For those of you who want to try Borax... I spend several days trying to find a local supply of 20 Mule Team Borax (Kroger, WalMart, Sams, Home Depot, Lowes, Janitoral Supply, plus many more). I was about to give up when I finally found it at KMart. Cost was about $3.95 per box.

PS: Am I the only one who remembers Ronald Reagan's 20 Mule Team
commercials?
