For those of you, like me, who hate swirl marks and marring of your coaches finish.
Has anyone here tried Image wash products? They have a two step touches wash system which works remarkably well. Step one is a highly alkaline soap solution, step two is a citrus wash. Spray one over the other and then power wash off using an extension wand in order to get close to the surface. Amazing! It will remove 90% of the grime and road dirt off. Especially if your coach has a ceramic coating. Dirt just rinses off.

It's a great maintenance wash or even a prewash for those of you like me who like a sparkling clean coach and still want to brush wash. Since it removes most of the grime, there will be less abrasion from pushing it around with your wash mitt. About the only thing it doesn't remove is water trails caused by the gutter run off.
I was able to complete a full wash and rinse in less than two hours!
Great stuff, FYI!
