Katzco Wire Cup Brush - 2 Pack Knotted and Crimped Cups for Rust Removal, Corrosion and Paint - Hardened Steel Wire for Reduced Wire Breakage and Longer Life

These things are insanely heavy duty! I ordered them hoping to find something to clean my fiberglass shower basin. The steel one is a little too heavy duty. The brass one does the job fantastic! I just couldnt use it with a drill because its built so sturty! I can use it by hand to get stuff that hadnt been removed in like 10 years!

They seem to hold very well for now.

So far so good. Only used once to remove. Works great

Worked as expected.

Great brushes.I used then to take a old layer of paint off an antique iron bed. Worked like a charm! SAVED MY ACHING BACK

I ordered these to help de-rust my car. my car has a lot of rust so i though id buy a cheaper option so if the wires started to come off, it was no big deal. two solid days later, and not a single wire has broken off or bent, and my car has never looked better. same goes for my sisters rotors...NICE AND SHINY :)

Got the job done. Maybe the shaft should not be round as increased pressure made it slip.

tough stuff for rustic stuff

Used this to strip the paint and rust off a metal porch glider, shows now signs of wear or clogging from paint. Thanks Little Jamy and Donald!

This brush is only to be used in the most extreme cases and resilient of surface areas. Its very coarse and strong wires will scratch off any paint. rust or any other hard to remove substance you can think of.
