ONCE OFF is specially made for cleaning ceramic, porcelain and quarry tiles that are difficult to clean. Many of these types of tile have tiny holes or pores in the surface. Dirt collects in these holes and gives the tiles a “grey” appearance. Where ordinary detergents are ineffective on such tiles, ONCE OFF is excellent. Its powerful cleaning and penetrating action draws the soil out of these tiles. ONCE OFF may also be used to clean concrete, bluestone, sandstone, terra cotta and clay or concrete pavers. It is ideal for use on floors in shopping centres, toilets, shower rooms, kitchens and carparks.
