WD-40

    ABOUT 7 OR 8 YEARS AGO I STOPPED USING WD-40 FOR GUN OIL AFTER BEING TOLD TIME AND TIME AGAIN THAT THE CHEMICAL WHICH LOOSENS RUSTED BOLTS IN THE WD-40 ALSO ATTACKS THE BLUING (WHICH IS A RUST)ON GUNS. THE REASON I'M WRITING IS BECAUSE I SEE SO MANY PEOPLE AT THE RANGE ETC. THAT ARE USING WD-40 FOR GUN LUBE. EVERYBODY THAT I HAVE ASKED THIS QUESTION CLAIMS THEY'VE BEEN USING IT FOR YEARS AND NO PROBLEMS WHAT SO EVER. ON INSPECTION OF THEIR GUN I HAVEN'T BEEN ABLE TO FIND ANY SIGNS OF WEAR THAT WERE UNEXPECTED, JUST ALL THE NORMAL PLACES, AND NO RUST. I WASN'T HAVING PROBLEMS WHEN I STOPPED USING IT, I JUST DIDN'T WANT TO CAUSE PROBLEMS.
    SO, WHAT DO YOU ALL THINK? HAVE ANY OF YOU EXPERIANCED PROBLEMS WITH WD-40? I'VE BEEN USING BREAK-FREE, AND FP-10 WITH NO COMPLAINTS ASIDE FROM THE PRICE, WHICH I GUESS IS THE REASON FOR THE QUESTION. I CAN BUY ALOT OF WD-40 FOR THE PRICE OF 1 CAN OF BREAK-FREE.

    I have been using WD on my guns for years and never had a problem. I don't know anyone who has had problem either.

    I've been using it for years too--no problems.

    The WD-40 cans used to suggest that it was good for use on firearms; I think the gallon jugs still carry that suggested usage.

    I don't believe I've seen it on the smaller cans recently--maybe it was determined to be more "politically correct" to not make that suggestion. (Or maybe the company was worried about some lawyer trying to sue them for "contributing to gun violence.")

    A few years ago I saw a thread on WD-40 and one poster who I believed worked for the company said that the name stood for Water Displacing -40 days. After 40 days it became water attracting.


    Remember, I saw this on the web, a grain of salt is in order.

    I have great luck with 3in1 oil. I have a piece of machinery at work with a machined iron work surface { boring bar }. When I first got it I used automotive motor oil to protect the surface from rust. Well guess what? Motor oil does not stop rust. I started using 3in1 oil and solved the problem.

    Nearly 20 years ago I sprayed some WD-40 on my remington, serial number 30511, which was a short, vent rib bolt action 308. Took it Deer hunting in Western Nebraska. It was cold out. Had a nice buck in my sight's: the WD-40 froze(not literally) my bolt. NO shot! HAVE NEVER USED IT SINCE...been using BREAK FREE.

    WD 40 Stands for Water Displacement- 40th attempt and was developed by a fellow named Norman Larsen back in the early 1950's. I've heard the same stuff about WD 40 being harsh on guns for many years and don't believe a word of it. It is a pretty docile substance and can be used on practically anything without causing any damage. People I know in various industries simply say it does a lot of things...none of them very well; It is a fair penatrating oil, a fair lubricant, a fair preservative, and a good water displacer. I think there are simply too many firearms specific top quality products available on the market and I see no real advantage to using WD 40 on guns...other than it is cheap.

    I"ve been using it for years with no ill effectds.I suspect the naysayers are just repeating what they "heard somewhere." I think first-hand experience counts for more than rumors and heresays.
    Iheard on a tv documentary that the "40" was the number of the most succesful recipe.
    And I like the price too!!

    I have never had any problems using. I do believe there is better things to use , but it is a good cheap lube to buy. lots of old timers around here used to use WD-40 to spray on themselves! Said it made their joints feel better! HAHA!

    WD-40 is a penatrating oil, if you use it on firearms KEEP AWAY FROM ANY CONTACT WITH PRIMERS. It will penatrate the primer pocket and cause misfires (as will any other simular product).
    Interior bolt care for cold and wet climates is another hole matter. YOU MUST STRIP AND DEGREASE THE BOLT AND FIRING PIN. I have used two type of lube on them after degreasing, graphite, or a LIGHT coat of syn oil. Both have never failed me even in some very bad weather.

    I never had any trouble with it but did see it once fail to stop rust. But only in extreme conditions. The gun was locked in a leakey unheated attic for 6 months and it rusted- a little- with WD 40. No trouble with RemOil or plenty of 10W30 in the same situation.

