Here is some general information about cleaners:
"Soapless detergents" are also commonly found on supermarket shelves. They include such cleaners as Spic & Span, 409, and Greased Lightning.
Scouring powders which are readily available include Comet, Bon Ami, and Ajax. Nylon scouring pads may also be used (such as Scotch Brite), but steel wool pads or any other course are not recommended. ( Do not use scouring pads or any abrasives on polished stone)
Do not use any cleaning agents that contain an acid, such as vinegar.
Do not combine ammonia and household bleaches.
Do not use harsh cleaning agents (such as steel wool pads) which can scratch or damage the surface of your tile.
Do wear eye protection and protective clothing as required by the manufacturer.
Do test scouring pads in a small area first.
Do use a silicone or solvent based sealer on grout joints if continuous staining is a problem.
Do read and follow label directions for all cleaners.
Grout Care and Maintenance:
Grout may present a special cleaning problem because it is susceptible to many staining agents. For maximum protection you should do a deep clean and apply a good sealer to grout joints once a year.
In addition to keeping the grout clean, be sure to keep grout joints in good repair. Scrape out loose, cracked or powdery joints and refill with a good grout. Corners should always be caulked, not grouted.
One common grouting trouble spot is the joint between the tub and and the wall in your bathroom. As the house or tub settles, the grout may crack and crumble. It's relatively simple to remedy. Remove the old grout with a sharp pointed tool, watching out that you don't scratch tile or tub. Then dry the joint thoroughly and fill with a flexible caulking compound, such as a Latex silicone caulk. You should be able to match the caulk to your grout color at any tile store. If you have trouble please feel free to call me.
