got a Gatco sharpening set and it has worked real nice. Let a buddy of mine borrow it to sharpen some of his knives. Long story short, the stones no longer sharpen worth a darn.I noticed metal particles stuck in the stones. Tried to wash them but know luck.

Anybody got any sugestions?
 
Depending on how soft the metal is it may be difficult to remove. Maybe if you try some very coarse sandpaper it may remove some off of the stones. I don't think the sandpaper will damage the stones but I'm not sure. You could try it on a small section to see what happens. If he got aluminum on the stones then removal may be very difficult. Easiest solution is to have him buy you a new set of stones:).
 
I am unfamiliar with the Gatco system but have you tried Comet with a scrubbing pad? This works well on ceramic stones.
 
First the use of oil or water reduces metal pickup. When it does happen the recommended treatment is scouring powder.I don't know if a chemical treatment would work without damaging the stone. This might be peroxide for steel and sodium hydroxide for aluminum.

"Cameo Stainless and Aluminum Cleaner" will also work well.
It has sulfamic acid which dissolves and loosens metal particles.
Barkeepers Friend has oxalic acid, which does the same thing.
Get'em at your grocery, same place as they keep the Comet, Ajax, etc.
They're not expensive, and also work wonders to take metal streaks off your
ceramic rods.

Right ... another product with sulfamic acid is Scrub Free bathroom cleaner, which I've used for several years now to clean stones and ceramic rods. Just let 'em soak a good while, the acid should loosen even the heavy buildup you describe; some brushing may still be necessary, but this should work.
