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

Both brushes work great. The heavy duty knotted one really eats into caked on material and the brass wire one takes off light duty material without gouging.

Worked great. Saved a ton of time descaling the rear of my bronco. Definitely worth it.

when I purchased these I didnt know if it was going to be strong enough to get the rust off the grounds of my car with a cordless drill. These things are heavy duty I bought a different one before at AutoZone it was alright but these took the rust off in seconds and I didnt have to sit there and keep going and going I would definitely recommend these for rust on metal Id give these ten stars they work awesome ( try to put a video on but it wont for some reason Ill try later on my PC)

Arrived quickly.. works GREAT.. %jamy.. hang in there lil buddy.. im a shower not a grower so things will work out for you!

Worked great for removing rust from an old bbq

Built with quality wire and performs as expected.

Gets the job done. What more can I say?

performs as expected-I wish the brass one was triple twisted for higher rpm use.

These little guys are tough, and mean. The knotted stainless one in particular is very aggressive on rust caked on steel, and yest it doesnt sacrifice itself to the job, like unknotted ones tend to. Fairly priced, should last awhile.

Works as intended. Wire doesn’t come apart like other brushes. I use it to age wood.
