* Pump flush and brush if required. Hot as you can stand laundry or dish soapy water followed by just as hot clean.
WD-40 is great for things electrical - had an outdoor outlet start tripping the ground fault device, and found that condensation had gotten everything sopping wet. I flushed it out with WD-40, drilled some vent and drain holes, and it's been fine since. It also worked great on an underground cable TV connection that had gotten wet.
It does a dandy job of getting rid of moisture, which of course helps prevent corrosion. I wouldn't get it on wood, except maybe to clean off greasy grunge on a on-shot basis. I use a pump sprayer now, rather than buying the aerosol cans of the stuff, because it's cheaper, easier to control, and I don't like breathing stuff like that. Although it's helped a lot of folks with arthritis - maybe you can cure emphysema by breathing it :no:
I think of WD40 about the same as coca-cola and apple pie!
