My backyard non scientific rust test - 11/22/13 07:42 PM

I wanted to conduct my own corrosion test to see which one of my lubes would protect my weapons and fishing gear the best when exposed to an ocean water salt spray. Since I had fishing reels in mind along with weapons, I wanted to have parkerized steel, brass (reel gears are often brass) and aluminum test media. The media that I had on hand that would fulfill these parameters was Federal Lake City 5.56x45 stripper clips for the parkerized steel and the brass insert inside them. I selected aluminum foil tape for the aluminum test media. The salt water spray was water dipped directly out of the Atlantic ocean, filtered through a coffee filter to remove the sand, and loaded into a spray mister.

I inspected each stripper clip and insert and determined them to be free of any rust and corrosion. The tape was a new roll and it was cut into strips similar to the length and width of the stripper clip. All media was completely degreased with 91% isopropyl alcohol and heated to 175 degrees in a toaster oven to insure that all alcohol was removed. I also used small bright steel nails to nail the stripper clips to a 1x4 board. I used used nitrile gloves and a fresh cotton swab to apply product to insure that there was no cross contamination of lubes.

Once the test began they were completely covered with a saltwater mist once each day for a total of 7 days. On day 5 it rained for approximately 30 minutes which actually washed off some of the accumulated salt crust off the test media. The photos were taken this afternoon on day eight of the test.



1) Control: No protectants applied and there is significant rusting of the parkerized steel. There is a blue green patina all over the brass insert and just a hint of aluminum oxide forming on the aluminum strip. NOTE: this aluminum strip is the only one to show any sign of corrosion.

2) Breakfree CLP liquid from 2006: This is older style Breakfree is green in color with gray PTFE. Bottle marked MIL-L-63460 and it has a National Stock Number as well. There is slight surface corrosion of the steel and brass. Nail heads are starting to rust.

3) Breakfree aerosol: Can purchased from Wal-Mart on clearance when Winchester CLP went on the shelves. This product smells just like the Breakfree I was issued in the USAF 1995-1999. Its an amber color with no visible PTFE. Visible corrosion is starting to form on the steel and brass.

4) Safariland Breakfree CLP: Product purchased new this year. Amber colored liquid and no visible PTFE. Significant rust is starting to form on the steel and there is corrosion on the brass. These results seem to fall in line with people saying that this product is not as good as it used to be.




1) Froglube paste: I applied this product while the test media was still warm as per the manufacturer recommendations. Very slight almost imperceptible freckling of rust under the word ASSY on the stripper clip. Nail heads are starting to rust a bit and slight corrosion on the brass.

2) Slip2000 EWL: Slight surface rust on the stripper clip, heavy rust on the nails, and large areas of discoloration on the brass. Rust appeared on the third day and hasn't gotten much worse since then.

3) Weapon Shield CLP: Rust forming on the stripper clip surface more than the Slip2000 and the nail heads show significant rust. Brass is discolored the same as the Slip2000. I must add that there was zero rust on the WS test media until day 5. On day 6 the corrosion cropped up and became much worse on day 7.

4) Eezox: By far the best performing product. Only a freckle of rust on the nail heads and no corrosion on the stripper clip components.

5) TW25B: Applied to level 2 condition, grease is slightly to moderately visible. Very light surface corrosion to the stripper clip and there is moderate rust on nail heads. There is salt buildup on the brass but it just wipes off clean.



1) Tufoil Gun Coat: Very light surface corrosion to the stripper clip and there is moderate rust on nail heads. Brass is discolored and starting to corrode. The parkerization did not show any rust till day 6 with slight rusting of the nails.

2) Shell Rotella T5 10w30: Nail heads covered and rust is cropping up on the stripper clip. Brass is starting to corrode.

3) Pennzoil High Mileage 5w30: Nail heads rusty and stripper clip rustier than the Rotella. Brass is starting to corrode.

NOTE: I don't use motor oil on my firearms or fishing gear but I tossed these two in the mix just to see how they fared. I know Mobil 1 is the gold standard for those who use motor oil on firearms but I didn't have any to test here.

4) ReelX: For those that don't know what ReelX is it's CorrosionX with an additional EP additive. (This is straight from their website: Starting with the revolutionary CorrosionX core technology, we added a package of extreme pressure additives specifically engineered to make your fishing reels achieve their ultimate performance. ReelX contains no wax, tar, silicone or other solids, so it will never gum-up). There is significant rust rust cropping up on the stripper clip and just a small freckling of rust on the nail heads. Brass is starting to corrode. I have this product in all my reel spool bearings.

What do you guys think? I would like some feedback and discussion.

Cliff's Notes: Eezox worked to best for me in this non scientific test.

Interesting, thanks for doing this test!! i wonder if the rust preventing results would correllate with the lubricating properties of each. I.E. how well does each lubricate? I am interested in froglube. My son has treated his AR with it, he seems to like it.

