Cleaning Drum Sander Belts
Jack Prescott
I have a 16-32 drum sander. I rolled up the "used belt" in a tight circle and immersed it in isopropyl alcohol (rubbing alcohol) in a used shampoo bottle (tall and thin to minimize the amount of alcohol needed). The belt came out almost like new with a slight amount of scrubbing with a wire brush!
The build-up usually consists of abietic acid (rosin) and is soluble in almost any alcohol such as grain, methanol, etc. Vodka would probably work too? Rubbing alcohol use to be about 95% concentration but suppliers have diluted it down to 70% and even 50% with water!!?
I have seen other methods used on YouTube and this beats the heck out of what I have seen!
