I use a dehumidifier to prevent my classic cars rusting in the garage.

Regarding recent letter about garaging wet cars. Of course they deteriorate very quickly as there is no air circulation to evaporate the water - ideal conditions to encourage formation of rust. For many years I have run a small domestic de-humidifier continuously in my garage, which holds five cars. Most are antique, so much more prone to rust than modern rust proofed tinware. I do keep a modern in there also, and regularly drive it in when wet. It is always completely dry by the following morning, and has never had a speck of rust on it. MOT testers have always commented on this. Also bright unpainted metal on the antiques remains bright and does not rust over many years. The dehumidifier extracts about two gallons of water each week. The cost is little over that of running a 100 watt conventional light bulb continuously. In my book it's money very well spent.

Good thinking. But that's a big garage, with much better air circulation than the average garage car tomb.
