There are some Pros and cons in soft touch washes. Here are the cons
Soft cloth can exacerbate preexisting conditions (loose molding, loose mirrors, nonfunctioning power antennas, etc.). If something on the vehicle was partially broken before, chances are it may be more damaged after the wash.
If the surface of a vehicle is not properly emulsified before reaching cloth (power sprayed or foam conditioner applied at first arch), the cloth an use the soils against the car and cause scratches.
