OK, way back when I used to buy a can of lye at the supermarket, stir it into a couple of gallons of water in a galvanized tub, add a cup of cornstarch dissolved in hot mwater, and come up with a real nasty finish remover which would be active for several hours. Brush it on with a fibre brush, keep it moist, usual rubbing and scrubbing in corners and such, and blast out with the hose. Of course outdoors, and eye, gloves protection manditory. Repeat, probably. Vinegar rinse that evening, take a look next day. Repeat if necessary.
