Otis Technology3 Pack AP Brushes (Nylon/Blue Nylon/Bronze)

These are excellent brushes. Even the white (softest) brush is stiffer than a typical toothbrush. White brush works well for general wiping not parts that don't have much gunk built up. Blue brush actually works great for scrubbing most things without damaging the blueing or scratching anything. And the bronze brush is as you'd expect: good for scrubbing the feed ramp, firing pin, etc.I also really like the combination of big and small brushes. Small brushes do a much better job getting into corners, slide rails and other tight spots than the big brush.All are holding up well so far. I definitely should have gotten these sooner

I actually bought these to clean the calcium/mineral deposits off of the Warm Mist Humidifier in my daughter's room. We have very hard water in my area and a warm mist humidifier builds up deposits quickly.I use the blue one mostly as it has a hard, non-abrasive bristle. The copper gets used for tougher deposits. I save the white one for my pistol cleaning. The size of each brush is good and can get most of the small spots on a Glock. The price was good and they've lasted a while, so they get 5-Stars for now. These worked great at removing residue from a shotgun I was cleaning. Only issue, and this isn't really a complaint so much as a nitpick, is the bristles on the bronze brush are really easy to bend in all sorts of weird angles. I don't expect I'll be using the bronze brush or if I do I'll have to replace it earlier than I expected. Still, definitely worth the money. These brushes have been a great addition to my firearm cleaning supplies. They are holding up very well and perform the job better than I had expected. Previously, I was just using a toothbrush but found it tough to reach certain parts of my weapon. These brushes are thinner than a toothbrush and fit easily in places I wasn't able to reach before. Having 3 different brushes allows me to use the harder bristles, when needed and the softer, when needed. These are a great buy for the price.

Great brushes, just the right size for my purpose. Much more durable than repurposing old toothbrushes. I used the nylon brush to clean mineral residue off of Moen oil rubbed bronze shower fixtures with a vinegar and baking powder solution. Brushes provide just enough abrasion without damaging the finish. I also use the brass brush to clean up internal metal parts on a shower assembly.

Really nice brushes... I love they way they have double sides, one with full brush and the other one for fine cleaning (like pistols slide inside rail).Really worth it for the price! edit: More than two years later the same brushes are still doing a great job. Cleaned my pistols and rifles around a hundred times and they are still working great. No sign of fatigue on blue and transparent nylon brushes and only a little on the brass one. These are awesome brushes!

I needed to clean some tight corners and edges on plastic parts and the small end of the white brush was perfect. I've also used the brass brush to attack some nasty stuff dried into my carpet. Brushes are straightforward but you'll know if you have a need for these and they do the job well.
