Oh, and the less said about WD40 the better...
I have something worse. Although none on this list might suspect it, from
time to time I buy weird cheap items. Case in point, Soybean oil lubricant.
Reading the can made it sound like using the product would heal the ozone
layer, and it was 79 cents, so I bought a can. As oil it seems ok, but
STINK, it reeks for weeks.
