what is a WD40?

Answer 1

WD40 is a lubricant/cleaning spray popular in engineering circles (and elsewhere) in England. You spray and it loosens overtightened nuts, cleans rust and so on.

Answer 2

It is a closely guarded formula for a spray lubricant made by the WD40 Company. It lubricates many things like locks, fittings, etc. and is a general all purpose product.

Answer 3

Its a lubricant to use with hardware and stuff that sticks. Its a 'housewife's' friend. And as my pal EverWolf professes, its one of only 2 things one needs in life, WD40 and duct tape. If it moves, use duct tape, if it doesn't move, use WD40.

Answer 4

WD40 is a lubricant - they have their own website if you want to find out more about this product!@ The website is: www.wd40.com/

Answer 5

its actually a water based degreaser- hence the WD--it is NOT a lubricant. tho if your grease is congealed it will loosen it and thats why some think of it as a lubricant. I use a teflon based spray as a lubricant or oil/grease, - any/eiotehr of these are much better...

Answer 6

It's a type of penetrative oil (which contains cleaner, lubricant and anti-corrosive solution) that combines all three of those functions in a spray form, which makes it easy to apply. It is useful for many different things like stopping doors from squeeking and loosening rusted nuts and screws.

Answer 7

WD-40 is the trademark of a widely used penetrating oil (cleaner, lubricant and anti-corrosive solution) developed in 1953 by Norm Larsen, then working for the Rocket Chemical Company, to eliminate water and prevent corrosion on electrical circuitry. It is widely considered a "miracle liquid" by householders around the world because of its vast number of uses, which number in the thousands.

A common myth is that "WD" stands for "war department", seemingly because of the product's military history, but in fact WD-40 stands for "Water Displacement, 40th attempt". WD-40's name comes straight out of Norm Larsen's lab book. Larsen was attempting to concoct a formula to prevent corrosion — a task that is done by displacing water. His persistence paid off when he perfected the formula on his 40th try. [1]

Its first industrial use was by Convair, which used WD-40 to protect the outer skin of the Atlas missile from rust and corrosion. The product first became commercially available on store shelves in San Diego in 1958.

Main ingredients, from the material safety sheet are: 50% Stoddard solvent (mineral spirits), 25% Liquified petroleum gas (presumably as a propellant), 15+% Mineral Oil (light lubricating oil), and 10-% Inert ingredients

In Australia, WD-40 is in direct competition with Selleys RP7. At one time there was for sale in Mexico a similar product called "WB-50," whose name apparently had no meaning other than to market it as an alternative to WD-40. In fact, most countries have a number of similar clone products from local manufacturers. GT85 is equally common in the United Kingdom, and has (to most people) a more pleasant odor than WD-40.

Answer 8

A lubricant -- If it doesn't move and it should, use WD40.

Answer 9

wd-40 is a brand of penetrating oil its solvent based but not good as a lubricant seeing as it dries up best use id freeing rusted parts and loosening bolts nuts but after you should use a lubricant

Answer 10

A well-known penetrating lubricant. Check out their site:
