What's your best non-lighting related tip?

[Sctiger]

I was today years old when I learned that cooking oils (i.e, vegetable, olive, etc.) work best for removing spray paint off of skin.  Worked like a charm. 
If you're like me during decorating season, your mind and body are in a thousand different places.  I always tell myself I don't need the latex gloves (or either my mind is somewhere else and I never think of it until it's too late!) 

Store that one away for future use.
