How do I remove damp in a car?

The best thing for removing damp is to let your car air out. If it’s a mild day with no chance of rain, open up the doors and windows for as long as you can.  

Check the vehicle for leaks and remove any excess moisture with dry cloths. And if you don’t have a spell of decent weather, try using a fan or hairdryer – or turn on the heating inside the car, for the same result.

How can I prevent damp in a car?

There are a few simple ways to keep damp from forming in your vehicle. 

Keep an eye out for signs of moisture

Watching for leaks and condensation, and acting quickly, will keep your car free of damp. Try to keep the windows open when you have hot drinks and food, and remove anything wet as quickly as possible. Check the boot of the car and other areas, regularly, for signs of a leak.  

Keep your car covered

If you keep your car in a garage, using a lightweight cover that’s breathable will help keep it free from damp. If you can, use a dehumidifier or a low-powered heater to keep the air dry.

Just remember that any car that’s stored for long periods should be taken for a short drive at least once a month. This will keep everything ticking over and give it a blast of fresh air.

Use your air con and windows

It sounds simple, but keeping the windows ajar on hot days and closing them on wet days will help keep your car damp-free. 

Turning your air conditioning on for a while during winter, every few weeks, can also boost circulation and stop any pipes or vents from clogging up.

Does having damp in my car affect my insurance?

While damp in your car won’t affect your insurance, it could damage your car. Leaky parts, mould and water can cause problems for your car, leading to expensive vehicle repairs.
