Fiberglass Scratch Brush Pen - 3 Pack - Jewelry, Watch, Coin Cleaning, Electronic Applications, Removing Rust and Corrosion

For my husband. They worked as exspected.

great replacement for worn out tool

I have many times needed to clean electrical contacts and such on my American Flyer trains and Aurora Model Motoring slot cars. Via YouTube I saw a video of how another electric train guy had cleaned the armatures of the train motor. Well, I had still been in the dark ages using a pink pearl eraser on motor armatures. This other fella had the cleanest armature i had ever seen and mentioned using a fiberglass pencil. Never heard of one. Bought these and used on the sliding switch contacts on track switches. Holy Smokes, fast and easy bright an shiny! I am motivated now to break down the train engine motors to clean them up for the first time since the 1960's!Everybody who rebuilds small electric motors or small tarnished switches needs these! Glad there are three in the pack, my wife already ran off with one.

Work great wish I had them years ago

I’ve used these for years to clean edge connectors and solder pads before soldering, as well as other tasks needing a stiff non-metallic brush. Years ago my original handle was made of metal, which I was able to squeeze the end to make the brush even stiffer, but I haven’t found an affordable replacement since. This plastic one works well but the end can’t be modified to make the brush stiffer.

Perfect for cleaning my train,especially the bushings.

Removes corrosion and polishes without being too abrasive. Good stuff! Priced fairly. Will purchase again.

Removes rust from those small paint chips (think match-head size of even smaller). Leaves a very smooth finish.
