How to Clean the Car Chassis?

Car chassis cleaning method is as follows: 1. Lift the car to working height, rinse the chassis with high-pressure water jets, and repeatedly flush curved areas, edges, and fender parts to ensure no mud or grease adheres. 2. For particularly thick grease stains, use degreaser and a scraper to carefully clean until the chassis reveals its original color. If rust is present, use sandpaper to remove it. 3. Dry and wipe the car chassis clean, then evenly spray rust-proofing agent to form a long-lasting protective film. Allow it to air dry naturally after completion.
I've washed the car chassis several times and find it not too difficult, but requires attention to detail. First, ensure the engine is off and cooled for at least half an hour before starting to prevent thermal deformation of components. I use a garden hose connected to a tap—plain water works fine. Squat down to rinse off surface dirt first, avoiding high-pressure washers that might damage wiring. For hard-to-reach spots like exhaust pipes or drive shafts, an old toothbrush dipped in dish soap works great for degreasing. After rinsing, wipe dry with a cloth or park the car in a ventilated area to air-dry, otherwise the chassis may rust, and trapped moisture freezing in winter can cause bigger issues. Monthly washing is recommended, especially after rain or driving on dusty roads, to prevent corrosion and extend lifespan. If heavy grease buildup occurs, inspect promptly for oil leaks and repair if needed. The whole process takes about 30 minutes—safe, eco-friendly, and saves garage fees.
