Diamond Bur Cleaning Stone
Also know as a wet stick, this stone will quickly renew the grit on most diamond. Moisten the cleaner stone and grind the clogged diamond bur into it. (Always keep the stone wet or you will damage your diamond grit. Forcing the bur to hard and getting it to hot will cause damage).
