Toothpasties

I'm trying to figure out a balance between learning and upkeep. In doing so I see that I've been slacking on the cleaning end. So I cleaned like a madman yesterday.

In doing so, I remembered the magic cleaning solution my grandma uses:
Toothpaste.

Tables, tiles, chairs, ink sinks, rust (or whatever) on porcelain, and 90% of other back room materials can be scrubbed incredibly clean with toothpaste. Start off with nonabrasive toothpaste; I just rub it in with a paper towel. If the mark won't lift, jump over to the more abrasive toothpaste with baking soda.
