I was convinced from somewhere or other the main thing was kerosene. But the WD people say it ain't so right there on their page. Pal o mine is saying it's fish oil. Say what?? What does WD-40 Multi-Use Product contain? While the ingredients in WD-40 Multi-Use Product are secret, we can tell you what it does NOT contain. WD-40 Multi-Use Product does not contain silicone, kerosene, water, graphite, or chlorofluorocarbons (CFCs). http://wd40.com/faqs/
From our friends at Wikipedia: WD-40's formula is a trade secret. The product is not patented, to avoid completely disclosing its ingredients.[3][6] WD-40's main ingredients, according to U.S. Material Safety Data Sheet information, are: 51% Stoddard solvent 25% liquefied petroleum gas (presumably as a propellant; carbon dioxide is now used instead to reduce WD-40's considerable flammability) 15+% mineral oil (light lubricating oil) 10-% inert ingredients The German version of the mandatory EU safety sheet lists the following safety-relevant ingredients: 60–80% heavy naphtha (petroleum product), hydrogen treated 1–5% carbon dioxide
Neither do I tbh, more: White spirit....Stoddard solvent,[4][5] is a petroleum-derived clear, transparent liquid which is a common organic solvent used in painting and decorating. Stoddard solvent is a specific mixture of hydrocarbons, typically > 65% C10 or higher hydrocarbons. Although not normally marketed as a fuel, white spirit can be used as an alternative to kerosene in portable stoves, since it is merely a light grade of kerosene. Maybe thinking along those lines? I'm not a chemist but to refer to is as light kerosene seems like a stretch, maybe different stage of petrol derived product.
I know it burns pretty good. In a Metalhead moment I used a torch on a bolt that I had soaked in WD-40. Yup, it burns.
Whatever is in it changed 7 or 8 years ago Used to use it as a starting fluid after dunking jet skis in the ocean and it worked damn well. Not any more.
Ha! first cold sweat I ever got was upon receiving a multi-guess chem test at college and not recognizing a damn thing. Still passed
Anyone know (without googling it) what WD-40 actually stands for/means? First one to answer correctly doesn't get a damn thing.
