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

This has a nice variety of bushes of different materials. I never used a product like this before and may have had too high an expectation for its effectiveness. It helped but didnt do the job I had hoped for. It is worth the money to have on hand.

Great for the money

Use them to clean our Pax 3 & grinders. Works great because they are adjustable so it can be stiff or soft depending on what youre cleaning.

First time looking for something like this to clean hard to reach rust on tools. Ive only used the metal ones so far, and they work about as well as fine steel wool work if I could get it in there, except it takes about 10 times longer. The tip just feel out, because the mechanism that holds it in place is simply a short piece of piping that it pops into. Hopefully Ill figure out where I can find a similar tool grade tool soon. Update, after cleaning over 100 tools in the last month, using various different steel brushes, several very well made and expensive. This tool works better at certain things than even the best stainless steel $20+ single brushes. You cant move it however you want to, but once I figured out to use it in back in forth strokes, no longer than 1/4 inch, it works where others cannot. It also helps focus the brushing right where the rust is. Upgrading the review to a 5.

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.

These are well made and have lots of uses, but I was hoping the fiberglass pen had stiffer bristles like the one I bought years ago at a hardware store.

A must have for any customizer in the diecast hobby. I actually use all 4 and work perfect

I ordered the whole set just to get my hands on the fiberglass scratch brush for electrical contacts. I had ONE that I used for at least 10 years but I had to leave it behind at work when I retired. This set of 4 various-fibered brushes looks O.K., but I eagerly got out the glass bristle one and twisted out a little stiff bit, and went at a tiny rust spot on a knife blade. Bloop! The fibers disappeared up into the body of the pen. Turned the advancing knob on the top. Nope. Nothing. Took the end off and there was the bundle of glass fiber. It wouldnt move except for a tiny bit and turning the knob did nothing. So, I guess thats what I have. Nothing. Just a broken pen and 3 more types for which I have no use.

Works just like I needed them to
