Methods for cleaning a car chassis: 1. Lift the car to working height and rinse the chassis with a high-pressure water jet. Pay special attention to curved areas, edges, and fender liners, ensuring no mud or grease remains; 2. For particularly stubborn grease, use degreasing cleaner and a scraper to carefully clean until the chassis returns to its original color; 3. If rust is present, remove it with sandpaper. After cleaning, dry and wipe the chassis, then evenly spray a rust-proofing agent to form a durable protective film. Allow it to air dry naturally after completion. The chassis refers to the combination of the transmission system, running gear, steering system, and braking system in a car. It supports and mounts the engine and its components, forming the overall shape of the vehicle, bearing the engine's power, and ensuring normal operation.

I'm quite skilled at cleaning my car's undercarriage. Drive the car to a level spot, carefully lift it with a hydraulic jack, and ensure it's stably supported. Prepare a high-pressure water gun or a regular hose, and start rinsing from the inner side of the wheels to remove large chunks of mud and salt. For stubborn stains, use a soft-bristle brush dipped in automotive undercarriage cleaner to gently scrub, avoiding sensitive components like brake discs or electronic connectors. After washing, dry with compressed air or let it air dry naturally, then apply some rust-proof spray to protect the metal. Clean quarterly to prevent corrosion, and be more diligent in winter—road salt buildup can easily corrode the undercarriage sheet metal. This method saves on repair costs and helps detect cracks or oil leaks early.

As someone who's been driving for half a lifetime, I emphasize that safety comes first when cleaning the chassis. First, find a reliable car wash shop or wear goggles and gloves when DIY-ing. Avoid directing water at the engine base or wiring harnesses, as high-pressure water can seep into components and cause short circuits. If doing it yourself, choose a chassis-specific cleaner, gently scrub, and rinse thoroughly. Regular cleaning is crucial—salt and mud accelerate rust, affecting the vehicle's lifespan. For peace of mind: inspect every two months, and wash more frequently before and after the rainy season. For heavy grease, seek professional workshops to avoid damaging the coating. This habit makes the car more durable and prevents unexpected breakdowns.

The simplest way to wash the chassis by myself: Find a car lift or go to a car wash, first rinse off the mud. Avoid wetting the engine or electrical systems, hand-brushing dirt in corners is sufficient. Focus on regular rust prevention.

I always maintain my vehicle, with chassis cleaning being the core. First, ensure the car is parked stably and safely. Rinse off mud with clean water, and use a neutral cleaner for oil stains. After rinsing, dry thoroughly and apply an anti-rust coating to prevent corrosion. It is recommended to clean and protect the metal every season or after snow to prolong its lifespan. Be careful not to let water accumulate in sensitive areas.
