I have never cleaned my 180 CBN wheel. I have been careful and have used it only for HSS and V10. I saw a "cleaning stick" on Amazon made by Norton, 1X1X6 Type 54 Dressing Stick 38A150-Ivbe. It says for cleaning CBN wheels and is made from aluminum oxide. I'm guessing it is used the same as the rubber sticks used for sandpaper. Has anyone used this? What is the preferred method to clean CBN wheels?
