How to clean my roof

I use an Extendable RV soft bristled brush that hooks up to a hose.  Of course I use a ladder to get the top.  This past weekend I wash and waxed Nuesto Pod. (I use a good quality carnuba wax. It's about 4 hrs from start to finish) So I think I am good on the wax for at least 6 mo.  We try to keep the Pod covered especially in the summer with the sun & heat here in S. TX.  

I USE A FOAM MOP I GOT AT THE DOLLAR STORE IT HAS A LONG HANDLE WITH FOAM AND A WRINGER,I GET ON A LADDER AND START AT TOP OF AC AND WORK DOWN.I USE A PRODUCT CALLED TRAILER GLITTER RV WASH BY CAMCO. I GET GOOD SERVICE FROM THIS PRODUCT.I BY THIS FROM A DEALER HERE IN FLA I THINK ITS ABOUT 15.00 A GAL.GOOD LUCK AND BE SAFE,rex stuart fla
