Hey Trevadea, that is a really cool instructable. Incidentally, the cheapest and easiest way to clean your hands of almost anything (including, in my case, motor grease, oils, grime, workshop debris etc) is a small glob of dishwashing liquid and a handful of sugar. Rub hands together and after a minute, run hands in water under a tap (faucet) The sugar acts as a bio-degradable abrasive which shifts almost anything. No more need for any expensive garage hand-washing products. I love the simplicity of it.
