I forgot how H2O surface tension compares with for instance H2SO4. Anyhow I do know that WD stands for W ater D isplacement. Soooo the action of WD 40 (the fortieth formula) reduces the surface tension of moisture, causing it spread around (displace) (causes it to evaporate faster also I tink) Ric Tinker
