Trotec recommends to use following cleaning material:
Lens tissues Part number 69249
Lens cleaner Part number 69248
The lens has a durable multi-coating and won't be damaged by correct and careful
cleaning. You should inspect the mirrors and the lens according the maintenance
plan. If you discover a veil of haze or dirt, you must clean them.
Follow the instructions below for the cleaning of optical parts:

5.2.1 CLEANING THE LENS

1. Move the working table to a distance approx. 10 cm under the lens holder.
2. Move the working head into the center of the working surface and put a cloth
under the lens holder (so that the lens is not damaged if it accidentally drops).
3. Now you can remove the lens by turning the fixing ring and pulling the lens
assembly to the front.
4. Remove the coarse dust as good as possible by blowing air onto the lens
surface.
5. Check the surface and if necessary clean the lens with the lens cleaning
liquid and lens tissue.
