At a recent show I picked up a handful of 3in cutoffs from the fine triangular ceramic stones that are evidently used in the Lansky and Spyderco sharpeners. They work very well but load up kind of quickly, and weren't flat on each face so I so took off some of the high spots on one with medium ceramic stone. I was surprised that the effective grit is evidently determined quite a bit by the surface roughness and only partially by the material itself, unlike traditional stones, as the now smoother surface doesn't remove material nearly as well as it use to.
Do people find that the ceramic stones wear out by getting smoother ?

 
As the pores of the stone fill up, they cut less and less. Use Ajax and a green pad to clean the stones and they will work like new!
 
I had to flatten out one of my synthetic stones ones, it didn't cut into the metal as easy after I smoothed it out. So I cleaned it out and just used it a bunch and it eventually finished the cleaning by itself. The first few times you use after re-doing the surface will probably be really slick and not very abrasive.
