I work as a maintenance mechanic dealing with both electrical and mechanical issues, lost my tool box due to a fire needed to replace this tool I have utilized this tool for years to eliminate corrosion on all types of circuit boards and edge connectors , remove light and heavy corrosion without destroying the underlying metal plating does not leave a residue and the fact that you can extend the fibers also helps to clean inside connectors also , a quick blow off with air and all busted fibers are gone, glade I stumbled across these items again, would highly recommend any one dealing with electronic circuits that start having weird results to clean connections with this tool

The shipping was fast, the brush is very good quality, I have used it many times since purchasing it and it performs flawlessly. I don’t know how I was able to function for so many years without one. A must for any pirinted circuit board repairs, and for electronics repair in general. I even have used it to remove marks from kitchen pots and pans. Indespensable for any “ do it yourselfers”. These brushes should be standard equipment in every tool set whether it is, as in my case electronics, or just for use around your Home. Great Product!

I was convinced I would not get off the “scratches” on my stovetop after using all kinds of cooktop cleaner & renewer but this actually got off the baked on food that I mistook for scratches because nothing chemical wise could get it clean. It looks brand new after using this pen!

I have used some kind of nylon fiberglass pen for cleaning my camera electrical connections for over thirty years and these are the BEST....would buy again and I will.

This is the ONE to buy. You can take a badly tarnished or corroded penny and make it look freshly minted. I use these in electronic repair and assembly. They are esoecially useful for cleaning up batterg contacts that have been damaged by leaking batteries. There are several kinds of scratch brushes on the market, nylon, brass, etc. Beware of cheap Chinese knock offs, they're a waste of money.
