Lava Soap And Magic Erasers

So...allow me share a little learned-from-experience wisdom here: Since, without a doubt, you will get disgustingly dirty in this class, I would suggest you purchase two fairly inexpensive products that will help you beyond belief in this class:

Lava Soap...

...which comes in a pump bottle like this...

...or in bars like this.

And Mr. Clean Magic Erasers.

Lava Soap has been around forever, and has pumice mixed in with the cleansing soap. The pumice is an exfoliant which removes the top layer of dead skin cells. That's where the charcoal is. It'll also get up under your fingernails nicely if you use it well.

Magic Erasers are a bit newer, having only been developed in the past decade, but DAMN do they work! They are the perfect thing to take dirty charcoal fingerprints off of walls, desks, chairs, 3D design work, etc. without damaging the surface of whatever you are cleaning.

Neither of these will make for a huge investment on your part. A few bucks spent now and you avoid a lot of problems down the road.
