Showed this to my very green thumbed partner. She said sounds like mealy bugs, but the solution is the same as aphids.
Water/alcohol/drop of soap solution
70% isopropal alcohol - 1 part alcohol to 7 parts water, one drop of soap
90% isopropal alcohol - 1 part alcohol to 9 parts water, one drop of soap
Spray a cloth with the solution, then manually wipe down the plant. Spray the plant, but DO NOT put it under a light or in the sun until it is dry as the leaves will burn. Let it dry, then do manual removal of the bugs by wiping it down with the solution every day or every other day. It might take several weeks. Her exact words is that "It takes vigilance."
