Lava is a heavy-duty hand cleaner made by WD-40, first produced in 1893. WD-40 acquired the brand from Block Drug in 1999 who acquired it from Procter & Gamble in 1995http://www.fundinguniverse.com/company-histories/Block-Drug-Company-Inc-Company-History.html. It was originally developed by the Waltke Company of St. Louis in 1893http://www.wd40.com/Brands/lava_faqs.html. Unlike typical hand soaps, Lava contains ground pumice, which gave the soap its name. The soap and pumice combination is intended to scour tar, engine grease, paint, filth, and similar substances from the skin.
