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

It definitely will not hurt an aluminum oil pan! Barely able to remove RTV silicone, but eventually it gets the job done.

Awesome product arrived before the delivery date and was exactly what it said. I use these to clean engine blocks and they work awesome. Alot cheaper then getting them through the parts store as well

just what the mechanic wanted

These roloc discs are fantastic for automotive use.

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.

Works really well also ordered the white ones

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.

First these are not 3M brand Roloc discs. I have purchased 100’s for my business. These are horrible and cheap quality. They should not be priced as 3M brand!!!!! Cheap “China” reproduction for sure…Order at own risk. Should be like $2 bucks each, Amazon should not be selling counterfeit/reproduction items. Shame to see Amazon no longer sells quality items. I could’ve purchased on Alibibi and waiting 30 days to receive the same quantity for tenth of the price. Shame on Amazon!!!!

Good

Seem like good quality and I got what was in the picture but it is way to aggressive for aluminum gasket surfaces.
