What is the best method to remove glazing from a squeaking drive belt?

Using chalk as an abrasive is a practical method to remove glazing from a squeaking drive belt. When a belt is subjected to excessive wear, heat, or improper tension, it can develop a glossy, hardened surface known as glazing. This condition can lead to slipping and increased noise.

Applying chalk to the belt creates a slight abrasive effect, which can help to dull the hard surface of the glazing. This surface roughening can improve the belt's grip on the pulleys, reducing squeaking and restoring proper function. Chalk is also a dry material that does not introduce oil or solvents which might cause further slipping or damage to the belt's surface.

In contrast, replacing the belt may be necessary if it is excessively worn or damaged, but if the glazing is the only issue, it may not be the most cost-effective or immediate solution. Using a solvent spray could dissolve or soften debris but may worsen the glazing. Applying lubricant is counterproductive because it could exacerbate slipping problems rather than resolve them.
