If something sharpened or ground on a CBN or diamond wheel sticks to the wheel then it's the wrong material as they should be self cleaning
There are special cleaning sticks for CBN/diamond but they are not designed for routine cleaning but more to remove stuff that has (accidentally) galled onto the wheel because they will shorten the life of the wheel.

I usually just give the diamond and CBN wheels a blow down with the compressor.

I've ground glass a few times with the diamond wheel and usually spray water onto the wheel while I'm doing and that cleans it well enough but a couple of weeks ago I did a small piece without water and it left a fair bit glass dust embedded on the wheel. It also showed that my wheel needs truing up.

I tried blasting it off with the compressor nut it removed less than half of it.
I tried a few things to clean it up the most successful being a light brief application of fine steel wool

There's info floating around about how steel/iron should not be used with diamond but given that there are long life diamond impregnated thin kerf cutting blades sold for angle grinders then maybe thats no longer correct. I did a brief test of these wheels last year on the MW forum see Metal Cutting Disks
