Review on 🔍 Excelta Scratch Straight Fiberglass Brushes by Matthew Outlaw

I use this to remove soot and dirt from electrical wires after a fire for inspection. It is made by tying together very thin strands of fiberglass. There are other similar brushes, but they are much smaller in diameter. The large size of the brush makes cleaning conductors and contacts much easier. This is my second. Very helpful.
