If you've been Working on your Bike and you're out of Lava Soap

How're you going to get that bike grease off your hands?

After a pleasant evening of bike maintenance I found myself in this predicament, much too late to run to the store for soap.

On a vague hunch that it would be slightly abrasive, I tried washing my hands with toothpaste.

I can report that they are thoroughly degreased, and minty fresh!
