Since it's starting to smell already, you may have waited too long? Wouldn't your Home Owners Insurance pay for whatever needs to be done?...ours did. Our washing machine had completely overflowed, soaking partially into the wall-to-wall carpeting of the living room, and two bedrooms! This special company (can't think of their title) came to our house to cut-up and discard the soaked part of the carpeting, then for about 3 or 4 days there were about 4 of these huge loud blowers running 24 hours, aimed at the floor, bottom of walls, and woodwork, to completely get everything BONE DRY again, before ripping up/discarding the remaining carpeting. Then the brand new wall-to-wall carpeting was installed. It was a major project, but it only cost us the deductable portion of our Home Owners Insurance policy.
