Abstract
The hard floor surface in common food preparation sites can have complex soils that are difficult to remove. Such floor can have two surface qualities. A first surface contains an array of quarry tile. The second surface contains a grid of grout lines surrounding the tile completing the surface. Each surface provides particular soil removal problems. We have found a unique product sequence, used in a method for cleaning hard surface or hard quarry tile floors, that is surprisingly effective in removing soil from both the floor tile surface and grout lines. The resulting clean floor surface maintains a clean quarry tile surface, a white new appearing grout line having no substantial build-up of soil residue. The floors obtain a clean, slip-free surface that is clean, sanitized, and has improved safety from slip and fall accidents.
