I’ve recently started using these stones. I’m using kerosene as a cutting fluid for them which seems to float a lot of debris out of them but what’s the best way to clean them during use when they do start to load up?
Thanks
 
the only time I ever need to clean a stone is if I'm using light pressure large surface area application such as deburring dings from a machine tool table or grinding large flats. ninety-nine percent of the time, the EDM Stone breaks down into a slurry and that slurry does the cutting. The stone itself never needs to be cleaned, it is friable and breaks down in use. if you are running into a problem in normal use, you might not be using the right stone?

I use falcon tool diamond thinner not kerosene. I don't know if that makes a difference or not. I know you can use WD-40 in a pinch, but it's not great and it does get gummy as it dries. Kerosene may be similar.

Thanks Nathan,
I’m using Gesswein die maker stones 220, 400, 600 grits I use them just on the flats instead of sandpaper just because I can keep bevels crisp with them.
Kerosene seems to float a lot of debris out but I notice they cut much better at the edge of the stones where they are cleaner, I’ll try some diamond thinner as you suggest.
Thanks

Might need a softer stone too, if it's a large area and modest pressure. I think that could clog and glaze a stone.
 
Try Bar Keeper's Friend cleanser. Most grocery stores have it.
Comet cleanser will also work.
 
I just dip the stone in a citrus degreaser and that seems to make a good slurry and the stone material wear away and cuts
