What is the best and safest cleaner to use on the vinyl sides of my new 2516g? I have some kind of tree sap (yellow) on the top part that is very stubborn to get off. So far I have only tried soapy water and a few cleaning supplies safe for vinyl......this stuff is tough to get off.
Mean Green HD. Rince it right away after you clean it. This was the product I was using to clean my tent trailer and I had no problems at all. I use it now to clean the black streaks on my hard wall trailer.
