Some of you will recognize these brushes immediately – they’re Otis cleaning brushes. They’re primarily made for cleaning firearm parts, but can be used on all kinds of other things.
The bristle coloring is important, because it indicates the stiffness of the bristles.
White: The white nylon brush is the softest.
Blue: The blue brush is a little more aggressive, while still being made from nylon.
Brass: The brass-bristled brush is stiffest and more aggressive.
Each brush has a large head for cleaning and scrubbing wider areas, and a smaller head for cleaning smaller parts or reaching in tight spaces.
Otis says the brushes can be used for all kinds of applications:
These versatile brushes have many uses from automobile detailing, boats, golf equipment, battery terminals, camping, grout, jewelry, wood working and more.
I bought my first set a while ago (my Amazon order history says 2013), and they have come in very handy for precision cleaning tasks.
I’ll bring them out for all kinds of random cleaning tasks, but I mainly use my brushes to clean circuit boards and components that will be soldered, small parts that are being glued or painted, and for cleaning chips from threaded parts.
They’re made in the USA.
Price: $10-12 for the 3-pack, less if you buy bulk quantities
