Engine cleaner should be used to wash a motorcycle. Below is relevant information about cleaning agents: Function of cleaning agents: Engine internal cleaning agents are products developed to address the formation of sludge, gum, carbon deposits, paint films, dirt, and other sediments inside the lubrication system. Composed of highly effective cleaning components, they are additives capable of automatically cleaning the internal system of the lubrication system. Gasoline cleaner: The main component of engine carbon deposits is impurities in gasoline. Therefore, gasoline with higher cleanliness has a weaker tendency to form carbon deposits. Choosing a genuine gasoline cleaner helps remove carbon deposits inside the engine, effectively preventing the formation of carbon deposit layers on metal surfaces, gradually activating existing carbon deposit particles and slowly removing them, thereby protecting the engine from damage.

I once used laundry detergent to wash my motorcycle, and the paint ended up completely matte. Later, at the repair shop, I noticed the mechanic was using a neutral car wash soap, and that’s when I realized motorcycle cleaning requires special care. For metal parts, it’s recommended to use a stainless steel-specific cleaner and avoid strong acids or alkalis. Engine grease requires a high-solubility engine cleaning foam, while for parts like the chain, you should soak them in kerosene first and then rinse with a dedicated cleaner. After washing the entire bike, make sure to dry it with a soft towel—otherwise, chrome parts and bearings can rust in no time. Finally, remember to spray a protectant on rubber components to extend their lifespan.

Once I used dish soap to wash my motorcycle, and the next day I found white corrosion spots on the rims. Choosing motorcycle cleaners requires great attention: use neutral car wash liquid mixed with water for plastic parts to prevent fading. For the engine, biodegradable cleaners are more environmentally friendly. The chain must be cleaned with a specialized cleaner containing anti-rust ingredients. Never use ordinary cleaners on leather seats; instead, use oil-containing leather conditioners. Never spray high-pressure water directly near the carburetor—I learned this the hard way.

Our heavy motorcycle club members all use pH-neutral foam cleaners. Spray and wait five minutes for grease to soften before rinsing. Windshields work best with ethanol-based cleaners, while exhaust pipe high-temperature areas require cooled aluminum foil cleaner. Brake discs must avoid cleaners to prevent braking issues. Clean chains using a toothbrush dipped in kerosene for crevices, then apply chain oil afterward. Remember never to rinse a hot engine - sudden cooling can cause deformation.

Don't cut corners when washing your motorcycle. My neighbor used washing machine detergent to clean his bike, and all the chrome parts turned blue. For a full wash, use dedicated motorcycle wash diluted in warm water with a sponge for gentler cleaning. Wipe shock absorbers with isopropyl alcohol to avoid damaging the seals. Use metal polish on the exhaust pipe but keep it away from brake discs. Condition leather seats with saddle soap, and avoid high-pressure washing near electrical connectors. After washing, use compressed air to blow water out of crevices - it's more reliable than sun drying.
