Remove old bluing

This may seem like the opposite of our title but when rebluing a gun, you have to remove the blue first. If you don’t remove the old one, all the space of the gun won’t be blued perfectly. A slight presence of old rust will hinder your process of rust proof bluing.

Take a perfect shot with the abrasive blasting. No other process can beat this universal process. but it is my duty to acknowledge you about other processes.

Before that let’s know about the universal process-

Abrasive blasting

Right after you’ve taken the old blue off, a layer of rust will show up. So, how to remove rust from guns without grinders?

Well, here the only thing you need to perform this method is grit paper. With the simple grit paper, you can remove all the old blue perfectly.

But it will be better if you use steel wool and gun oil before using grit paper. These will help you to remove scratch, rust or pit. Just soak the wool with the gun oil and use that. Proceeding further, it will make the surface prepared for complete rust bluing a gun.

Remember one thing that grit paper size differ the finishing of your work. It will be easy to get a good finishing if the grit paper size is high. At first start with 400 grit, and then one round again apply steel wool with oil. Then use 600 grit for finishing.

After all of this, your gun will be free from previous old blue and also from harmful elements.

Using chemical paint stripper

You can use this effective and easy method but this process takes too much time. If you have no problem with the time and you are dealing with two or three guns then you can apply this method using a gun bluing solution.

At first, you have to apply chemical stripe by the brush. Don’t apply the too much thick layer. It is better to apply a thin layer. Then you have to wait. You have to wait for a minimum of several hours. I have also seen that many people stay for a day at all to just let it sit perfectly on the metal. Then clear the surface using soft steel wool, nylon brush, etc. Clear it until the metal comes into its original look.

Blue removers

There are so many blue removers in the market. You can use those types too. Select the blue remover by giving a look at the description and also to your budget.

Degreasing

After removing old blue you must remove the oil, grease, or other unwanted droplets that can ruin your gun. And to remove this there are few types of solutions in the market. They are known as the chemical cleaner. They contain normally sodium metasilicate. You can also use the commercial detergent which contains sodium triphosphate. And there are some people I know who use acetone and sometimes I also use that. And moreover, you can also use denatured alcohol. But I always suggest people use nail polish remover which is actually acetone. It fully cleans the metal and removes any kind of oil that is stuck into the gun.

Mix the solution into the water. Then bath the gun into that mixture. Some solutions may need to heat up and some not. Before doing so be sure about that.

Rinsing

You need to rinse the metal after degreasing. You can pour hot water on the metal and that will remove all the existing solutions over the metal. You shouldn’t rise more than two or three minutes.
