Tools - wipe cups and wands clean with dry paper towel.
Molds - allow resin to dry, then pick off with fingernail - no need to wash Little Windows molds, that will only leave a residue.
On hard surfaces - wipe with dry paper towel, remove residue with cleaner like Simple Green or acetone.
On soft surfaces (fabric, carpet, hair, etc) - this is the hardest, you will want to wash with dish soap before it cures, until no longer sticky.
On skin - wipe with dry paper towel, then wash with dish soap until no longer sticky.
In eyes - wash with cool water for a minimum of 15 minutes, see a doctor if swollen.
