It's my understanding that the
Klasse AIO, as the name implies, is both a polish/cleaner and a glaze (where the Klasse
SG is just the sealant/glaze).
AIO should wipe off with a MF towel and then be followed with the SG.
If there was a dusting 'problem' you might mist with water, but shouldn't need to. I wouldn't use QD because there could be soap or wax like materials in the water.
The key to both I think (as previously mentioned) is to use a very small 'whisper thin' amount across the surface, making wipe off much easier.
