Best Gun Cleaner Spray

So what’s the best gun cleaner spray?

I have tested and used many and I do mean MANY gun cleaners in the past 30 years.  There are 3 sprays that stand out from the crowd of gun cleaners and they are:

  1. M-Pro7 Gun Cleaner
  2. Mil-Comm MC25 Premium Weapon Cleaner
  3. Hoppe’s Elite Gun Cleaner

All 3 of these come in a spray bottle that makes it super easy to apply. Here are the reasons why I rate these 3 as the best gun cleaner sprays.

  1. Excellent cleaning ability
  2. Non Toxic
  3. No strong smell
  4. Does not stain
  5. Easy spray bottle
  6. Biodegradable
  7. Reasonably priced
  8. Safe on metal and synthetics
  9. Safe for any type bluing

BreakFree CLP Corrosion Test 2

Is BreakFree CLP a good protectant for guns?

The only way to know for sure is to test it…so here we go.

My corrosion test is simple yet effective. I take pieces of steel bar, clean them and then apply an oil or CLP to them. I let them sit outside in the Arizona heat and spray them with water 3 or 4 times per week. I record how long it takes for the metal to rust. The longer it takes to rust, the better the protective properties of the gun oil or CLP.

Here’s the Breakfree CLP and 2 pieces of cold rolled steel. One piece will be heated to 100 degrees and the other left at ambient temperature (85 degrees). The reason for the heating is to determine if oil penetrates better if the metal is hot. Does it really seep into the metal pores?

So how do I heat up the metal test material? I use a heat gun and then a temperature gun to measure the temperature.

I’m applying 2 drop of Breakfree CLP to the unheated metal bar. I will spread the CLP evenly with a cleaning patch.

Here’s a closeup.

Here’s the temperature of the 2nd metal bar. It reads 100 degrees. Now I’ll apply the Breakfree CLP to it.

2 drops of Breakfree CLP and then spread it evenly.

Here’s the testing area where the metal bars will stay until they rust. You can see the water spray bottle in the background.

Here’s one bar with a dousing of water. It beads up very well.

Here’s the 2nd metal bar after spraying it with water. Nice beads too.

Now let’s see what happens in the next 7 days. Stay tuned.

Day 4 – Breakfree CLP Corrosion Test

Here are the 2 Breakfree CLP treated test samples.

Unheated sample – no corrosion

Heated sample – No Corrosion

Now let’s wet them again.

The water still beads on the metal. That’s a good sign that the Breakfree is still protecting the metal.

So far, Breakfree CLP has done a fantastic job at protecting bare metal against the elements…water and heat.

*** Remember this is an extreme corrosion test. Most guns do not get sprayed with water several times per week.

Breakfree CLP Corrosion Test – 14 days

You can see some rust on the left edge and top left edge. Let’s take a closer look.

There you have it…RUST. The heat treated sample (on the left) has more rust than the un-heated sample.

It most likely started on the edges where the Breakfree CLP was not applied that well. The rest of the metal is pretty much corrosion free. So Breakfree CLP prevented corrosion for 14 days while being exposed to water and heat. That’s pretty good considering you probably won’t put your guns through the same kind of treatment. Under normal conditions, Breakfree CLP will do a great job of preventing corrosion. Another note…apply Breakfree CLP at room temperature and not on hot firearms. It seems to protect the metal better.

Remington Rem Oil Corrosion Test

Is Remington’s Rem Oil a good gun protectant or corrosion inhibitor?

Let’s put it to the test and see how it performs.

This corrosion test is very simple…I apply Rem Oil to a steel bar and then leave it out in the elements…rain and shine. Actually I create the rain via a water spray bottle.

Here’s the steel bar with 3 sections marked off by the blue masking tape. The large 1st section on the right is the heated application(104 degrees), the middle section is room temperature (85 degrees) and the last section on the far left is untreated or bare metal.

The first section was heated to 135 degrees initially but it proved to be too hot for Rem Oil. The Rem Oil sizzled and burned off. I let the metal cool to 104 degrees and then applied the Rem Oil. The reason for the heating is to see if the oil penetrates better on warm metal.

The middle section was 84 degrees when the Rem Oil was applied. The 3rd section on the far left was left untreated.

On the first and 3rd day, I sprayed water on the entire steel bar and left it outside. The temperature range was 68 – 95 degrees with low humidity.

Let’s take a look at the 3 sections after 5 days.

104 degree heated and treated with Rem Oil

You can see on this closeup view that there is rust. Now let’s look at the 2nd section where the Rem Oil was applied at room temperature.

84 degrees and treated with Rem Oil

You can see a few spots of rust on this section also but less than the 1st section where the metal was heated.

And now the untreated section…

There is some serious rust on the untreated section. There is no doubt that Rem Oil does provide some protection against corrosion and it works best if applied to room temperature metal.

Best Gun Oil for the AR-15 Rifle

Is there a best gun oil for the AR-15 rifle?

I think so. The AR-15 rifle has fairly tight tolerance and so you need a thinner oil that can get into and stay in tight places. I have had 2 AR-15’s (Stag Arms T2 and Smith & Wesson M&P 15) and tried many gun oils on them. Both of these rifles were 100% reliable with zero failures regardless of lubricant.

So what gun oil did I like and use? I first used BreakFree CLP for about a year and then switched to Hoppe’s No 9 Synthetic Blend Lubricating Oil. The reason I switched was not because BreakFree CLP failed but because I physically tested the 2 lubricants with 2 pieces of metal and the Hoppe’s No 9 Synthetic Blend gun oil felt a lot more slipperier. Synthetic oils reduce friction and wear more than conventional oils.

