Classic Car Care – Why You Need to Protect It from the Impacts of Humidity

Classic Car Care – Why You Need to Protect It from the Impacts of Humidity

Car storage is at the core of classic car care. Without the appropriate environment and carefully monitored conditions, our cars are vulnerable to the adverse effects that impact on our ability to preserve the vehicle in a pristine condition. Humidity is one of those conditions that should be at the top of every classic car owner’s list of priorities.


We all know that humidity causes rust. When iron and steel are exposed to moisture in the air, ions in the water cause oxygen atoms in the air and iron atoms in the metal to combine, resulting in rust. This is purely a result of the humidity levels rather than having any relation to temperature.

Controlling humidity presents a specific challenge for classic car care in the UK, where there’s an average relative humidity (RH) of 80%. When stats show that the best RH for our own health and comfort is 30-50%, imagine what havoc an 80% RH could be reaping on our beloved classic cars.

In fact, you don’t have to imagine. The corrosion of steel begins at 55% RH but increases significantly at levels above 60% RH. If your storage facility doesn’t factor in humidity, you’re missing out what should be a core element in protecting your classic car.

Classic car interiors:

Rust isn’t the only problem. Humidity leads to problems in the classic car interiors, too. Leather interiors can present a particular problem, as moisture causes the material to crack and weaken and allows mould to grow. Damp smelling interiors can usually identify this- usually found in classic cars that haven’t been stored appropriately.

Rubber seals will also be affected by a high humidity environment. The deterioration of these seals will lead to accelerated perishing.

Classic car care requires a lot of investment. What we need to avoid is investing resources into ineffective solutions that don’t prevent damage to the car, which then costs more to fix.

Some classic car owners rely on a protective bubble, dehumidifier bags or a classic car cover. While this solution keeps the dust off your car, there’s no protection from humidity.

Controlling the humidity of the environment is integral to classic car care. With that in mind, a solution that can efficiently remove moisture from the air and monitor humidity levels is a necessity for effectively preserving classic cars.

Removing moisture is the only effective way to control RH and protect against corrosion truly. It also has the additional benefit of being more energy-efficient than other alternatives.

Opting for a desiccant dehumidification system that is tailored to meet your classic car care requirements is the most effective means of protecting your car from humidity.

With over 22 years of experience, we have controlled environmental conditions in a wide range of single, double, treble and purpose-built garages, as well as in underground car storage and above ground warehouses. Each system is uniquely designed with the customer’s individual needs in mind. Click here to find out how it works.

Classic car enthusiasts each have a fundamental understanding of the need to preserve timeless designs. However, to maintain the top condition of our classic cars, we need to embrace cutting edge solutions that will protect our cars well into the future.  Ultimately, it’s clear that the key to classic car care is an effective humidity control solution.
