The only service that I know of is http://microscopes.osu.edu/
I'm pretty sure that he only deals with OSU, but it might be worth a call. At the worst, they can say no.
If that is the case though, you can clean much of the scope on your own using some isopropanol that can be diluted 50:50 with water, do not use rubbing alcohol. Usually the insides of the optics in the microscope don't get very dirty from normal use. So first just clean the ocular, objectives, and condensor very well with some cotton gauze or lens paper soaked in isopropanol.
Another thing that can help the clarity of what you are viewing greatly is to focus and center the condensor. You can find decent instructions to do this under C here: http://www.cas.vanderbilt.edu/bsci111a/equipment/compound-microscope/light-microscopy.htm
If you find that you need to clean the inside of the microscope. The ocular lenses should remove easily and you can clean those easily and the objectives should screw out and you can clean those as well. if there are areas that you can't reach just use cotton swabs. Just do not take these lenses apart. At one point someone disassembled a few lens in the lab to clean them and it was a PITA to put it back together correctly without any dust getting trapped inside.
