Thanks, Matty. This was a challenging project, but it worked out quite well.

To clean aluminum buildup on a carbide cutter, just drop the cutter in caustic soda (lye) and water solution and the aluminum will dissolve.

I thought of that, but a secondary reaction with the NaOH is with cobalt forming: Co(OH)2 which is a really nasty substance, especially in solution. It is exceptionally problematic to dispose of as it is toxic to aquatic life and has a long half life. For humans it is toxic in almost every way - Class 4. Here is a link to the SDS

Tip for removing aluminium from toolroom stones: sodium hydroxide in water. You don't need it to be super concentrated, a low enough concentration that it's still safe to get on your skin works fine. Just have a small container to soak the stones in overnight and all the aluminium gets dissolved. Works especially well in an ultrasonic.

Thanks for the tip and here's one back at ya: be exceptionally careful using sodium hydroxide to clean aluminum off of carbide end mills. The cobalt binder is also very slightly soluble by the sodium hydroxide and cobalt hydroxide is very toxic.
