Pixiss Scratch Brush Pen Set With Replacement Tips, Fiberglass, Steel, Brass, Nylon, 5-inches Pen Style Prep Sanding Brush 4-Pack For Corrosion, Rust, Jewelry, Circuit Boards and Auto Body Work

Got this to clean up an restoration project. After using to clean up the original hardware (which had been soaked in cleaner) the 2 I used fell apart after 1 use.

Received these today. Ordered them to clean up an old flashlight that we love and cant replace. Started with the Brass Wire. Within the first 5 seconds it was coming apart. The wires where falling out and pushing back into the handle. At first I was able to get them to come back out. But after 3 minutes or so, they were back up in the handle and would not move. Next was the Nylon Bristle. It came apart in my hand while I was removing it from the package. I was able to get it to snap back together for a few minutes use before it came apart again. Needless to say, the two brushes I used are an EPIC FAIL! Not sure about the Steel Wire and Fiber Bristle. I did not use them. Writing them off as a learning experience. Do yourself a favor, keep looking.

Works great to erase little errors in woodburning. Can pull out paint as well.

Maybe the steel and brass pens are.. Ok.. Kinda.. But the fiberglass does nothing, Nothing at all. Wont even scratch a PCB. Youll regret the purchase if PCB solder mask removal is at all why you are purchasing,. GOOD LUCK.

works great but wears down fast

God quality and the versatility is excellent for my usage

Nice set. I havent used them yet, but glad to have when I need them.

Great little brushes

Got this as a supplement to my other scratch brushes and they dont scratch anything all. Even the metal brushes dont remove solder mask from PCBs.

Seems like every battery operated device I own eventually has bad caking or corrosion at the contacts, and I can start the cleanup with the softest scratch brush and work my way up to the steel brush whenever needed.
