I suggest to go to the Welcome section of the
Forum and introduce yourself first. Members
will be more willing to help someone that they
know a little about.
Don't forget add your Global Location in your
Profile so that Members can help you better.

99% Isopropyl alcohol with medical grade cotton swabs if you want to do it properly. I find regular old Q-tip brand cottons swabs work just fine for cheaper optics though.

Fairly detailed information on cleaning procedures/tools/solvents available here: https://www.repairfaq.org/sam/laseratr.htm#atrcln

First contact is good, but pricey if you're only ever going to use it a couple of times.

Use compressed dry nitrogen. Smooth-on sells it. It's called Xtend It. I assume the modules are seal.
You seem to have responded twice...

If the optics don't have anything stuck to them I would try a dry cotton swab first before using a fluid such as alcohol or lens cleaning solution. I use medical swabs on wooded sticks. They seem to work well.

One more thing. Maybe my lasers are out of aligment. When i turn them on ,while top cover of housing is opened, I see that most of beam just passes trough reflective mirrors.. I can post picture tomorrow so you can see if its right or not :D

Which reflective mirrors? I'm assuming this is RGB or RGY?

If so, there's going to be several mirrors. There will likely be 2-3(RGB) or 1-2(RGY) for combining the colours, so they should pass or reflect depending on the colour.

There will be an additional two on the scanners themselves, one for the X axis and one for Y.

A picture would be good! :)

A picture would help! :)

Yes, they are dichroic mirrors for combining lasers at different wavelengths. They should pass/reflect based on wavelength (colour).

I don't see a problem with the lenses, but if you are planning on cleaning the dichros, I don't know if alcohol would be safe on those.
