Topic tags/keywords: klingspor drum sander sand paper

Not sure exactly what happened here, guessing I ran some boards through before the glue fully dried or its just part of sanding hard maple.
The question is, can sanding belts be cleaned? Thinking this is way past gum eraser cleaning stick. I thought about tossing it in a bucket with some cleaner, but believe it best to ask here first.
Thanks.

I’ve seen folks say that soaking them in Simple Green overnight will get that off, but it’s never worked for me. My solution is to toss them when they look like that. As an aside, that appears to be a drum sander belt (?). Long ago I give up on anything finer than 150 grit, and more often than anything else, use 120 grit. The finer grits are just too easy to clog; as least for me.

Sanding belts are consumable. It is just not worth the time and effort that might go into cleaning them beyond the gum eraser. I guess you could try a wire brush, I have never done that though.

I agree that using the 180 for what I was sanding was a BIG part of the problem. I failed to check sanding grit before running the boards through it. Normally I have 80 or 120 on it.

you can find sandpaper cleaning blocks. One came with my belt sander but I have never used it so I can’t speak to its effectiveness.

I can easily get glue an sap fouled belts back to “new” with an overnight soak in a strong ammonia solution followed by laying the belt out on the patio and giving it a good hosedown with a nozzle . I use the “janitorial strength” stuff from the local ACE hardware (10%, about $6/gallon). Titebond III fouling sometimes takes another soak.

I have done this on 36 grit belts up to 220 grit which foul easily. Many of the 220’s have been soaked over 5 times and still cut great, but I have found a few that the grit has simply been worn out from use. These are drum sander strips and 6”x48” sander belts. I’ve never noticed any damage to the belt from the cleaning except a few where the identification writing on the back has faded.

Simple green works quite well, but I’ve found the ammonia is the magic bullet for the worst. I keep in in a large plastic pretzel tub with a screw-on cap to keep it sealed. The strips are loosely rolled up to fit and fully submerged.

The Rubber Block is simply an eraser….hold it to the belt as the belt is moving along…

I have had that happen more than once. I found that using paint remover worked well. lather it on, work it briefly with a fine bristle brass brush, let it sit for a little while, rinse, and hang to dry.

I use this

I’ve found it good for 1 time use, after that I change the belt. I use it on a belt/disc sander and a drum sander. 10 years and about 2/3 left.

It probably won’t help in the belt you have pictured, heavy glue is there to stay.

Hello cracknpop.

Short answer, yes you can, as to how effective it is, is the question, as I had varying results.

You may be interested to read this Blog its 2013 vintage so products may have improved.

Also you can buy 36 G for removing paint and resin.

It spossibly not much different to 40G I suspect

See what you think, quite a few LJs actually do it

The cheapest way to go around this is to buy an abrasive cleaner and use it for the cleaning purpose. It works fine with almost all types of wood sanders.

I have used a wire brush, yes it removes some grit but works.

Thanks for the feedback. Considering I have nothing to lose but a few ounces of cleaning solution, I’ll give it a go.
Don’t have Simple Green, so poured a few ounces of Purple Power in a bucket with enough water to cover the belt. Will let it soak. Have my soft brass bristle brush ready to go.

Will let you all know how it turns out.
Thanks again!

In the old days, I just used paint thinner and a brush.

Eventually, my time became more valuable than the few dollars for a belt. Even for the drum disc or edge sander.

In the old days water bed plants would take overhead sanding belts to the car wash.

The reason I ask what size bet. 3×21, 3×24,4×24, other?

The small belts aren’t worth it unless there on a edge sander…

Have your say...
