WD40 has been around since 1953 It got its name from the inverter Norm Larsen’s attempts to make water-displacing spray. The product we use was his 40th attempt to get it right!
I used it to spray on the damp car engine the other day and we use it to lubricate stuck screws, I have used it for stain removal (though rather smelly) and to clean the fiddly bits around taps. Here are 2000 other ideas you might be interested in.
How about this one? "Removes a Boa Constrictor stuck in engine compartment of cars"
The spray can is the same in France, except for the language. You can spot WD40 anywhere.
