Cleaned a reception of a large sweet maker a couple of months ago, using one step, agitated with rotowash, then bonneted. Also extracted a bad bit with one step at foot of stairs, for future reference. Customer impressed, and booked more work. Had a call today to do the reception again. MD had gone on holiday, and reception filthy again. I`m not complaining and I think it my be sugar dragged in from production floor when employees use it as a short cut. Does anyone use protector on floor tiles, or think of any better way to clean?
