Fiberglass Pen Scratch Brush Set - Jewelry Cleaning Brush with Steel, Brass, Nylon, Fiberglass Tips for Corrosion Remover and Rust, Jewelry, Electrical Circuit Boards and Auto Body Work

Work well, I use to clean up dirty/corroded battery contacts after removing leaky alkaline batteries. Handy to have around when you need them.

This is a pretty nice set and at least at the time I bought them they were way cheaper than the next options. The brushes seem sturdy, are easy to extend and retract with a twist, and come in a nice sleeve to carry and keep them together. Would recommend!

Expensive for small tips. Would be nice if they came with refills. As soon as i used any if them they looked worn and smashed up. Hoping they last bc they can be very helpful.

I have used all of these pens. Mainly for cleaning up light corrosion on small metal parts and they all work well, while experiencing none of the problems with the retraction mechanism that some have experienced. If you only need the fiberglass material, however, an even better choice would be the Generic KSB Fiberglass Scratch Pen with Refills, as the fiberglass used in this set is the most effective of all with the best abrasive properties for this type of material, while also being a really good value.

I already have one set and wanted another one, these are great.

I bought these on recommendation. They do work, but I was expecting more. I guess it depends on what kind of tarnish/rust they are used on.It would have been nice if they had labeled the actual brushes instead of just the pouch. I ended up using a label maker to mark them.

I recommend this set.I picked these up after reading other sets' reviews.I recommend this set. The different material brushes made cleaning rust off of steel coins a lot easier.I used these brushes to clean off some tokens that i knew would be "worthless" if cleaned or not.(PLEASE DON'T CLEAN COINS UNLESS YOU KNOW) This isn't a warning of "i don't know how" but rather a "get it appraised before cleaning" if you think its worth anything.personally, it is very pleasing to take an old copper token and after a little work is either completely shiny, or if you have a good arm, you can shine part of the coin leaving some patina behind.loved these. Have fun!
