oil ruining your drive.

6) Get a good dust cover

Your cover should be soft and breathable to prevent moisture build up and rust. We use a soft fleece material with elasticated edges, they protect your car and look good too.

7) Last but not least. Routine checks

Prepped and ready to be stored safely, the final steps on your checklist are to keep an eye on your car.

Our storage team is on site daily to carry out battery checks and regular run up to temperature on each vehicle.

Depending on the individual needs of each car, we may also take vehicles out for a spin on a dry day to keep things ticking. This is all dependent on the car in question and always a favourite part of the job (who doesn’t love the opportunity to take a beautiful car for a spin)

There is a lot more to storage than just the car itself – the environment has to be right too of course. For more details about this head over to read our blog The best conditions to store your car here

What about when you’re ready to get back on the road?

Once you’re ready to take the vehicle out of storage, it’s good practice to check levels, tyre pressures, MOT/service dates and valet to make sure everything is in tip top shape.

Your Car Storage Questions Answered

classicwise storage image

Are you thinking about storing your car somewhere long term? Or maybe for a short period whilst you move house or are away for a while?

In this weeks blog we’ll answer some of the most frequently asked questions about storing your car safely, including:

  • Is car storage safe?
  • Can I store my car in a storage unit?
  • How much does car storage cost?
  • How do I prepare my car for storage?
  • Where should I store my car for winter?

Thinking about self-storage vs managed storage? Read on…

“Is car storage safe?”

The easy answer is yes, most of the time.

There are some things to think about though when it comes to where you store your car as some will be safer than others.

Many people store their own cars in a garage at home or sometimes in outside space on a driveway or under a partially covered area.

If you have space in a garage, this is always the safest option for storing cars at home. Not only can you lock the garage to keep it away from prying eyes but it’s also protected from weather damage too – because when we talk safety we’re not just talking theft but also preserving your paintwork, engine and interior too.

The value of your vehicle over time depends on many things such as weathered paintwork, sun damage on the interior and of course how well she runs mechanically.

If you plan to store your car for long periods of time, you’ll want to ensure all of the above elements are looked after whilst she’s stored away.

Speaking of which, the next question is about storage units, so let’s delve into what’s available and how each one might work best for you.

“Can I store my car in a storage unit?”

If you’re looking for somewhere away from home to store your car, a storage unit is a good idea – The question is, which kind of storage unit is best for you?

Rent a ‘self’ storage unit

The options here are to use a reputable firm who has on site security 24/7 or rent a local unit, which usually come with little to no onsite security leaving you to figure out which cameras, alarms and locking systems you need yourself.

Store your vehicle with a professional car storage facility

The benefits to storing your car in a professional car storage facility can far outweigh additional costs when it comes to the long term safety and care of your car. At Classicwise for example, we install comprehensive CCTV, alarms and security firms who notify us of disturbance on site, so we always know what’s happening with your car.

We also check vitals on the car before and during the cars stay with us, log any issues or changes onto a fault report, prep paintwork with a safe wash, install a battery conditioner, dust cover and regularly start and run the vehicle up to temp. All of this helps to protect and maintain the vehicle whilst she’s off the road.

Some of our cars need a run out on a dry day too, so if that’s something you feel your car would benefit from we’ll happily take her for a few mile spin around our local country lanes.

Now you know what you get with self vs managed car storage units, let’s talk winter – Does storing your car for winter differ from any other time?

“Where should I store my car for winter?”

If you have a car you don’t drive in winter months, it makes sense to store it somewhere dry and semi warm.

Leaving your car outside (even undercover) could cause the paintwork and mechanics to be affected by damp air and extreme cold spells – So we’d always advise storing your car somewhere you can monitor the moisture levels and temperature to ensure the preservation of your pride and joy.

The ideal conditions to preserve your car will be a humidity range of 55% – 60% and temperature range of 18℃ – 20℃

We use a range of moisture meters, thermometers, fan systems, insulation and dehumidifiers in our storage facilities.

How much does car storage cost?

It’s often thought that self-storage is a cheaper option than professionally managed storage, but this isn’t always true.

Large self storage companies offer initial discounts but for 100 sq ft with a reputable company who offers comprehensive security you can be looking anywhere from £40-£60 per week.