Re: My backyard non scientific rust test - 11/22/13 07:58 PM

Just a suggestion-and I realize the TW25B is a kind of grease. Could you maybe test a lithium grease and see how it performs? Some people recommend using grease on the slides of semi-autos and in the case of the Glock on the one critical lubrication area.

I have tried Eezox. I don't like it because I think it has some dangerous chemicals in it. And it has a smell that I found disagreeable and made me slightly sick.

I tried all kinds of stuff and I like to say that I wish I had my money back that I spent trying all of that stuff. In all of my testing I found a few cleaners that worked fine. Good old Hoppes No.9 or Ballistol or Hoppes Elite gun cleaner will work fine on the bore of a barrel. For a rifle barrel with copper buildup there are some more powerful cleaners. I got sick and tired looking for a decent gun oil. I am glad you tested Tufoil GunCoat because that is one I never tried and I was curious about it.

I'm really not sure but probably not. Clorox makes a heck of a short term lube but will eat steel up really quickly.

Water makes a great lubricant also. The Chinese used it maybe 1500 years ago to move some huge stones over ice using 300 people in 20 days. They only had roughly a month where they could count on ice.

Yes Eezox has 1,1,1-Trichloroethane in it which is not the safest chemical but it does make it a great cleaner. I tried the aerosol and I hated the way it smelled. The liquid version is not bad and I actually enjoy the smell. I understand what you mean, for years my dad and I used good ol' Hoppes #9 and Outers oil. Nary a speck of rust anywhere if we kept the weapons wiped down regularly. I wish I could have all the money I've spent on gun chemicals in the past 15 years. Tufoil is a great lube and a pretty good preservative but the price is cost prohibitive.

Re: My backyard non scientific rust test - 11/22/13 08:22 PM

Mystic I forgot to add that I may do another rust test and would definitely try some lithium grease. I got some Boeshield T-9 from my buddy today and want to try it out too.

Re: My backyard non scientific rust test - 11/22/13 09:36 PM

Thanks. I am pretty impressed with CorrosionX but sometimes I wonder if maybe just using lithium grease on the slides of a semi-auto is a good idea. I have some lithium grease that did not cost much and it says on the can that it can be used on guns. I got it at an auto supply shop.

Also, Hoppes sometimes recommends grease instead of oil when a gun is stored a long time. They have some grease for that purpose or at least they used to have some grease for that purpose in the past.

There are definitely cleaning products that work good enough. Now I am still evaluating CorrosionX. But so far I have never found a gun oil that really satisfied me 100%. RemOil totally dissatisfied me. Breakfree seems to be declining in quality and I didn't think it was perfect even when it was made for the military. Hoppes Elite seems kind of runny. I am just not very happy at all with gun oils.

In fact that was another reason I was considering a revolver. Mainly you just have to clean a revolver and you don't need much oil.

Re: My backyard non scientific rust test - 11/22/13 10:06 PM

Also, I have noticed different patterns of wear on my guns. On my Glock .40 there is some wear on the barrel (the black coming off a little) but the slides are in good shape. On my S&W M&P 9mm the barrel looks almost brand new even though I have fired thousands of rounds in that gun. Most of the wear is in the slide areas. So oil seems good enough for the barrel of the 9mm. But I need something better for the slide areas. Some people recommend grease for the slide areas. Actually a combination of grease and oil because a little oil can be put in the slide glide areas.

The barrel of the S&W does not seem to wear regardless if I use Hoppes Elite, CorrosionX, Breakfree or Hoppes No. 9 gun oil.

I was thinking about using the lithium grease for some guns in storage also.

It looks to me from your results that the 2006 Breakfree was definitely better than the more recent Breakfree.

It would be nice if you could test CorrosionX.

Re: My backyard non scientific rust test - 11/23/13 08:10 AM

Nice test, I like how you included different metals. Ezzox and CorrosionX are usually the top performers for me and your test pretty much confirms that. Your results are similar to the results I get when I conduct tests like these. So far I have used steel plates, nails, steel wool and sections of rebar as test media but this was a neat idea. Thanks for posting

Re: My backyard non scientific rust test - 11/23/13 04:11 PM

It is nice testing. It will help us find products that can reduce rust at least. And help us decide on products for use in preserving stored firearms.

And one of the reasons these products might be able to reduce rust in any case is because the product that prevents rust the best probably is able to stay put. So that is important for lubrication also.

Could try boeshield, corrosion x max wax and av30 for some heavier duty protection. Also lps 3

Brownells did a similar test a few years ago:

I've been very happy with Boeshield T9.

I have some Boeshield to try now but I'd have to order the other products.

Re: My backyard non scientific rust test - 11/25/13 05:57 PM

Maybe another one to try would be Hoppes Elite. It seems kind of runny however so I am guessing it would not provide too much protection.

Re: My backyard non scientific rust test - 11/25/13 10:14 PM

Thanks for taking the time to do this and for sharing the results. I have some CLP from 2000ish that I still use from time to time as well as Butch's Gun Oil. I have to say that I will check into Eezox as it seems to be a very good product.

I've never compared the two side by side, but one of the few things WD-40 is good at is short term rust protection and water displacement. Long term, I don't care for it because it turns to a sticky, varnishy mess.

