This is a serious question, really.

Irene has left us without power and, according to our electric supplier, it will be days before they can fix us up. I've been working all day clearing a downed tree and debris and I really REALLY need a shower. The pool water is cold, yes, but at this point I'd put up with just about anything just to wash my hair and body.

There are alternatives: I can bring in a bucket of water, heat it on the propane stove, wash my hair and do a sponge bath. I could drive to a beauty shop and have them wash my hair except I'm trying to conserve gasoline so I can use it in the generator if I run out. I could just check into a motel for the duration.

But if I wanted to use the pool as a big tub, what negative effects could I expect from soap and shampoo? The pool pump is NOT on, of course, and there is no filtration at present.
