3M 7525 Scotch-Brite Roloc Bristle Disc Yellow 2 Pack of 2

We use the yellow and white to clean the calcium buildup on our pool tile it’s hard to believe but works beautifully and does not scratch the tile. We use a pneumatic die grinder and you don’t get any water contamination. Depending on calcium buildup they last pretty good but wish they lasted longer.

These work great for cleaning surfaces without marring or eroding them, but wear very quickly for the price.

Good

Works really well also ordered the white ones

These work great for cleaning without removing much material. Very pleased with these. Recently I purchased a new lawn mower blade that had a sticker with enough glue to hold an elephant, maybe an exaggeration but it sure didn’t want to come off even with soapy water and a few rounds of goo gone. Just when I was loving life and praising the good people who thought a lawn more blade really needs a sticker to cover the holes, I pulled out my die grinder stuck on one of these wheels and in a couple of minutes I had a shiny blade with no trace of sticker. Just to check I put the blade on a balancer and it was still perfectly balanced. I have used it for cleaning around wheel hubs and mounting surfaces and always see shiny metal with minimal material removal. I am sure it takes off some of the metal but it can’t be much.

3m quality

Cleaned up my cylinder heads great

Definitely a must have in your tool collection. Great for removing silicone and gasket materials from surfaces and bolts.

just what the mechanic wanted

Does a great job wish they lasted longer be careful when using not to run in to objects around it It tears the bristles up very quickly I work excellent to clean gasket surfaces like water pump timing cover differentials intakes I use it in the automotive industry
