The Megacast Fiberglass Scratch Brush Pen has proven to be an invaluable tool for maintaining my HO scale model train motors. It’s compact, precise, and incredibly effective at cleaning delicate components without causing damage. The fiberglass bristles are the perfect balance between stiffness and gentleness, allowing me to clean off grime, oxidation, and buildup from motor contacts and other small parts with precision. The adjustable tip is a standout feature—it lets me control the amount of bristle exposed, which is great for working on different surfaces and levels of dirt. I was initially concerned about durability, but the bristles have held up well after several cleaning sessions. Replacement refills are also easy to find, ensuring that the tool remains useful for a long time. What I appreciate most is how this pen allows me to reach tight spaces and crevices in the motors that would be impossible with traditional brushes. It’s a must-have for anyone serious about maintaining their model trains or other intricate hobbies. If you’re looking for a reliable and effective cleaning tool for small, detailed work, the Megacast Fiberglass Scratch Brush Pen is an excellent choice. It’s easy to use, affordable, and delivers great results. Highly recommended for hobbyists and professionals alike!

10/10

I'm an electronic tech who restores a lot of vintage audio equipment. These are great for cleaning the crud off of connectors and plugs. If you do this kind of work these are a must-have. The price is certainly right too.

Using for cleaning H0 scale train wheels, commutatators and wipers. Does a good job
