How to Clean the Sludge on the Outside of the Engine?
2 Answers
Engine sludge can be cleaned at a repair station or garage. Methods to prevent excessive automotive sludge are as follows: 1. Use high-quality fuel: According to data, fuel has a greater impact on sludge formation than lubricating oil. Using high-quality fuel reduces sludge formation, so it is recommended that car owners refuel at reputable gas stations whenever possible. 2. Choose the appropriate lubricating oil: When selecting lubricating oil, we need to determine the type based on the vehicle's daily usage. It is also important to regularly check the vehicle's oil level and replenish it promptly when it is low to reduce the pressure on the existing oil.
I remember the last time I cleaned engine sludge myself, using the most common household items. First, safety first—make sure the engine is completely cooled before starting. I wore gloves and goggles; don’t skip protection for convenience. Then, buy an engine cleaner spray and let it soak for 10 minutes to soften the sludge. If you don’t have a dedicated cleaner, diluted dish soap can work in a pinch, though it’s less effective but cheaper. Next, use a small brush to carefully scrub the corners and crevices, avoiding metal brushes to prevent damage. Finally, rinse with a low-pressure hose, avoiding direct sprays on battery cables. Dry thoroughly or let it air-dry to prevent rust. Don’t forget to regularly check for oil leaks to prevent buildup. DIY saves money but carries risks; for thick, old sludge, it’s safer to go to a professional shop. Doing it myself cost around 150 yuan.
