Will my classic car deteriorate if stored long term?

It’s a common question for those fortunate enough to find themselves as a classic car custodian – you work hard to own such a machine, but what will happen to your pride and joy while you are away funding it?

Undeniably, extended periods of slumber have a negative impact on classic cars, some more than others. However, this can be controlled with some prior planning, preparation and persistence…

 

Paintwork and chrome

Exposure to the elements can have several different detrimental effects on both paintwork and chrome, such as water spots, sun fading and of course scratches. Whether you own an unrestored example with delicate original paint or a freshly restored example with a mile-deep shine, these components need protection.

The ideal conditions are indoors, dry, dark and covered. Accessing the correct knowledge for simple areas such as car cover choice can have huge benefits to your paintwork, and although finding such a space in central London can be difficult, the investment is undoubtedly worth it. After all, it’s the first things anyone sees…

 

Climate

Put simply, classic cars need no encouragement to rust. That’s not to say they are overly delicate beasts, but some small oversights in storage can cause big problems long term.

Beyond visible moisture, climate and humidity of the space comes into play when considering long term storage. Moisture needs certain conditions to prosper, and having the incorrect climate, or most commonly a variable climate, can encourage moisture to develop and linger around your car. Be sure to assess the climate of any space your car is being held in for extended periods.

 

Mechanical and electrical components

Though they are works of art, classic cars are designed to move, and as a result the life of their componentry can be greatly diminished if left static for too long.

As such, it is important to routinely get these components moving. Batteries can quickly lose charge if left unattended, and delicate components such as fuses can find themselves ravaged by time. Ensuring correct starting procedures are adhered to, with regular checks of spark plugs and carburettor, will pay dividends for your engine. Be sure to move the car back and forth, even if only slightly, to alleviate brake seizure. This will also help with another common issue – square tyres.

 

Square tyres

This is not an issue only faced by classic cars, but extended periods of time weight bearing on a singular contact patch can cause car tyres to flatten and change shape. The levels of this are of course variable between different cars, but even a lightweight racer can fall foul of this without due attention.

Monitoring tyre pressures, as well as routinely moving the car back and forth, can alleviate this issue. With classic car tyres especially this is worth keeping an eye on, as period correct replacements can be costly.

With the consumer desire for superlative car storage higher than ever, the term ‘climate control’ is now commonly included in most descriptions for a dehumidified car storage environment. While the basic meaning is understood, less commonly discussed are the factors involved in controlling climate and, more importantly, what these physically mean for your vehicle when in storage. True climate control requires the monitoring and control of two variables: temperature and humidity. To understand the importance of controlling these two variables, you must also understand the results of exposing your car to an uncontrolled environment. Temperature It is well known that a cold environment is not preferable for storing a car, especially when considering long term car storage, with a mix of metal, perishable componentry and soft interior furnishings at risk of contracting and accelerating the aging process. A common misconception is that simply heating your storage area solves temperature-related problems, but unfortunately there are more factors to consider. Warm air is able to carry more moisture than colder air, therefore potentially increasing humidity. However, should the air be too cold it can reach ‘dew point’. At this point the air is fully saturated, and should anything else in your storage area be below this dew point condensation will form and corrosion risk rises dramatically. Furthermore, a particularly damaging yet less documented detrimental factor is a rapid change in temperature – such as pulling your car out from a toasty garage into a crisp day. As with any material, this change in temperature can cause rapid contraction and expansion which is ultimately damaging to your car, and if this is a common occurrence can quickly impact vehicle condition. Humidity When it comes to humidity, there is a fine line to walk. It is commonly understood that too high a humidity level will introduce moisture to the vehicle, and therefore a common mistake is to reduce the humidity too much. By drying out the air too much there is a risk of dashboards splitting, wood trim perishing and leather cracking due to a damaging lack of moisture. Industry grade dehumidifiers reduce and maintain humidity, which is a key differentiator from domestic units which simply reduce. Almost as important as the dehumidification is the monitoring of this, with top-tier storage facilities monitoring this on a second-by-second basis and routinely assessing the environment. Windrush Car Storage are experts in climate control and dehumidified car storage, so much so that we consult on the appropriate storage of perishable items out with automotive.

