Parę ciekawszych cytatów:
".Application of new lubricants.
The most important thing to remember is absolute cleanliness of the parts on your microscope before applying fresh lubricants. There is no point in applying new expensive grease or oil if there is the slightest remains of the old lubricants - you will just get a horrible mess where the two lubricants start to interact. The Russian tank grease applied to their older scopes tends to be acidic and attacks the brass sliding surfaces like the main focus or condenser movements and should definitely be removed. I have found after complete disassembly [controls, screws, nylon or metal drives etc] of the focusing mechanisms that a disposable lint free paper towel dipped in white spirit removes most of the old Russian grease [be prepared to use several applications] and then use isopropyl alcohol to remove any traces of white spirit. I usually leave all the cleaned parts a few hours to let any cleaning material evaporate in difficult to access parts like screw holes. If the brass surfaces of the microscope seem blackened or pitted due to acidic lubricants I have found after thoroughly removing the grease deposits that watered down kitchen cream cleaners, Brasso or Duraglit can do a good job of bringing back the finish, indeed I have used kitchen cleaner on a Biolam stand recently that had not been used for some years and by the time I had finished, all the brass surfaces were gleaming. Again it is essential to leave no remains of the cleaner, for some of the larger components I have rinsed the whole part under the tap and let it dry it off

General cleaning of paintwork.
The paint on the Biolam and Bimam ranges varies from a light mottled green to grey and is usually applied quite thick, no more than a cloth dampened with a mild solution of washing up liquid should be needed but particularly stubborn stains can be removed with any one of the cream kitchen cleaners like Ajax, Jif or Cif as they call it now applied with a small cloth to the offending area. After a good clean these microscopes can look like new even after 30 years of storage or use.
.
The difference when using a cleaned and freshly lubed microscope like this one compared to a typical LOMO off the shelf say from eBay after it has been neglected a while using LOMOs original horrific tank greases is nothing short of a revelation and is part of the reason why the Russian microscopes have such a poor reputation in some countries.
.
Conclusion: Are these specialist and quite expensive lubricants worthwhile? Definitely, especially if you like renovating old microscopes, the difference in the feel of the controls especially the coarse focus having just the right damping and silky smooth action makes using any of the older microscopes a pleasure especially compared to the make do feel of household lubricants. Highly recommended."
