I’ve got one of those cleaning bars that are supposed to clean the sanding discs and whatnot. Do those work for anybody? As you can guess I have not had good luck with them. It seems the paper wears out on my ROS before I get a chance to use it, same thing on my drum sander. And when the paper on the drum sander loads up in a spot and then puts a nice burn mark racing stripe on the wood the bar sure don’t seem to be able to remove that from the paper. Or am I asking too much? I never tried it on my 12” disc sander, never seemed to have the need too. the paper on it lasts pretty long and it gets used a lot.

BlankMan, I’ve had pretty good luck with them on a bench-mounted belt/disk sander and an oscillating spindle sander. But . . . you have to clean the belt JUST before the pitch/glue/finish hardens to that epoxy-like ball of cosmic goo. It appears from your write-up that we’ve tried just the opposite situations; I’ve never tried it on either of my handheld (both 1/4-sheet palm) sanders.

Whit is right, you have to use them to prevent the paper from clogging up. I use them all the time and my belts and disc last 3-4 times longer.

I have alot of luck with them … I have a spindle attachment on my Drill press, Drum Sander, and Disc/Belt sander, and a hand held belt sander I use it on … As long as i keep an eye on em and keep them from getting too much build up before I use the Cleaner on it … works like a charm … I also found the lighter pressure I use on the sanding the better it works … If i sand with alot of pressure it clogs too much to clean off …

So they do work, I probably waited too long then because that cosmic goo has nailed the paper on my drum sander too many times. When using it I try not to take off too much at a time, maybe 0.005” but never more then 0.015” at a pass. I’ll have to keep an eye on it then and stop periodically and look at the paper, I have never really done that. Usually I look when I’m done sanding what ever I’m sanding and that can be after many passes. And maybe the paper on my ROS isn’t worn out but loaded up. It’s hard to tell since the sandpaper I’m using is yellowish to start with so it’s hard to see light colored sawdust on them.

I really think it helps a lot. I use one on my belt sander, drum sander, and thickness sander. Really seems to help, but you need to use it before the dreaded black line appears.

I have never tried it on a ROS. I’m not sure why, but the disks are so cheap and easy to replace.

I tried some sheet paper from Harbor Freight last weekend, and it was absolutely horrible. Never again. The quality of paper makes a huge difference.

I use one of those blocks all of the time on belt and disk sanders … they do fine so long as there is minimal pitch buildup. I think they key is to hit them before the pitch starts to build.

I have had great luck with the bars. I have a lot of sanders between 2 school shops and my home shop. I use them on disc, belt, spindle sanders, even a dremel bit. I haven’t tried on the ROS, but I will try that.
They can clean up most of what a high school freshman can leave behind.
