What crystals do you mean?

Hello, thank you for your attention, To the set of crystals located in the laser unit and to the glass that is between the laser unit and the advance unit

QSS33 has the worst optical unit concerning dust removal.
The gap between the lenses is almost impossible to have cleaned and I guess the culprit of the issue is right there.
Do not use alcohol during cleaning, by the way.Try to use a canned air, I hope it will help to remove the piece of dust from in-between space.

Thank you very much for your attention, is it advisable to remove the crystals for cleaning? ......

I do not recommend disaseembling of the optical unit. Please use canned air first.
