Bruce,Have you ever used S/Williams water based brush cleaner.It works wonders. Had a customer that didn't put the lid on a paint can on tight. I shook the can,I wore the paint the rest of the day. Hate to ruin a good pair of jeans,so cleaned them with the brush cleaner,rinsed them off good,put them in the washer. Turned out perfect.No fading,no paint. This might work on the brick,no garentees.
