Pitch pine block flooring, 1.25 inches thick. Most of the floor, particularly traffic areas, is covered with rugs with mats at entrances. It is swept daily and buffed regularly, waxed 2-3 times a year. Parts of the floor are now almost black with muck and grime. There is no appreciable wear and I don't really want to have to sand the whole floor which is about 50sq.m. The flooring when laid was sanded, sealed and waxed. Any suggestions for cleaning it please?
Nic.