    I used to use it, but it didn't work too well with reblued guns. The penetraiting stuff in it removed some of the blueing in spots. This was only on reblued guns though. I use a regular oil(Rem Oil, Mobil 1, or Hoppes) now w/o a penetraiting catalist.

    wd40 is made to do one thing, displace water, it is not a 'lubricant', it does not disolve rust (before i got an oil bath i used it righ after reblueing to displace the rinse water), it does not protect against rust, it does make a fairly good cleaning solvent.

    Shut off your caps lock. WD is great stuff. There's just better stuff. Like LSA and Break-Free. It is great for temporary protection against water. As in in the field.
    WD is particularly good at cleaning and protecting electronic parts like the sensors on your vehicle.

    Yup, I agree with sunray, that sure it will work, but there's better stuff to use. I don't personally prefer WD-40, but for sure I don't recommend it, cause there is such a huge selection of products that are so much better for the intended purpose of firearms. Personally I recommend not just one or two lubricants or cleaners, but that a wide varity of them be kept. I find some particular lubes, solvent, and such work better than others for particular guns or parts. Its like some of my old mililtary rifles, I still put grease on them. But I use a q-tip and some mpro ultimate lube applied on most internal moving parts. Then I like CLP for use as a preservative, for VERY LIGHTLY lubing magazines and external parts. Car auto wax is also something thats handy to have for external, non-moving parts. And a wide range of solvents.

    I just find that for best performance and rust prevention and cleaning there really is no magical all in one that works best, theres always something that works better for specific tasks.

    From my experience, WD40 works for some things, as many pointed out. But growing up hunting in western Washington, it really sucked for rust protection. Any rain hunt was frustrating because it just would not hold up. I've switched to Tri-Flo and have been very satisfied. Wet sloppy hunts have not ended with rust showing with this stuff. Except for the price the stuff works better for moisture. I also keep a wide assortment of lubes for specific applications. Tri-Flo is not a one-can-lubes-and-protects-all material either.

    WD40 will turn to brownish sticky goop!
    How do I know, bought a new Springfield Trophy Match .45 in stainless, never fired it, cleaned real good with Hoppes, dried it, then sprayed with WD-40 & put it in the safe. A year latter I took the guns out for their annual cleaning. Noticed brown goo on the barrel & innards where I sprayed the WD-40.
    Now I use 3in1 oil no problems since.

    It's good if you spray a cloth, and wipe the finger prints off of your guns, after one of your buddies comes over and fingers everything in the safe. There are better protection products out there, as stated.

    I have used WD-40 for a long time, I use it a lot on firearms, however, I have found that a wet lubricant like WD-40 tends to gum up with dirt and what not after a period of time so you have to clean it off and reapply frequently. WD-40 also makes a fair degreaser to clean up guns and remove greasy/oily residue on weapons from stuff like cosmoline and what not. I use it in the field, after I'm done shooting my guns out in the forest or desert or wherever I happen to be I wipe them down and clean them up right there on the spot with WD-40 and a few other things time provided of course. However, I have found that dry lubricants like graphite work better for longer periods of time than stuff like WD-40 and if my gun has wood furnature I rub in a bit of lindseed oil and wipe it down.

    I agree with the above poster that there are more specific products now that are better than WD-40 at one specific thing but for speed and ease of use in it's application to a firearm it will serve just fine but it does tend to gum up with dirt and spent powder residue. Just make sure you wipe it off and reapply it every now and then while the gun is in storage and clean off and reapply after each time at the range.

    I get good results with "Tri-Flow". Naturally, BreakFree is great stuff, too, but pricey. For cleaning, either brakeshoe cleaner, when I need a quick "hose down", or at home on the bench, good 'ol Hoppes. Bear in mind, viscosity of a lubricant is a prime spec. WD-40 is very thin. 3-in-1 is much thicker, and doesn't flow as much where you don't want it to. You sure don't want the sear of a auto pistol to get gooped up with slippery stuff, or have oil dribble down on your trigger finger while you are trying to shoot. As for motor oil, remember these are made for the dirty, hot interior of a crankcase, not a firearm. They have detergents and other additives with unknown properties on firearms.

    Has anybody used wd-40 as a starter fluid instead of ether? I've used it on chainsaws and lawn mowers with good results.It maybe easier on rings than ether.[8D]

  • rldowns3
    LOL, you can use a lot of things for starter fluid as long as it's fumes are as combustable as gasoline or ether lol.

    Jim Rau has the right of it quote:WD-40 is a penatrating oil, if you use it on firearms KEEP AWAY FROM ANY CONTACT WITH PRIMERS. It will penatrate the primer pocket and cause misfires (as will any other simular product).

    WD-40 is fine for most uses but DO NOT use it (or any penetrating oil) on a carry or duty weapon.
