Two weeks ago, I put on new 60g belt on my old Ryobi 16-32 drum sander and proceed to carefully sand some old 12” X 36” shelving boards that I had stored in my shop for about 12 years. Not sure if was pine or Douglas fir, but to my chagrin I managed to gum up my new belt (photo 1) pretty badly. Rather than discard the belt I decided to see if I could loosen the debris with the application of a little heat using my HF heat gun (photo 2), followed by brushing with a small stainless wire brush (photo 3). I used the heat gun (low setting) on one small area at a time and immediately used the wire brush and was able to remove the majority of the gummed up stuff on the belt. I never applied the heat gun for more that 10-15 sec at a time so as to not soften the belt adhesive, and the belt never became so hot that it was uncomfortable to touch. It took about 15 minutes to clean the entire belt. The last photo is after one week of use post-clearing. Seems to work, and better than buying a new belt.

Great idea. There was some talk on here in another thread about using ammonia. I’ve got a few 4×36 belts that need help. I think I’ll give both a try. Yours sounds much less messy :)

Sure, and they are great for keeping the belt clean from regular sanding debris, but when you get that glossy fouling, it doesn’t do a thing to remove it.

I like them cuz if you use it every few sandings or between projects it prevents the glossy fouling from forming in the first place. It also seems to improve the performance of the paper when its clean. I get a weird feeling of success when I run that thing over the drum and it wipes the paper clean. :-)

Again, you’re right. I keep mine handy and rub my sander over it frequently. However, with belt sanders or drum sanders, there’s more heat involved and you can quickly get that glossy fouling.

Are you talking about being in the shop or in the bathroom? If it’s the latter, you’re a tougher man than I am… lol

That’s why I want a Flatmaster. The heat is the thing. https://youtu.be/lgPLOnXCmdU

But so as not to hijack the thread I’d suggest cleaning as best you can then going forward clean it often.
