8 Pieces Scratch Brush Pen Set, Pen Style Prep Sanding Brush With Steel, Brass, Fiberglass, Nylon Replacement Tips for Jewelry, Watch, Coin Cleaning, Electronic Applications, Auto Body Work

It is surprisingly difficult to find fiberglass scratch brushes for electronics. I have been using this for a week or so and the fiberglass cleans traces well and I find myself using the nylon and brass more than I expected. The nylon is good for cleaning solder joints where you need something firmer to get old flux off or baked on crud. This set came with replacement brushes, I have no idea if the bodies will last that long. As mentioned in other reviews the bodies are a little on the cheap side. For the price it wouldnt be painful if I had to buy a new set every year. It would be nice if someone would make a really nice sturdy set, something you would keep for a lifetime. One of my friends who does electronic repair has a 3/4 fiberglass scratch brush and he said it was really expensive. I couldnt find one so this will do.

Works as described no issues

Had a hard time finding small wire brushes that came off the tip rather than the side. The smallness of these brushes make it perfect for cleaning and reviving my lighter collection. An essential tool for restoration. Not for big heavy jobs.

This was exactly as expected and works well.

I really only wanted this for the brass and fiberglass tools, but the extra inserts were worth buying the set. This allows me to get the final detail done on ancient coins before waxing, and allows for more precise cleaning.

They work great.

There okay. You’ll need to trim & clean them to get the right finish you’re looking for if you’re trying to remove CA glue from a plastic model.

No instructions. Tips seem hard to change, and unsure as no instructions.

I didn’t know these scratch, sanding, cleanup pens existed. Wow was I missing out. They get into tiny spaces and are great for prepping something to solder, for sanding a tiny spot to paint, or taking a little tarnish off items.

I have used a these a few times and they done the job I expected of them. They definitely helped reaching areas that I could reach with my fingers.
