How to clean the miners?

The use of air compressor gun alone is not sufficient for cleaning the miners from sand and dust and making the ready for immersion fluid. What is your procedure for proper miners cleaning and prep work for air to immersion transition?
Lessons learned: the fast-drying alcohol-based immersion fluid solvent with a small brush worked great! Not much volume is needed if you blow most of the sand off with the air gun. Looks like PSU silicone elastomer is notorious for accumulating dust. No option to blow it, just wash!
