I have gotten the question more than once, “Is it okay to clean my gun with WD40?”. It’s a fair question and I’ve known people who have been using WD40 for 20+ years to clean their guns. Are they wrong for doing this? Let’s take a deeper look into what WD40 is and if it’s a good idea to use it to clean your guns.
What’s In WD-40?
Most of you probably own a bottle but do you know what it’s made of? Probably not because it’s a secret formula! For over 60 years the multi-use product has kept its formula a secret from the public.
Another fun fact is that Duct Tape has also kept its formula a secret, which is why the original duct tape is the best.
WD stands for Water Displacement
What we do know is that WD40 is a special blend of lubricants. It’s a terrific solvent for removing rust and getting stickers off but will it do the job for cleaning your gun?
The Old Way to Clean Your Gun
Before writing this article I sat down with a good friend that’s been cleaning ALL of his guns with WD40 for over 30 years before switching to Break-Free. He’s never had any of his guns rust and any other problems for that matter. Some people seem to be biased on the idea of using WD-40 and tell me that they would never use it but let me tell you what my friend said.
Back 30 years ago there weren’t many gun cleaning solvents out there, so people were forced to improvise. There especially weren’t any aerosol gun cleaning sprays, so most people starting using WD40 when it came out.
When I used it back in the day I found my rifles to be very sluggish in their operation, especially in the winter. This issue magically resolved when I started using Break Free lubricant mainly because WD40 is not designed to clean your guns.
WD40 is a solvent that leaves very little oil on the surface. This means that more dust and dirt will be attracted to the surface and eventually you’ll have a nice layer of gunk on your gun. In cold weather this can be very bad and VERY big pain in the ass to clean off.
Conclusion
WD40 is an amazing solvent with about 1 million different uses (along with duct tape). After using is many times to clean my guns I’ve decided not to completely trust it due to the rapid buildup of gunk on my guns.
Thanks for the info bout WD-40 I don’t use it but have in the past done so but probably never will again thanks for the good read and important info
Years ago I used WD-40 to clean a pristine pre-64 Winchester because of was out of kerosene. Two days later I sat down to clean it properly and found the bluing had tiny pits all over the action and barrel. Never got them off the surface no matter what I tried.
Since that experience have never let WD-40 anywhere, I mean anywhere near a firearm since then.
DO NOT CLEAN FIREARMS WITH WD-40 !!
Funny how WD40 is recommended for cleaning guns on their own website with testimonials from people with tens of years of experience in the industry.
Yeah something I’d never recommend.
I have used wd40 on all my guns for over 45 years. Bolt action, lever action, auto, pump action, single shot. Long guns and handguns. I have 9 guns now. All but two for over 30 years. After i shoot a gun i clean and remove all oil. I wipe it down with wd40 on a clean rag and wipe off any excess with another. If i dont shoot a gun i wipe it down two times a year, inside and out. Before i shoot i reoil moving parts. After all these years i still have never ever seen any of the gunk, gum, waxy build up or anything others say. It never has rotted the stock, melted the barrel off, washed the blue off the metal. And none have ever burst into flames when shot. I have never had to replace any part from ware and never had any gun or part fail. And you will absolutely not find one speck of rust on any gun of mine. And that goes for my muzzleloader that i clean with soap and water. Wd40 on the same guns over and over again for over 45 years. All the bs about wd40 on guns is simply Not True. I can find nothing that even comes close to being as good as wd40. That comes from 45 years experience and not from hearsay.
I am like the other guy, I have been cleaning guns since I was 15,
Hops to clean and scrub the barrel,s with, a good follow up ofWD40 on patch’s that get deep in the groves. Then a light buffing with WD40 and a good rub down on the whole gun. Then a good clean old tee shirt to polish it with. I am 65 now, that’s 50 years. I have never had a auto jam, never issues with sticky residue on any of my guns. I am a hunter, and retired police officer and army vet. I would never not have WD 40 to clean my gun up with, it has never failed me. I still have the first gun I purchased at 20 and it looks used and carried, but the barrel you can’t find a spot in her, and not a spot of rust anywhere. No to mention being able to spay a good steam of rust, and dirt, and water residue from in side guns were you can’t get to with a oiled rag.
To each there own, I have to use mine twice, and it’s never failed me. So still being alive speaks good enough me!!
