Recommendations on selection of sharpening stones
How to maintain sharpening stones
Preparation of sharpening stones
Stones with grits finer 3 microns either require preparation (dressing), or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well.
This is common issue for all manufacturers: abrasive grains are covered with bond, so you need to "release" them.
"Stone preparation" is not available because of war.

Use and cleaning of CBN sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.
Maintenance (in 1-2 year), flattening/revitalization:
- resin bond stones - with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl.
There are other methods (with SiC powders..), but method with FeCl, on glass plate is the cheapest and simplest.
You may buy 100 gr. of FeCl in grain selection window. I sell it if you buy a stone.
