Corrosion might sound like a lab term, but on a car it’s just plain old rust that eats away metal parts. If you’ve ever seen orange streaks on a wheel arch or a flaky patch on the door, you’ve already met corrosion. The good news is you don’t need a mechanic’s degree to keep it at bay. A few everyday habits can stop rust before it hurts your car’s look or its value.
Rust forms when water, oxygen, and salt mix on a metal surface. In the UK, rain and road salt are a perfect recipe. Small chips in paint expose bare metal, and that’s where the reaction starts. Even tiny scratches on the bumper can become a rust hotspot if you let moisture sit there. Poor drainage, like clogged gutters or a stuck door seal, also traps water and speeds up the process.
First, keep the surface clean and dry. A quick wash after a drive in the rain or after winter sanding removes salt that fuels rust. Don’t forget the undercarriage – that’s where most salt settles. A monthly rinse with a pressure washer works wonders.
Second, protect the paint. Waxing once a month creates a barrier that blocks water and UV light. If you notice a chip, fill it with touch‑up paint right away. The quicker you cover the metal, the less time rust has to start.
Third, use rust‑preventive products. Sprays called undercoatings or rust converters can be applied to hidden areas like wheel wells and frame rails. They’re cheap, easy to spray, and give the metal a protective layer that lasts for years.
Fourth, check drainage points. Look at the bottom of doors, trunk seals, and around the windshield. If you see water pooling, clean the area and replace any worn seals. Good drainage means less standing water and less rust.
Finally, store the car in a dry place when you can. A garage or a covered parking spot reduces exposure to rain and humidity. If you have to park outside, use a breathable car cover – it keeps dust off while still letting moisture escape.
By making these habits part of your routine, you’ll see far fewer rust patches and keep your car looking sharp. Remember, rust doesn’t disappear on its own; it only spreads. A little effort today saves you big repairs later, and it keeps the resale value of your vehicle higher. So grab a sponge, a wax bottle, and a spray can, and give corrosion the boot.
