Clean the lens and mirror after each job or at least once a day. Use cotton stick with aceton and lightly brush the surface of the mirror/lens.

Keep the rods oiled (no WD-40)

I (Duality) Quote:

Never use wd-40 as a lubricant. The primary ingredients in wd-40 are kerosene and mineral spirits, which can be corrosive and are otherwise not suitable for mechanical lubrication.

Also you don´t want a (wd-40) sprayed mirror ;).
