This helps remove any abrasive contaminants that could potentially cause wear on moving parts or lodging in the window channels.
Lubrication is also a key aspect, though it should be applied judiciously. A light application of a high-quality silicone spray or a dry film lubricant on the cable, gears, and pivot points can significantly reduce friction and ensure smooth operation. Avoid using petroleum-based lubricants, as these can attract dirt and debris, potentially creating a grinding paste that accelerates wear. Consulting your vehicle’s service manual or the regulator manufacturer’s recommendations for specific lubrication points and products is always advisable.
