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

I do a lot of SMD rework and find these really handy for cleaning up copper, pads and lands. I mostly use the fiberglass brush, but the others find occasional use. Very nice set. 5 stars.

Was looking to replace fiberglass pen from as far back as Radio Shack. Liked the pen function so decided on this set. Metals (brass and steel) are too thin to be practical.

I bought these on recommendation. They do work, but I was expecting more. I guess it depends on what kind of tarnish/rust they are used on. It would have been nice if they had labeled the actual brushes instead of just the pouch. I ended up using a label maker to mark them.

The fiberglass one is the only one I have used so far. Perfect for cleaning enameling after getting fingerprints on it and before putting on another layer of glass enamel.

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

I use these to repair circuit boards. Nothing else will do the jobs of removing foreign objects, old flux etc.

The printing telling which brush is which is on the case, not on the brush, which is more annoying than you might think. Product is fine otherwise.

I got this because I had 2 rusted chips on my jeep and the recommendation was to use the fiberglass pen to clear the rust. I ended up getting the jeep oem touch up kit and the scrub tip on that combined with an exacto blade tip did a far better job than this one. If you’re getting it for some other purpose I’m sure it does fine but if you’re trying to clear rust from a paint chip then save the money

They came apart before I used them the first time.

I got these to repair dings and dents on my cars paint jobs but I cant say they work. I watched a lot of videos on how to use them but either Im not a pro, or they just need a professional hand. Would not recommend at all unless you think you can figure it out.
