I'm afraid of dry cleaning chemical types - but I have the luxury of living in a VERY dry area. We were talking about this in my "do your bathroom towels dry overnight" thread in my low carb forum
So if we steam clean our carpets here, they dry in under an hour. So we get super clean carpets, using just water and safe detergent (or heck just water alone sometimes) and then POOF they're dry.
The more I hear about these humid areas, the scarier it sounds. I can't imagine living in a moldy house!! I imagine there must be some benefits though
