It seems that I need to tap the collective wisdom of the group yet again. I’ve been using self stick 12” sanding discs on my disc sander and the last couple of times, after replacing them I haven’t needed to remove the residue (maybe should have, but it was evenly dispersed, so I just applied the new disc), anyway after removing the last sanding disc, I decided this rubbery (has the look of dried contact cement) residue is too gucky and uneven to leave.
I’ve tried lacquer thinner and mineral spirits (it’s not water soluble) and they do seem to make it stickier, but short of soaking the disc in a tub of either of them for a long time, I’m looking for something that acts quickly.
A haven’t got any acetone here to try & I may just go buy some, but I was wondering if anyone has any other ideas.
Thanks -SST

Use MEK (methyl ethyl ketone). Get it at Home Depot or Lowes where you find acetone and paint thinner.

Works great for adhesives. Will get it off for sure.

I would think acetone would be the way to go.

If you can warm it up with a heat gun (or the wife’s hairdryer if she’s not home) most of the residue should scrape off with a metal putty knife. I’m surprised laq. thinner did not remove it, thats what I have used in the past.

I’ve tried the heat gun, and it simply gets stickier and ultimately dries tougher. This stuff is unbelievable. I’ll try acetone first since I just bought some, and then head to the store for MEK. Thanks everyone.

I think that the acetone will eventually get it off, but mostly it will make it gummier and move
it around a lot.

Let us know what your results are.

I tried some naptha. I set the disc flat and poured some on and kind of smeared it around to cover the guck. I then let it sit for about a half hour and it softened enough to scrape it off with a putty knife. I then put a little more on a scotchbrite pad and rubbed around &it all came off.
I don’t think I’ll let it get that bad again -SST

Try acetone or Goo Be Gone.

SST,
I have had great luck with 3M General Purpose Adhesive Cleaner. You can find it at the big box stores and at specialty automotive stores, like NAPA (where I get it). It is about $15 per quart and it works very well. Scrape the disc as clean as you can and then apply cleaner with a rag.
When done, let the rags dry completely outside, away from anything combustible. As always, protect yourself; use goggles, respirator and heavy duty gloves (thin latex gloves will melt).
