1. Apply degreasing agent to the floor area, 1:3, agent to water.  Apply with a 4" paint brush, two tile courses at a time.  Allow 5 to 10 minutes for the chemical to activate.  Spatter with water should it dry out before this time has elapsed.  Scrub the floor with a deck scrubbing brush vigorously.  Mop up suds with towels or a sponge mop.  The tiles should show patchy areas, exposing the original surface of the tiles.

1. Repeat the procedure for more stubborn spots, which didn’t come away the first time.

2. Continue on to the next two courses of tiles.

3. The following day, apply a solution of Turpentine/Linseed Oil 5:1 mix.  Apply with a 4" paint brush.  It should soak into the tiles after 5 minutes.  Any wet areas should be mopped up with towels, so as the whole floor is matt and not with glazed patches.  

The following day apply Beeswax polish, leaving it to dry for 10 minutes before shining with a shoe-shine brush.
