A clean, well-maintained belt ensures efficient power transfer and prevents slippage, which can cause accessory failure. Dirt, oil, or grime buildup can reduce grip, cause squealing, and eventually lead to belt damage or failure. Regular maintenance, including cleaning, prolongs belt lifespan and ensures your vehicle runs smoothly.
