It's penetrating ability has been known to cause primers to fail or misfire. Either could be very dangerous. I have used WD 40 for many years on my hunting arms and am careful that any excess is wiped off and that the ammunition does not come in contact with the solvents in WD 40.

by gthurman - 11/26/04 6:18 AM In reply to: Re: WD40?????????? by WillyWhen WD-40 appeared in the early '70s, we thought it would be great for drive motor lubrication of computer tape drives. It was for a few days. Then the shafts seized. What remained after the volitale agents were evaporated was approximately 70 weight oil according to our lab. I always judge if what I want to spray, over a long term, can tolerate 70 weight oil.

In conjunction with my earlier post and this link should explain things far better than I from memory.
Hope this helps -----Willy

Where would I be without my Duct Tape, Hay Baling Wire,
by John Robie - 9/25/04 3:25 PM In reply to: WD40...history link by WillyLiquid Wrench, and WD-40.
A absolute honest true story:
Years ago when I had a 1940's era auto, the right front tire rod (ball socket connected to steering of right front wheel) fell off dragging on the ground. Came to a halt as just couldn't steer properly with one wheel. Well, fished around in the trunk and found a coathanger. Mind you now, this was before Duct Tape was invented. Used the coathanger to wrap around and hold the socket in long enough to drive 20 miles home then next day 20 miles back into town to the auto dealer to get replaced. The mechanic could hardly believe I could have made it with that coathanger. Even today, I always have a coathanger and Duct Tape in my trunk.

Re: WD40...history link WarningAbout Plastics.
by cmpenchina - 11/26/04 1:04 PM In reply to: WD40...history link by WillyWorks great as water displacer and as long term lube.
They used to (maybe still do) sell it much cheaper (per unit cost) in gallons. They also sell a refillable hand operated sprayer (at high cost) so I used leftover sprayers from household cleaners. They worked well for only about a day or two. The company tech support explained that WD40 causes plastic parts to swell, and kills the spraying action. they had to make a very special sprayer to work with WD40.
So be careful when using around plastics. The effect may not be good.(They don't seem to supply this warning).
Aww....come on now tell us
by John Robie - 9/25/04 3:13 PM In reply to: Re: WD40?????????? by reipphwhat brand name is approved by NASA and better than WD-40. You won't be spamming or advertising unless you are employed by the company and then that will be debatable used in the context of this discussion.
I have heard and could it be a product from the X-IR corporation that produces also a gun lub/cleaner, or the VCI Vapor corrosion inhibitor with their numerour spray types labeled NOX-RUST, or perhaps Bullfrog (Bullrog) Rust Blocker approved by the Navy and used by the Military and NASA?
Please tell us.
Re: Aww....come on now tell us
by reipph - 9/27/04 10:13 AM In reply to: Aww....come on now tell us by John RobieCan't remember the brand, just saw it in TV shopping, I will tell you when I see it again, could be X-1R's, didn't try it though, as I said, they claim to be better than any lubricating brand in the market, but a claim is a claim and an advertisement is an advertisement. I am still using WD40 though and they had been used by NASA too. There are many new lubricant brands being advertised now, even X-1R's is a new product (correct me if i am wrong) and history will judge for their effectiveness. LOL.

by BABatson - 10/1/04 9:02 PM In reply to: Re: Aww....come on now tell us by reipphHere in Central Oregon, 'TRI-FLOW -- Superior Lubricant' is the favourite. It is made by Sherwin-Williams Company, Cleveland, Ohio 44115. WD-40 tends to wear-off, it seems to me, and I really like TRI-FLOW. However, it ought not to be applied to the body or inhaled overmuch; I do not know if WD-40, which has been popular at least 35 years, is more body-friendly, and I never heard of using it for arthritis -- it does contain liquid silicon lubricant.