I want to say one more thing about firearm lubrication and that is that most gun oils are better than CLP’s at lubrication and synthetic oils are better than traditional petroleum oils. If you’re looking for a dry lubricant, Hornady One Shot is excellent. It is extremely slippery and easy to apply.

Clean Guns While Still Warm or Hot?

Should you clean your guns while they are still warm/hot from shooting?

While fouling may be easier to remove when guns are warm or hot, the higher temperature may cause your gun cleaner to evaporate before it has a chance to soak into the fouling/carbon. Gun cleaner soak/penetration is much more important in gun cleaning. If the gun cleaner does not penetrate the layers of carbon and powder residue, it will not remove it.

The ideal gun cleaning scenario is to submerge the barrel and action in gun cleaner at a temperature of about 90-95 degrees for an extended period of time(hours).

2 critical aspects of gun cleaning will make or break it.

  1. Use a gun cleaner that is water based or with a low viscosity(not oil or alcohol or acetone based).
  2. Soak time of 10 minutes, while wet.

Use Gun Oil on Hot Guns?

So there are some discussions about cleaning guns while they are still hot and also using gun oil when the metal is still warm/hot.

Is there any possible benefit?

I’m trying to test the gun oil on warm/hot metal scenario right now to see if there is more penetration and therefore better protection and lubrication.

I did a preliminary test with Remington Rem oil and a steel bar heated to 135 degrees. I used a heat gun to heat the steel bar. I then placed a few drops of Rem Oil on the 135 degree steel bar. The Rem Oil boiled/sizzled off. So 135 degrees is too hot for Rem Oil. I then tried it at 124 degrees. It boiled off again.

I let the steel cool off to about 104 degrees and then applied a few more drops of Rem Oil. It did not boil off or sizzle like before. I then spread it evenly with a few patches. I’m going to see how well it resists corrosion via a daily water spray. I’ll compare it to a section of steel that was not heated, with Rem Oil being applied in the same manner. My goal is to see if the heated application resists corrosion longer than the non-heated application.

I will perform a lubrication test also…as soon as I get the steel bar stock.

Can You Clean a Gun with Soap and Water?

Here’s a great question: “Can you clean your gun with just soap and water?”

The answer might surprise you.

The short answer is YES.

Soap and water will remove carbon and powder fouling but not so much for copper and lead. Always remember to let the soap and water solution soak for about 5-10 minutes. I have used water and Dawn dish soap successfully. Water is absorbed by powder residue and carbon which loosens it, making it wipe away easily. Just remember to dry all metal parts thoroughly and then oil. This is how you have to clean guns that have fired corrosive ammo in them or black powder.

This is why some of the water based gun cleaners work so well like Slip2000 725 Gun Cleaner and Mil Comm MC25. I think M-Pro7 Gun Cleaner is also water based.

Slip2000 725 Gun Cleaner Test

Slip2000 725 Gun Cleaner is a non-toxic water-based cleaner and degreaser. I have used it in the past on my Glocks and it worked really well but I never really new how well, so I decided to test it.

I use a simple test for gun cleaners. It’s composed of a metal plate or bar, smokeless powder and a gun cleaner. I burn several charges of gun powder on top of the metal plate and then apply a gun cleaner to see how well it removes the fouling and residue.

Let’s take a look at the gun cleaner test setup.

Here’s the typical gun cleaner test setup/equipment. The first thing I do is clean the test bed which is the aluminum plate/bar. Then I pour a 50 grain charge of H4831 smokeless powder on top and ignite it.

Hodgdon’s H4831 is a slow burning powder, so it’s pretty safe to experiment with.

Here’s the 1st powder charge. I’ll ignite this one and then do it all over again 2 more times. This provides a good amount of fouling that is pretty hard to remove easily.

I use a long grill type lighter to ignite the powder.

You can see how slow this powder burns. It takes about 3 seconds to burn.

Here’s the result of 3 charges of H4831. There’s a pile of carbon that is stuck to the metal test media. Let’s see how well Slip2000 725 gun cleaner removes this.

I’m applying the 725 gun cleaner to the fouling, spraying it on very heavily and then letting it sit for 10 minutes. This is the key to cleaning carbon fouling. You have to let it SOAK.

Here’s the fouling soaking. I’ll try wiping it clean after 10 minutes.

The fouling “pushed” to the left easily when I used the cleaning patch to wipe the area. The Slip2000 725 gun cleaner loosened the fouling, so it could be wiped off easily.

There you have it…nice and clean. Slip2000 725 gun cleaner is AWESOME. It’s also totally non-toxic and safe to use indoors. There is little to no odor and it’s clear. Great product!! If you want to try it out, here is a link….Slip2000 725 Gun Cleaner/Degreaser at


Hoppe’s Black Gun Cleaner – New 2017

Hoppe’s Black High Performance Gun Cleaner is a brand new product for 2017. It was formulated for high round firearms like the AK’s, AR’s and other semi auto rifles and handguns.

This high performance gun cleaner removes heavy carbon and powder fouling from bores and actions easily. It’s safe for all barrels and actions. It works best when you soak the bore using wet patches or a boresnake and then let it sit for 10 minutes. Then patch until clean.

I just ordered the Hoppe’s Black Gun Oil and Gun Cleaner to test. I’ll post the test results as soon as they’re complete. I tested other Hoppe’s gun cleaners like Elite and No. 9 synthetic blend bore cleaner with excellent results. I would think this gun cleaner would do no worse.