Given the choice though, I'll take Boeshield.

I always include wd-40 in my tests just to have a common household standard in the test. wd-40 is a very good rust stopper but it doesn't belong anywhere near a firearm. Way too much solvent content, gums up over time and is a poor lube. About the only thing WD-40 could be used for is a very field expedient cleaner or EXTERIOR wipe down to prevent rust and displace water. Even that, I would only use it an emergency type situation.
Posted by: Mystic

Re: My backyard non scientific rust test - 11/26/13 12:50 PM

I would never use WD40 on a gun. I would use it for just a few household uses. I still remember when this woman I went bicycling with tried to lubricate her bike using WD40. The way it was squeaking anybody could tell it needed lubrication.

So far CorrosionX is working for me. Although I still have just limited time with it. Now that the winter is here I will not go shooting unless there is an unusually warm winter day. So I will find out how well CorrosionX stays on the guns in long term storage.

The CorrosionX looks like the best gun oil I have used. It is better than Breakfree, especially this free Breakfree, and Hoppes Elite, and far better than RemOil.

On my S&W M&P 9mm semi-auto any oil seems to do a good enough job on the barrel but something better is needed for the slide areas. The CorrosionX seems to be working pretty well and if I didn't have it I think I would use lithium grease on the slides.

Re: My backyard non scientific rust test - 12/03/13 12:33 AM

Today I began another rust test to include:
1) Eezox (since it did the best in my last experiment)
2) Boeshield T-9
3) WD-40
4) Muscle Products PL-10 lithium complex grease
5) Pro-Shot 1 Step
6) Safariland Breakfree CLP (since it did so poorly last time rechecked to see if it's
performance last time was come sort of anomaly)

Check back for an update in a week.

How about G96 spray? I've used it for years for light cleaning and for wipe down of rifles and handguns. Smells good too!
I've never had any surface or bore rust from long term guns stored in the closet.

I'd love to try some but none of the gun stores around here sells it. Send me some and I'll try it.

Re: My backyard non scientific rust test - 12/06/13 02:18 PM

Interesting! I had been wondering why the new CLP looks different...
That EEZOX mopped the floor with them, is the catch its highly carcenogenic? Or is that just the aerosal version?

I have seen at least two different formulations of Breakfree CLP since the mid 1990's.

Both the liquid and aerosol versions of Eezox contains Trichloroethylene (CAS NO: 79-016). Since the aerosol version atomizes a bit when it's sprayed it would theoretically be easier to inhale the Trichloroethylene. The liquid version that I use doesn't have a bad smell and I have no problems using it indoors.

Backyard rust test part 2 - 12/12/13 08:22 PM

Here is the second backyard non scientific rust I conducted using some popular products. If you missed the first one it's here.

The testing parameters are the same except I didn't use any aluminum test media this time. I sprayed these stripper clips with Atlantic ocean water once a day for seven days. It rained on three of these days and for over eight hours on one day. I have been really busy working some overtime so I took this photo on the tenth day after the experiment began.



1) Control: Metal clip rusted over and corrosion starting to form on brass insert.

2) Eezox: Metal clip had two very small freckles of rust (one was between the S&Y on ASSY stamped on it) that I was able to wipe off with my finger without pitting. There was some discoloration on the brass insert which were salt deposits.

3) Boeshield T-9: Nail heads were rusted over and there was a small amount of rust forming on the left side of the metal clip. The Brass insert had salt deposits which wiped away and the rust from the nail stained it's left side.

4) WD-40: Maybe those who say that this is a good rust preventative will look at this. It is rusted almost as bad as the control and I feel that WD-40 has no business on a firearm to begin with.

5) Pro-Shot 1 Step: This is marketed as an all in one CLP. There was heavy rusting on the stripper clip and the brass insert is starting to corrode.

6) Safariland Breakfree CLP. On my last test this did worse than the old style CLP so I retested it again. Same results as last time.

7) Muscle Products PL-10 grease: I tested this because some of you use a lithium complex grease and asked me to test one. There was a little rust starting to form on the top left of the stripper clip and on the nail heads. The discoloration on the brass insert just rubbed off with my finger.

Like the first test I conducted, Eezox is still the best performing product at keeping rust at bay.

Well because I have the ReelX on hand and I don't have regular CorrosionX. The only difference between the two is that ReelX has an EP additive that Corrosionx doesn't have. The inhibitor packages are the same on both the products per a conversation I had when I called the company.

Re: Backyard rust test part 2 - 12/13/13 06:18 AM

One thing I forgot to mention is when I sprayed water on these, all the products except Eezox beaded up water. The water seemed to partially sheet off the Eezox treated metal.

Re: Backyard rust test part 2 - 12/13/13 06:34 AM

Somehow I still think the way Reel-X and Corrosion-X behave in real life are different. I mean I trust that they have the same CI's, but somehow the AW comes into play.

Thanks again Buzzsaw!

If I do another test I could pick this up at Walmart and and try it.