Well, I'll be a little crass and add to my post.
In article <...> B.Hamilton@irl.cri.nz (Bruce Hamilton) writes:
>The WD stands for Water Displacing. I haven't analysed it,( not commonly sold here ) but somebody (Professor Toraki? )squirted some down a GC/MS and confirmed the solvent was boiling around 150-200C and only contained a minor % of aromatics, which means it is either a narrow boiling range kerosine fraction, or a special narrow boiling range solvent like low aromatics white spirits.
It is listed as Stoddard Solvent - which is actually a low aromatics White Spirit. It would have a boiling range between 150C - 200C and an aromatics content below 20%. According to various sources, the typical liquid product contains:-
70% low aromatic white spirits ( stoddard solvent )
~20% lubricant base grade ( solvent de-waxed, paraffinic type )
10% of corrosion inhibitor ( some formulations use 2 inhibitors, normally they would only be present at low concentrations, so it's possible that the inhibitor could be something crude like an oil that produces a hard film with synthetic additives )
5% of wetting agent ( probably quite low concentration, other the formulation would emulsify some water which could affect theprotective film's durability and performance )
<5% of fragrance.
The aerosol versions adds 25% of LPG as propellant to the above( probably with less of the wetting agent to minimise foam )
My earlier suggestions aren't too different from the above.

by Scargill - 11/26/04 1:08 AM In reply to: Re: WD40 composition by techuserHere in UK I use WD40 at work, & we need to recieve a product Data sheet with an order.
It stated it was composed of Oil & White spirit.
There is certainly more, as you state, Bruce, as you can smell the perfume, and the wetting agent is probably soap. (these would not need to be stated.)
You could make, very simply, a good substitute at home, out of things in the workshop. When I worked as a Radio & T/V repair man, we used to make it in this fashion if we ran out of switch cleaner. (Remember this?)In fact to reduce the risk of corrosion a lot if items, (Soft greases oils etc) were mixed with parrafin substances, as when they were painted on the surface, the solvent dried out, leaving the greasy coating to exclude the air, so preserving it. That said, Its very handy in aerosol form. I bought a second hand gas cooker of a lady that had altered the kitchen so it didnt fit. She picked up a can to spray & clean the grease of it before I took it! Handy stuff

by laurieprior - 9/8/08 4:14 AM In reply to: Re: WD40 composition by ScargillWD 40 doesn't contain what you'd think of as oil.
Also in the UK I did some background study of WD 40 before using it in damp sticky piano mechanisms.
I had a letter from the manufacturers of the patented product when they were owned by Cadulac Chemicals in the 1970s They informed me that the product contained
Animal Waxes (that is Tallow)
Petroleum based waxes (rather like Vaseline)
All borne up in a 3 to 1 concentration of White Spirit.
This is like a turpentine substitute.
The turps does most of the Surfactant work displacing water and the waxes do the lubrication.
It was safe to use in Piano actions, on wood, cloth and brass pivot pins and didn't dissolve any of the old fashioned Scotch Glue, or Animal Glue.
The company said I should be careful to make sure I didn't use it on any Cold-moulded plastics and there aren't any of those used even in modern pianos.
The lubricant was used to free up sticky components that the wooden parts had swollen with moist air or damp conditions. It was very effective and had no long term side effects.
So I just thought I'd put in my two penny worth to let you know it doesn't contain oil. Or at least it didn't when the inventors started making it.
I think the US Navy invented it and they had 40 attempts at the right formula hence Water Displacer 40
Hope that doesn't all sound smug but I thought the record needed straightening.

Re: WD40??????????
by Zia - 10/1/04 1:23 AM In reply to: Re: WD40?????????? by WillyIt stands for Water Displacement - 40 th attempt.
That's the name straight out of the lab book used by the chemist who developed WD-40 back in 1953. The chemist, Norm Larsen, was attempting to concoct a formula to prevent corrosion -- a task which is done by displacing water. Norm's persistence paid off when he perfected the formula on his 40th try.
