SearchSoap
As might be expected, you can use soap to clean some items. You must either be holding or have the item to be cleaned in your inventory, and must also be holding the soap or have it in your inventory. Soap has limited uses, and will disappear when used up. It can be used to clean bloody, sweaty, and sewer-stained items. For tougher stains, you may have to resort to stronger means.
Syntax:
use soap <object>
Example:
use soap robe
