One of the most asked questions I get asked when I clean carpets for people is “When can I put the stuff back?”. What they are asking is usually “when can I expect the carpets to be dry?” The answer is “well that depends on what you do”. The air flow through the house and the temperature make all of the difference. Having the room temperature around 70 and having a couple of ceiling fans on will sometimes cut the dry time in half. However making the house colder and turning off the air circulation can more than double the dry time. A while back I had a customre who had us clean for them in a new home they were about to move into. It was cold outside, we cleaned in the evening and as soon as we were done they shut up the house turned the heater down to 40. They were very surprised the next day when they came over in the morning and the carpets were still slightly damp. As soon as they turned the heat up the carpets dried quick but they were concerned. In the summer months I have seen carpet dry in as quick as 45 minutes when there is adequate airflow and warmer temperatures.
