We have the equipment to do any form of tile. Problem being with the back drops and tile walls results of cleaning will vary. This results from many things.
1. Our tile pre-spray needs to be brush applied instead of being able to dwell on the tile on the floor as gravity comes into play. This gives the alkaline cleaner less time to break down what it needs to.
2. We need to be very careful of surround painted walls and cabinets so sometimes the very upper edge may be tough to reach. In saying this however most of the time it is near impossible to see that part.
3. Many times bathroom tile will have 20 years worth of mildew and hair spray that can unfortunately be permanent depending on the situation and severity.
4. Fireplace mantles etc can be troublesome as well due to the soot. Soot is all impurities and is near impossible to remove in certain situations.
