A professional wash should differ through control, not through unsupported claims of perfection.

Remove contamination before contact

Loose dirt is rinsed away, wheels and lower panels use separate tools, and the technician adapts chemistry and pressure to the surface.

Inspect the result deliberately

Human inspection can identify residue around emblems, door shuts and other details that a fixed machine programme may miss. It also recognises defects that cleaning cannot remove.

Any contact method can create marks if grit remains in the media. AVP's staged process reduces that risk but does not issue a scratch-free guarantee or call itself the best wash in Switzerland.

Polishing and coating remain separate services chosen only after the clean finish can be assessed.
