Does WD-40 get gummy?

I've been slowly cleaning my stuff after several years of non-use. Yesterday, I cracked open a double barrel and it was stiff. I found gummy residue where the barrels and action meet and also on the hinge. I don't know if it was from some prior gun grease or from some WD-40 that was sprayed on years ago. I know...I know, I took the lazy man's route in years past.

Comments?

WD-40 SUCKS! Always has always will.

I use Break Free.

WD-40 is for cleaning not storage.

Rig-Rags with Rig grease works great too.

Nope. WD-40 evaporates quickly to almost nothingness. Only use WD-40 for water displacement!

Do a little home experiement. spray some WD 40 on some metal and let it sit undisturbed for about a week. Then take a clean white cloth and wipe the metal. Decide for yourself if you want to use it on your gun. If you have pets or dust at home I'll bet you won't.

From what I have read, WD-40 will ruin primers. If you want your ammo to go bang, keep WD-40 away from ammo. And keep it away from reloading components. I don't use it in or near my guns.

Sounds nasty. The other thing about WD40 is that it's mostly propellant, propane propellant at that. Highly explosive when exposed to places where you might want to use it... like engine compartments. A far better item to get electrical items dried out is LPS 1. There are also several other grades of LPS for different jobs.

OK...how about Kroil? Some of these guns haven't been used in 20 years and might not be used for another 20. I once used gun grease for long term storage, but that was a problem unto itself.

Kroil is GREAT for it's intended purpose but short term and long term storage is not it.

If they are going to go untouched for 20 years, you need cosmolene!

For long term storage use Breakfree Collector or Rig. Store long guns muzzle down to keep oil from running into your buttstock and weakening the wood.
WD-40 has no place near firearms.
Kroil is probably the best penetrating oil in the world. Great for removing surface rust, loosening stuck threads and cleaning carbon from bores, but it is a lousy lubricant and does little to protect metal.

yah i didnot say use for a lube and not a CLEANER . i use it and its been the only thing that works and its never hurt the wood it gets so damp at the cabin that the gun gets a film of water on it and never rusts :cannon: PS. IT IS WHAT IT IS!!

In the continuing saga, I found more gummy residue in a Win 92. More to go.

Anyway, I was thinking of a light lithium grease...just a light coat. But I've seen that harder too...in 30-40 years on old car parts.

WD40 is not very good for what you're paying for it. Several products out there that will do anything it can plus more with less negative side effects.

WD-40 for lube? That's just funny.
It's basicly kerosene and has NO lubricity.

It's 2009.

I saw a video of a guy using WD-40 to clean his gun,
he sprayed all the usual areas that would have gun shot residue
wiped it down and then used compressed air to blow it all out.
After that he lubed the gun.
So I guess he used it as a solvent.

I now use Marvel Mystery oil...works great!

Gummy heck!

When WD40 is done 'curing' it turns into a brown varnish.

I use it to remove crayon marks from the refrigerator.

White lithium will be a nightmare to clean, we use the stuff at wotk and in a few months time it will become hard and tough to clean up.

Has anyone used EEzox? I've just used it for the first time and have read some good stuff about it. It seems to rate at least as good as Breakfree for Lub and Cleaning but out performs Breakfree on Rust Protection.

Interested in opinions and thoughts.

When we shoot guns till they are red hot we spray them down with G96. The stuff works great. I have used WD40 to spray them down for the ride home. It will get a varnish on the gun that will need to be cleaned off.

WD 40 is a fish oil base.

This is not true one of the ingredients in it is very gummy and once all the solvent is evaporated it sticks around. I would tell you what that ingredient is but I would lose my job for giving up trade secrets.

It also works great to remove cosmoline from gun parts. I just buy it in the 1 gallon can. WD40 still has its uses. There are better cleaners out there now but I will still use it.

Another thing....Read the ingredients for WD40, it contains silica..i.e. SAND, i never put the stuff near my firearms. I would rather use CLP, or my homemade "Ed's Red" solution. Look it up online, works great for cleaning, and removing cosmoline and gunk. Soak the action overnight(minus wood/plastic parts. and blow it off and let it dry, voila, clean and rust free.

That isn't on the MSDS, do you have a reference for that?

Last time i read the can, it was listed in the ingredients.......But since i never buy the stuff anymore, they might have discontinued the use of silica, but i know it was used in it. Trapper Gun in Roseville also swears to not use WD40 for the same reason, he was where i originally heard about the silica.

The MSDS has a reference to "other" that makes up 10% of the total. It must be in there.

I use Birchwood Casey Synthetic Gun Oil, it comes with a Teflon additive and that stuff is the whip. A gun does not stiffen action wise in the winter and after sitting over a year the oil will come off on your fingertips

Formulation

WD-40's main ingredients, according to U.S. Material Safety Data Sheet (http://en.wikipedia.org/wiki/Material_Safety_Data_Sheet) information, are:
50%: Stoddard solvent (http://en.wikipedia.org/wiki/Stoddard_solvent) (i.e., mineral spirits (http://en.wikipedia.org/wiki/Mineral_spirits) -- primarily hexane (http://en.wikipedia.org/wiki/Hexane), somewhat similar to kerosene)
25%: Liquified petroleum gas (http://en.wikipedia.org/wiki/Liquified_petroleum_gas) (presumably as a propellant; carbon dioxide (http://en.wikipedia.org/wiki/Carbon_dioxide) is now used instead to reduce WD-40's considerable flammability)
15+%: Mineral oil (http://en.wikipedia.org/wiki/Mineral_oil) (light lubricating oil)
10-%: Inert ingredientsThe German version of the mandatory EU safety sheet lists the following safety relevant ingredients:
60-80%: Heavy Naphtha (http://en.wikipedia.org/wiki/Naphtha) (petroleum product), hydrogen (http://en.wikipedia.org/wiki/Hydrogen) treated
1-5%: Carbon dioxide (http://en.wikipedia.org/wiki/Carbon_dioxide)[source]

If it's late and I'm at a tent camp during deer season, I'll spray my rifle down with WD40 to get the water off after hunting in the rain or heavy snow. Call me lazy, but I'm there to hunt not tinker with my weapons. Spray it down, wipe it down, let it air out.

Break Free might do the same, I haven't tried it.

I don't use WD for lubrication or storage though. I've had guns develop rust after being stored with only a WD40 spray.
