Review on 🔧 Premium Topbuti 15 Pcs Mini Brass Wire Brush Set - Excellent for Welding Slag Rust & Cleaning, Wire Bristle Scratch Brush Set with Curved Handles (Brass) by Andrew Jones

I bought these at my wood shop mainly to clean nozzles and blades. The brass is soft enough not to damage the edges, but still offers enough rigidity to knock out dirt. They are similar to those you typically see at places like Harbor Freight. Cheap plastic handles but so far I haven't noticed the bristles falling off. I usually get quite a few uses from each brush, and at this price point I don't have to fuss too much about throwing it away when it's too mangled. These will likely last the rest of your life.
