Got these pits with rapid polish lodged in them with no way to get them out, any advice?

Best way is an ultrasonic cleaner. the next best way is tooth brush with soapy water then put in a freezer. Sometimes the wet will grow ice crystals that pull/push out the polish similar to how hoarfrost lifts dirt.

Afraid freezing them will fracture/ruin the slag. They don't fair well in the cold. Guess I'll have to grab an ultrasonic cleaner.

A water jet cloth cleaner is the best, they are probably cheaper than an ultrasonic too.

Gently, some of the Leland Blue is very soft.