Air in the natural environment contains a certain amount of moisture as is necessary for plants and animals to exist. In car storage the aim is to control the amount to a manageable level. The ratio of the amount of moisture in the air compared to the maximum that the air can hold at a given temperature is called Relative Humidity or RH. It is expressed as a percentage. For any given amount of moisture, the higher the air temperature the lower the RH%. Equally the lower the air temperature is the higher the RH%. In winter the air appears to be noticeably wetter than in summer. It is the cooling of air that causes the problems. As air cools it can hold less moisture until a point is reached where the air is fully saturated (100% RH) – known as the dew point. If the car, tools, or anything else in this environment, is at a temperature below the dew point of this air, moisture is then given up by the air as condensation. This manifests itself as wet car surfaces, rust on tools, damp paperwork etc. Because the moisture condensed out from the air is pure distilled water it is also the ideal environment to encourage the growth of moulds and fungal spores, something you certainly don’t want to have to worry about with long term car storage. The solution to the problem is to reduce the dew point to a level below the temperature of any part of the garage and its contents AND to keep the RH% within controlled levels.

Due to the multitude of different materials present in any car, whether it be a classic, vintage or modern vehicle, there is a very specific environment in which vehicles should be stored to maintain condition. Moisture is the cause of rust and mould and it is this which needs to be managed. At Windrush Car Storage we have spent (and spend) great deal of time researching the different opinions and ‘best practice’ for the storing your pride and joy in the best possible environment. In summary there are several options: Heating Whilst we may believe this is going to be ‘good’ for your pride and joy, there are several drawbacks. Firstly it’s expensive, how many of our garages are insulated? This means that the heater will be going a lot of time, with a lot of the heat straight out of the roof and walls. Secondly the heat has to come from somewhere. This usually means that the method of doing this has introduced a fire risk, not ideal. Finally, warm air does not necessarily mean dry air. By heating the air the amount of moisture it can hold actually rises. If you brought your vehicle out of the cold into your nice warm garage, condensation would immediately form on all of the surfaces (similar to taking a milk bottle out of the fridge and into the warmer air of your kitchen). Further information on this topic can be found by clicking here. Ventilation For air to form condensation it needs to be still. (On a windy cold night you’ll never find condensation on your lawn whereas on a cold, still night you will!) By keeping the air moving in your garage it is possible to prevent condensation forming. The downside of this is that the air can still be laden with moisture and wherever the air is allowed to become still (inside the engine bay, exhaust, interior etc) condensation can form starting the rusting or mould process. Plastic Enclosures The next step on from ventilating the whole garage is to place the vehicle inside a purpose built enclosure a little larger than the vehicle where powerful fans draw in air through filters to remove any dust particles and then circulate the air around the vehicle. Several manufacturers supply systems that enclose the car completely in a plastic ‘bubble.’ Advantages are that 99% of dust is filtered out and air is continually being moved by fans to prevent condensation forming. These also have the additional benefit of preventing any objects accidentally coming into contact with the bodywork. The best in our opinion have an internal supporting framework, such as the Airflow AirChamber. Dehumidification The preferred method of removing moisture from the air and regarded as ‘best practice’ in the vehicle storage industry is by dehumidifying the storage environment. Dehumidifying allows vehicles stored in a garage to remain condensation and corrosion free. Units reduce and then maintain the humidity. It is important not to dry the air too much as a relative humidity (RH) drier than 55% may dry any wood (dashboards) or leather too much, causing them to warp and crack. Anything ‘wetter’ than a RH of 55% will allow exposed, untreated metal surfaces to begin the corrosion process. This can include inside the cylinders, brake drums/disks, exhausts and the inside of your cars’ chassis. More advanced dehumidifiers have in-built humidistats to ensure that the air does not become too dry or too wet by turning the machines on and off as required. The Windrush Car Storage Chosen Method At Windrush Car Storage we have chosen to dehumidify all our buildings with dehumidifiers which monitor and maintain a target RH of 55%. As the ultimate level of protection we then offer to place vehicles inside AirChambers which then offer the ultimate protection for any vehicle in storage by filtering any dust particles out of the air before it enters the AirChamber. From everyday, to prestige and classic car storage, Windrush can provide you with a state-of-the-art, professional and passion driven service for all your car storage needs.
