Everyone knows the problem by washing the vehicle in a car wash: The wheels are always covered by the cleaning agent with a film, which significantly worsened the view at the first turning on the wipers. Although Good washes distribute wipes but compared to the spray foam can only be described as these stopgap.
After applying the foam and short exposure I use to wipe normal kitchen paper towels. The wheel is super smooth, streak-free shine completely and you really have an optimal view. As even hoped even after turning on the wipers. Positive side effect: The wipers run absolutely smoothly and quietly. Remnants of wax on the disk from the last wash visit caused otherwise always unpleasant noises.
Overall, one can fully recommend this product anyway.
