Economy Scratch Brush, Fiberglass, 4-1/2 Inches | BRS-294.50

Worked like a charm on my scuffed up Titanium field watch but when trying to work with on my stainless Steel cased watches it took a little more "elbow grease" to achieve the same results.Definitely worth getting again though as the fiberglass pen did exactly what I needed it to do.

My smoke detector was beeping due to low battery. I tried putting in a new battery and re-setting, but it still beeped. There was some corrosion on the battery contacts on my smoke detector. I bought this brush to clean the contacts, now the smoke detector is working again. My order was fulfilled quickly, the brush worked great, and it's good to have it for future situations.

This pen brush is amazing and I've probably only used less than an 1/8" of the fiberglass. It has cleaned up contacts so well it makes the connection like new and the signal is present unlike before. Worth buying!

I bought this to clear the contacts off and old circuit board! It accomplished that job flawlessly!The build quality of the casing around the fiberglass strands is to be desired... There weren't directions so I just had to play with it a second to figure out how to extend the brush, but by doing so the top pop off and I don't think that was suppose to happen. Though I got he job done that I needed to and that's what counts! Definitely should wear gloves when using these unless you like getting fiberglass in your skin!!

This lasts a long time for my use, which is cleaning model train wheels and contact points. Says it's refillable but for the price you can just get a new one. Holds up well. Little bulky in the hand when working on small tedious jobs.. but I can deal with that.

I was looking for a scratch brush to clean Edge connectors on electronic circuit boards. I refurbish antique electronic equipment and some of the electrical contacts I come across are badly tarnished and corroded. This scratch brush did the trick! It cleaned contact pads nicely. It was an inexpensive and does what it it is designed to do. It's small enough to fit and my shirt pocket, morning my toolbox.

A cap would have been nice, since fragments of fiberglass are really annoying if they get in your skin. I use this to polish up corroded battery terminals while holding it deep in a trash can to catch the tiny sharps. Its predecessor that lasted for years had a cap, but one day the bundle of fiberglass fell out and I did not want to touch it.

I bought 1 and liked it so much that I purchased another. One in my garage and one in the house. Excellent for cleaning corroded contacts in electronic products that are hard to reach. I see it being a very useful tool to have around the house and garage as I can envision any number of potential uses when nothing else does the job as quickly and as well. Highly Recommended.

Cumple bien con su función, el cepillado que genera es muy fino. Aunque no lo usaría realmente para quitar rayones de un reloj, a menos que puedas cepillar completamente toda la superficie de la pieza.

These are great for cleaning low voltage electrical points like in model trains

Used this to fix small rock chips in car paint. It worked well enough but I wish the nub was about half the size.

The concept is brilliant but execution is poor. This worked well the first 2 times I used it to remove leaked battery acid from a battery compartment. The 3rd time however, required a little more pressure and the fibreglass just dissolved to bits and the black pen top broke off. I'd look for better quality and won't purchase this again.

Good product well made
