[ARCHIVED THREAD] - Anyone else HATE WD-40? (Page 1 of 2)

WD-40 has got to be about the absolute worst penetrating oil ever produced. While in the hell is it so popular? I think anyone here that turns wrenches knows what I am talking about. PB Blaster or CRC oils are so much better. Damn worthless WD-40 |

WD40 stands water displacement formula 40, it is designed to leave little reside after drying. It will act as a light lubricant when applied, but it needs to be repeated or a real lubricant used after. I use it after things get wet to stop rust from starting, until things can be cleaned right. |
WD-40 is a light lubricant and a water displacer. Use it for what it was made for. Use a penetrating oil to penetrate.

WD-40 acts most like a spray-on kerosene, in my opinion. Good for degreasing, good for drying, bad for lasting. For penetrating lubrication of metal-metal, Silikroil > Aerokroil > PB Blaster in my experience. The Kroil products stink less than PB Blaster, certainly. For rust prevention of metallic surfaces, with some lubrication, Boeing's Boeshield T-9 which is available at boat stores. Slightly waxy looking residue, but lasts in incredibly harsh conditions, very safe, and works well for lubrication and for corrosion protection. Also "environmentally protects" electrical components, good for circuit boards in a boat environment as it is nonconductive once it dries. For penetrating librication of plastic:metal, plastic:plastic, fabric:whatever, McLube, a spray dry teflon, also available in boat stores. |

My insurance agent got his hands badly burned by WD-40 a few years ago in a shooting accident. Required skin grafts, many surgeries, etc. He was working on a Beretta 92 and had it at the range, shot it for a while then tore it down and was blasting it out with WD-40. Put a mag in it, pulled the trigger and the WD-40 left on the weapon and his hands immediately ignited and burned like napalm. Yes, it was a stupid mistake (stooopid mistake) but it cost him dearly and he paid for it with more than a pound of flesh.

I like it just fine. It is made here in San Diego, and is sold practically everywhere for little $$. While it works okay for general cleaning tasks, what I mainly keep it on hand for is to spray down my shooting irons after they have been rained on. It by no means should be the only product you use on firearms. It is so cheap and so readily available, that it is the product of choice for those tasks where you wouldn't ordinarily think were worth squirting expensive wonder oils with. |
I hope he had health insurance! |
