I have just finished sealing my garage door up from drafts (as was fed up of it filling up with neighbours leaves) I have just replaced our house dehumidifier as old one was reluctant to start (handy for drying out a wet OES) I then repaired the old dehumidifier (motor cap had given up the ghost) it now resides in the garage with the mog where if I Park a wet mog in the no longer draughty self airing garage it will get shot of the excess moisture. The plus side is that the dehumidifier as part of its operation produces heat and is enough to take the chill out of the garage.
