We pulled our toy hauler from Oregon to St Louis to Omaha to Colorado Springs to Salt Lake to Oregon in June this year. I failed to get to the washing job for ~ a month. I found the front of the unit was covered in bugs that were dry and stuck. I used the dryer sheets and was pretty surprised how well it worked. After getting the front clean I waxed it with some good paste wax and using the electric buffer it went pretty fast. I only washed the sides and back with an auto washing pad. I see the difference in the waxed area daily and it cleans much easier. I am very surprised how well the fabric pads work. I really wonder if it softened the bugs or the texture of the pad was conducive to removing the bugs. Either way they really worked well. I was able to do all this in about three hours which I thought was pretty good.
