Review: Amazing product - This stuff is amazing. I blued several of my tools completely and did some touch ups. It works in 10-15 seconds (under one minute). The trick is to to clean the surface very well to remove any grease with acetone or alcohol. Also, I got a better result by using a wire brush vs recommended #0 steel wool after bluing. The black coating is basically also a type of rust and it is porous and to prevent regular rusting you need to apply any oil or wax as a rust inhibitors after bluing which will be absorbed and retained by the black coating creating a barrier for regular rust.
Review: Works well. - Did its job well for me. When done right will give a proper cold blue finish. Remember to always pour the needed amount out into a separate container when using it in order to not contaminate the main bottle. The lowest price for quality cold blue when I bought it. No complaints.

## Features

- Absolutely no after-rust
- Ease of application and remarkably superior results
- With Oxpho-Blue, all you need do in most cases, is dampen a piece of cotton flannel and give the area a good rubbing

### ⭐⭐⭐⭐⭐ Cold blueing with brownell's oxfro
*by S***W on March 5, 2025*

I have done 3 22cal rifles so far ranging in age from 85 years to 54 years old. All have came out excellent, the coverage was a dark uniform color and was easy to apply. I did slightly heat the barrel with heat gun and burnished with 0000 steel wool between coats.
