I am currently on a trip from FL to TX and before we left, I waxed the front of the motorhome really good and put Rain-X on the windshield. The bugs were bad one day and I cleaned them off that evening with a bucket of water and cloth.
No problems. I have used the wet dryer sheet in the past and like above poster stated, wash residue off.
Last weekend I cleaned the bugs from the front cap that had been on there for one week. With a water hose and cloth they wiped right off. This is the first cleaning since I treated with 303 protectant. After cleaning I reapplied the 303. The 303 is easy to apply and the difference in cleaning the bugs was amazing.
