I made the mistake of sanding a painted surface with my old 6x48 belt
sander. Now, of course, the belt is clogged with paint. I got most of
it out, but there is still enough to make it practically useless. I
have tried a few things. The big eraser thingy didn't do much. trying
to loosen it with water and mineral spirits didn't do anything. The
thing that did the most good was creasing it while rolling it between my
hands (hope you can get the drift of that) so a lot of it broke off.
But there is still too much paint on it. Any ideers on getting the rest
of it off??
You can try a wire brush. Run the sander and brush the brush against
the belt. Now that's a tortured sentence. You will get some paint off
and some grit off, but the belt was a tosser anyway. Good luck.

If I had some in my shop, I would put a dab of paint
stripper on part of the belt.
It would remove the paint, and might soften (or even remove)
the bond holding the grit. But if the bond survived you
could easily renew the belt.
All the best,
Been there done that and thanks for your comments about the mineral spirits
and or water. Regular belt sander belt? toss it. I have had the same
problem except on a $10, 22" drum sander belt and tried the rubber belt
cleaner stick, PVC pipe, a wooden dowel hard wood, with results that
amounted to a waste of time.
I did however find like you, that if you fold the paper over on it self to
create that crease, the paint simply popped off when rubbed with a finger
IIRC. That is a LOT of bending and folding on a 3" wide strip of paper that
is over 10' long.
If the paint was latex then a product called "Goof Off" would probably do
you some good...Its quite effective at softening or removing paint without
hurting much else including carpet, cloth and even car paint. It can be
found in any reasonable hardware or big box store. I'd brush some one, soak
a bit, brush lightly with a wire brush and maybe if needed rinse with water
I've made the same mistake using several different sanding media. You
might try sanding something really hard like a piece of steel. This might
heat the paint residue up through friction, make it soften and come off.
Second suggestion is to try sanding a piece of concrete, maybe a chunk of
concrete brick or cinder block. This will act as a strong abrasive and
grind the paint off. You also risk grinding some of the grit off of the
belt this way too.
Thanks all. Lotsa good things to try. I am trying to save the belt
because it is a relatively new and high quality blue belt that cost me
over $25. A little time to clean it is not a problem for me. Although
I did say that the belt was "useless" that isn't exactly true. I am
still using it but it's effectiveness is greatly diminished.
Someone was also jealous of my 6x48 belt sander, but you may not be so
jealous when I tell you that it is a circa 1952 Sears Craftsman sander
that I inherited from my MOM. LOL. It is a little finicky to get the
belt tracking straight but it works. OK, so maybe more than a little
finicky. And there is absolutely NO dust collection. But Sears still
had parts for it when I got it about 4 years ago. How about that?
So I think I will start by trying a little bit of paint stripper to see
how that works. Maybe a little Goof Off (the paint WAS latex and I do
have a little bit of Goof Off) on another little piece. With any luck
at all maybe the bonding will stay intact. Someone else mentioned
trying a wire brush, and I have tried that with no success at all. I
don't want to try sanding a piece of metal because a while back I made
some metal parts for my 9" Southbend lathe and sanded them on this
sander. The belt was toast in just a few minutes. I also have some
real TSP around here somewhere that I can try. If all that fails maybe
I can try using a piece of 36 grit paper and see if that can knock some
of it off.
Thanks again for all the suggestions. I will let you know how it goes.
