Review on 303 Products Wash Seal Streak Free by Walter Martin

This product costs a little more than a standard RV cleaner. You don't need much in a 5 gallon bucket to create a sea of cleansing foam. When I applied it to my caravan with a soft brush I noticed that dirt and grime had risen from the surface. Quite surprising as I thought my caravan was fairly clean before trying this product. After rinsing off the soap as directed, I used a soft towel to dry the surfaces. After drying I noticed a really nice sheen and shimmer on the walls of the caravan. Got a really good finish with no wax/wax removal. Again, this is slightly more than other brands, but in this case you get what you pay for. Deep cleaning and great shine.
