I think today wasa particularly humid day, drying just wasn't happening!
Did a heavy cotton suite and then all the carpets (huge house) starting with the carpet in the same room as the suite. Even with 2 blowers put straight on and belting away at the suite it wasn't properly dry 4 hours later and the carpets weren't properly dry before protector went on.
All windows locked. I lost count of the number of times I had the same conversation with the customer who said "Oh we'll put the heating on later". I said "uhmm well we really need to get some air circulating..." "Well the heating comes on at 4..."
AARRGGHH
