I use the standard DSLR lens cleaning kit.

Dust brush, bulb blower, cleaning solution and cloth.

Always apply the liquid to your cloth, never spray in on to your objectives

Just standard glass clean solution works too.

But I generally avoid cleaning.

A few specs of dust mean nothing in the overall scheme of things

So many times have I see damaged optics by over zealous cleaners

It depends on the nature of the dirt.  Water and 90% isopropyl alcohol take care of most, but I have used WD-40 (on a Q-tip) to remove really greasy spots (WD-40 is then removed with 90% isopropyl alcohol).

 

To apply solvents, 100% cotton Q-tips, and Kimwipes work well, but plain facial tissues are OK too, according to Televue.

 

Blow dust off with a bulb before any cleaning and never use canned "air" (the "air" is actually a chemical propellent that can leave an oily stain). Dab rather than wipe to avoid dragging abrasive dirt across the lens surface.

 

These are the methods I use after a lot of reading and experimentation on old beaters that I didn't care about.

I have been using Dust-Off compressed gas for decades. No harm, no damage to lenses.

Used at the proper distance, with common sense, it works very well.

Read the instructions. graduate.sml.gif

 

During the winter months, in a semi arid climate, when static electricity is at work,

Dust-Off is really very helpful in removing clingy dust particles which refuse to budge.

i use a bulb blower then i use 90% alcohol 10% distilled water in a small spray bottle preferably and optical lens cleaner solution if really dirty.  i prefer to soak the outer lenses and then use a q tip to gently remove dust and dirt out the lens followed by zeiss disposable alcohol soaked cloth.  this soaking approach sometimes causes me condensation issues but i have found it floats dust and dirt better than and other approach.
