I've tried all of the popular caravan cleaning products on offer, and without question the very best is Auto Glym Caravan and Motorhome cleaner. It's absolutely amazing stuff! Strange thing is, there aren't that many stockists.'Muck Off' and a long handles soft brush works for me. Plenty of water but don't jet under the roof vents or you will have a wet van.
