Check out "1001 Uses For White Distilled Vinegar" at Vinegar Tips.
Three of my favorite tips:
"To clean and disinfect baby toys add a good-sized splash of white distilled vinegar to soapy water."
"Kill germs all around the bathroom with a spray of full-strength white distilled vinegar. Wipe clean with a damp cloth."
"Never use white distilled vinegar on marble. The acid can damage the surface."
