A.S.
I never even thought about saying anything about what you made your edit about... : ) Goes to show that people only focus on what they want to most of the time... *giggles*
Anywho, I think the only thing that worked for me was a mix of Borax and water into a paste... Scrub it in, put a towel over it and tape the towel down for a few days. Pull it off after a few days and vacuum it up.
It worked for my ex-husband that wet the bed (at 30yrs old)! Lol!