Units rented locally may be as cheap as £20 per week but come with very little security and can be damp or otherwise unfavourable environments to store a car safely.

With that in mind, it’s definitely worth talking to a specialist car storage company about their prices as they often have a much more in depth understanding of what your specific vehicle needs AND it might well be cheaper too.

Classicwise car storage starts from £35+VAT per week. For more info you can visit our long term and short term car storage pages. We’re always available to answer your questions about pricing and what we do to look after your vehicle.

By now you’ve probably made a decision on where to store your car, so what next?

How do I prepare my car for storage?

This is the checklist we use when a vehicle comes to us for storage, adapted slightly for you to follow at home. Whether storing in your garage or somewhere else, the checklist will help you preserve your car properly when storing it for long periods.

  • Safe wash to remove road grime – arches, underbody, paintwork, interior hoover, dried with forced air blower
  • Damage report – check for scuffs, scratches etc
  • Leave uncovered for 48hrs (indoors) – to ensure moisture evaporation
  • Apply a battery conditioner
  • Levels checks – oil, coolant, brake fluid, fuel and tyre pressures
  • Cover it – to prevent dust and moisture contamination
  • Routine checks – daily battery check, run up to temp regularly, run out if required.

The importance of climate-controlled storage for classic cars | Classicwise Cars

For classic car enthusiasts, their vehicles are more than just a mode of transportation; they are treasured investments, often with significant emotional and financial value. Preserving these classic beauties in pristine condition is paramount, and one of the key factors in achieving this is the storage environment. This post delves into the importance of climate-controlled storage for classic cars, exploring how it helps maintain their condition and value.

The Risks to Classic Cars in Non-Controlled Environments

Classic cars are particularly susceptible to environmental factors. Exposure to extreme temperatures, humidity, and other elements can lead to a range of issues:

  • Rust and Corrosion: High humidity levels can accelerate the rusting process, damaging the car’s body and engine components.
  • Paint Damage: Fluctuations in temperature and exposure to UV light can cause the paint to fade, crack, or peel.
  • Interior Deterioration: Leather, vinyl, and other materials used in car interiors are vulnerable to heat and moisture, leading to cracking, warping, and mould growth.
  • Mechanical Issues: Prolonged exposure to unsuitable conditions can lead to the deterioration of rubber seals, hoses, and other mechanical parts.

The Benefits of Climate-Controlled Storage

Climate-controlled storage facilities offer a stable environment, crucial for the preservation of classic cars:

  • Temperature Regulation: These facilities maintain a consistent temperature, preventing the damage caused by extreme heat or cold.
  • Humidity Control: By keeping humidity levels in check, climate-controlled storage helps prevent rust and corrosion.
  • Dust and Pest Control: These facilities are typically well-sealed, reducing the risk of dust accumulation and pest infestations that can damage the vehicle.
  • UV Light Protection: Indoor storage protects the car from harmful UV rays, preserving the paint and interior materials.

Additional Protective Measures in Climate-Controlled Facilities

Beyond temperature and humidity control, these facilities often offer additional protective measures:

  • Security Features: Enhanced security systems, including surveillance and restricted access, provide peace of mind.
  • Professional Maintenance: Some facilities offer regular maintenance checks and services to ensure the car remains in top condition.
  • Customisable Options: Owners can often choose specific conditions tailored to their vehicle’s needs.

Climate-Controlled Storage vs. Traditional Storage

While traditional garages or storage units may seem cost-effective, they lack the specialised environment needed for classic cars. The initial savings can be quickly offset by the costs of repairing damage caused by inadequate storage conditions.

The Role of Climate-Controlled Storage in Classic Car Valuation

The condition of a classic car significantly impacts its value. Cars stored in climate-controlled environments tend to appraise higher and are more sought after in the collector’s market. This aspect is crucial for owners who view their classic cars as investments.

Choosing the Right Climate-Controlled Storage Facility

When selecting a storage facility, consider the following:

  • Stability of Environment: Ensure the facility can maintain consistent temperature and humidity levels.
  • Security Measures: Look for facilities with robust security systems.
  • Accessibility: Consider how easily you can access your vehicle when needed.
  • Reputation and Reviews: Research the facility’s reputation and customer feedback.
