Best Gun Solvent 2015

The Best Gun Solvent 

What is the best gun solvent out of the 10 or 20 products available?

Well…let me tell you it’s a difficult one but there are some considerations that will make it easy to pick just one gun solvent.

Most gun solvents will clean carbon, copper and lead fouling fairly well. So if you pick any one, it’ll probably clean your gun fairly well. Some clean a little faster than others but let’s not split hairs. However, there are some features found in a few gun solvents that make them a better choice.

Special Features in a Gun Solvent

Some gun solvents have a special formula that will penetrate the pores of a metal surface and “season” the metal. This so called “seasoning” works like a iron frying pan. The more you cook in it, the more it becomes non-stick. M-Pro7 Gun Cleaner works the same way. The more you clean your gun with it, the less time you will spend cleaning. M-Pro7 Gun Cleaner helps repel fouling and prevents it from adhering to a metal surface. This makes fouling very easy to remove without scrubbing for 10 minutes or so.

M-Pro7 Gun Cleaner is a solvent and not a CLP or Cleaner, Lubricant and Protectant. It strictly cleans a surface. It will remove oil, grease, lubricants, carbon, copper, lead, dirt, cosmoline and other contaminates. It cleans down to the bare metal and prepares it for lubrication or oil. You will notice it makes your gun “squeaky” clean.

M-Pro7 Gun Cleaner is non-toxic, biodegradable, colorless and odorless. So in other words it’s SAFE for humans to use. Read the label on other gun solvents before deciding what to buy. Most labels have a yellow warning that usually says, “Harmful or fatal if swallowed” or “Flammable”. Do you want to use a toxic chemical? In the house? I don’t!!!

Based on my personal experience of owning and cleaning many guns from the 50 Alaskan down to the .223 Remington and 9 mm. I have owned and shot more than 30 different guns in the past 35 years. And of course I’ve had to clean all of those guns. I’ve used many different gun solvents over this period of time and I have to say that if I had to choose just one, I would be very happy with M-Pro 7 Gun Cleaner. Of course there are several gun solvents that are very good too but M-Pro 7 has been around longer and it’s just AWESOME. And it’s inexpensive.

So why does M-Pro 7 Gun Cleaner work so well?

Number one…it’s water-based. Water-based solvents or gun cleaners are the best for emulsifying carbon and powder fouling. Water soaks into organic fouling which loosens its bond on the metal. After the water penetrates and loosens the carbon, it can easily be wiped away without brushing and scrubbing for hours. I have performed many gun solvent tests and have seen how well some solvents work and how poorly others do. And all of the water-based solvents work very well.

So how do I test gun solvents?

When I test gun solvents, I use a 1.5 x 12 x .250 piece of bare steel to act as my gun. I burn 3 or 4 smokeless powder charges on the bare steel bar and then let it cool. This provides a nice thick accumulation of carbon and other powder fouling.

Here’s the first powder charge. It’s about 45 grains of H4831 smokeless powder. I’ll ignite it and then load another charge and repeat.

Here’s the powder charge burning. It burns in open air pressure at over 850 degrees F.

After the 3rd or 4th powder charges are ignited, I can start the gun solvent test. The test is very simple yet effective. I apply a liberal amount of gun solvent on the fouling area and let it sit for 10 minutes. Then I take a fresh gun cleaning patch and try to wipe the fouling clean.

Here’s the fouling during one of the M-Pro 7 Gun Cleaner tests. Now let’s take a look at the same area after a 10 minute soak with M-Pro 7 Gun Cleaner.

The carbon fouling wipes off easily without any scrubbing, brushing or brisk wiping. Just one wipe and the carbon slides off the metal surface. M-Pro 7 gun cleaner penetrates and lifts the carbon off of the metal. Other gun solvents use harsh chemicals that are toxic and flammable. Harsh chemicals are NOT needed to clean firearms. Water-based gun solvents work the best and are totally safe for people and the environment. No harsh smells either.

What about Gun CLPs for cleaning?

There are many gun CLPs or Cleaner, Lubricant, Protectants available and some are very popular like Froglube CLP, Breakfree CLP, Archoil AR4200 and Ballistol.

So how do gun CLPs compare with M-Pro 7 Gun Cleaner?

The truth is…they are not nearly as effective as M-Pro 7 Gun Cleaner. I’ve tested most of the gun CLPs and none of them are as effective as M-Pro 7 Gun Cleaner by a long shot. CLPs are multi-role products that can multi-task but do not perform as well at cleaning as a straight water-based gun solvent. One reason is that CLPs have a lubricant or oil property that makes it difficult to penetrate carbon and powder fouling. Most CLPs sit on top of the carbon instead of penetrating it. Oils just do not make good gun solvents/cleaners.

Here’s one such CLP….Breakfree CLP. I do like Breakfree CLP but not so much as a gun solvent. In the picture, I tried to wipe the carbon fouling clean after soaking for 10 minutes but it did not. I wiped it several times but the carbon was stuck to the metal surface. I would have needed to use a nylon utility brush to get the carbon off. Of all the CLP’s Otis Bio CLP and Ballistol did clean pretty well.
