Re: Urgent - Washing machine overflowed in basement
Another option would be to get some carpet fans from a rental yard. These are squirrel cage type fans that duct out along the floor, made to be slipped under the edge of the carpet to blow air underneath and dry everything out. The problem with this is that all that moisture is going to activate the dirt odor that is already in the carpet and pad, so as MLB suggests, pulling the carpet might be the better thing to do, at least in the area directly affected. I would then replace the carpet with a solid surface such as tile of vinyl.
This emergency is why it is imperative to make sure that the sink is always devoid of anything that can block the drain, including a wash cloth or rag hung over the edge that might get pulled in if it gets wet with the waste water in the sink.
