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 diamond sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance is only needed every year or two.
In 1-2 years you may need to flatten stone, 20 mins with Ferric chloride (FeCl):
- 10 mins setting in 25% mixture (25 gr FeCl per 75 gr of water),
- 10 mins polish movements (carefully draw "8") on glass plate.
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 dimensions selection window (click also any grain size to select it). I sell it if you buy a stone.

CUBIC BORON NITRIDE, CBN, BORAZON
HONING, SHARPENING STONES
CBN (cubic boron nitride) is a generic name, there are also other names of this material, depending on manufacturer: borazon, elbor, cubonite, etc. 
CBN (cubic boron nitride) is the second-hardest material after diamond,  and has the best price-performance ratio for processing steels, comparing to other materials, including diamond, silicon carbide or aluminum oxide.  
Due to it's high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones.

Use and cleaning of CBN sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance is only needed every year or two.
In 1-2 years you may need to flatten stone, 20 mins with Ferric chloride (FeCl):
- 10 mins setting in 25% mixture (25 gr FeCl per 75 gr of water),
- 10 mins polish movements (carefully draw "8") on glass plate.
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 dimensions selection window (click also any grain size to select it). I sell it if you buy a stone.
