I love WD-40. Just bought a fresh two pack from Amazon.
If you have ever removed an adhesive label, and adhesive was left behind...WD-40. I use it to clean off chain lube splatter on my motorcycle and bicycles. On my bikes, after water washing, I hit the various components with WD, to remove moisture and lightly lubricate. I use it on my golf club pull cart, to lube the pivots, and clean grime off the frame tubing. It brightens up dull old paint on things like this also. I handed my kid a can and rag, and he went to town on all the plastic and painted parts of his MT07, and the bike looked like new afterwards.
No fallacy that it's a great lubrication, but it's better than nothing, and has quieted down many things like door hinges, electrical switches, etc. Bash if you want, I like the stuff.
