The cleaning result with me:
Reinigunsflüssigkeit evaporates completely after the lapse, was unable to detect residues. - Ever positive.
Debris but were only distributed, not removed.
A swap with a lint-free cloth which receives particles would possibly make more sense. Soft cotton microfiber blend eg
Perhaps a page soft rubber lip to distribute cleaning fluid and loosen dirt, other side polishing cloth ...
Well, I do not know. Have two Swabs consumed and sensor still has a few particles.
