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 is great for cleaning electrical contacts and small connectors found in home theater/audio systems.

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.

Needed a fiberglass pen to clean some corrosion off a circuit board and it worked just right! Thanks again.

I use mine on my modeling/sculpting bench. They work great, and its wonderful to be able to retract and protect the bristles when not in use.

I have now tried all 4 pens, even though I truly only needed the fiberglass. The brass and steel pens hold up fine, but its not a great idea to just start scratching away at things with metal. The nylon brush is useless. You might as well get a $1 kids paint brush, because you will not scratch away anything with the soft edges of this nylon. Finally, the fiberglass pen. I was trying to remove about a 1in x 0.5in section of circuit board coating and it did NOTHING to remove that coating. By the time I scraped away the top coat with a separate, metal spudger, I went back to the fiberglass to polish. POOF. The whole section tried to disappear into the pen. Fished It out with tweezers and clamped the holding section so tight I could barely get the pen tip back on. First round back at it, a little resistance then the whole thing disappeared again. If youre going to need the fiberglass specifically, DO NOT BUY THIS PACKAGE. Spend a few extra dollars and get a quality product that will last AT LEAST a single use.

Good: The pen brushes are made well and have a smooth feed mechanism that locks in place. Bad: The carry pouch has a label for each pen (steel, brass, fiber, nylon); however, there is no such label on the pens themselves! One star deducted for this.

Fiberglass scratch pen was way softer than I was expecting, and the wire brushed splayed out really quick.

They looked great. Concept is wonderful, but quality: epic fail! Each one them fell apart within moments of the first use. The actual handles are not glued together properly. Poor control of brushes...they just fall out. The best part about the purchase was the plastic pouch they came in. It was the only thing that did not end up in the rubbish!

These little brushes are retractable which is helpful to control the stiffness of the bristles, that said the bristles in the metal brushes are a little sparse, but work for what I want them for. I am satisfied with the price and quality.
