Protecting Classic Cars with Humidity Control

When it comes to protecting classic cars, achieving the recommended relative humidity of 50% in the storage environment becomes vital to maintaining the value of your investment. This humidity level strikes the perfect balance, ensuring that leather and rubber components remain undamaged, as a result of an environment that is too dry whilst avoiding problems related to damp air such as rust.


Cleanrooms are engineered spaces where the concentration of airborne particulates is kept exceptionally low. They are designed to shield everything from dust and airborne organisms to vaporized particles from the materials being handled inside. The ISO classification system categorizes cleanrooms based on the allowable particle count per cubic meter at specific size ranges. A typical urban area contains around 35,000,000 particles per cubic meter in the size range of 0.5 μm and larger, equivalent to an ISO 9 certified cleanroom. On the other hand, an ISO 14644-1 level 1 certified cleanroom permits no particles in the 0.5 μm size range and only 12 particles per cubic meter of 0.3 μm and smaller.


One of the foremost concerns for classic car enthusiasts is rust. If excess moisture is present in the storage area, this will create the ideal environment for rust to develop. However, by maintaining a 50% relative humidity level through dehumidification, you create an environment that significantly reduces the risk of rust forming, offering peace of mind to every car owner.


Humid air is a catalyst for mould growth, a menace that can plague both the interior and exterior of your classic car. Dehumidification within the storage area will remove the excess moisture, ensuring that rust is unable to grow on your vehicle.


Classic cars are renowned for their pristine leather interiors. However, even the finest leather can lose its shine and structural integrity when exposed to incorrect humidity levels. Dehumidification effectively stops condensation build up on leather surfaces, allowing them to retain their colour and strength.


Beyond preventing electrical faults, dehumidification plays a pivotal role in preserving key electrical components. It acts as protection against moisture ingress, safeguarding your cars critical systems. Additionally, it ensures that essential rubber pipework remains in optimal condition. This reduces the risk of leaks and fluid loss that could otherwise compromise the reliability and integrity of your vehicle.

In conclusion, achieving a relative humidity level of 50% in your classic cars storage area is not just a preference; it’s a necessity. This will maintain the value of your classic car. It’s the key to unlocking a host of benefits that protect your vehicle from rust, mould, electrical faults, leather degradation, and fluid loss. By embracing proper humidity control, you preserve the classic car’s beauty and functionality and maintain its value in the market.
