What should you use to wash porcelain tile?

Daily cleanings should include sweeping and damp cloth wiping. A variety of daily cleaners are available; my own favorite is Dupont Stonetech Revitalizer, but there are many others. Miracle Sealants makes a good one, too. To really get the tile clean you will want to use a mildly acidic cleaner but these should not be used frequently as over time they will damage the grout, the base mortar, and perhaps even the tile. If, after installation, your tile looks icky and dirty and has white residue, you will need a grout haze remover. Follow the directions carefully to minimize damage to the grout. Significant buildup of wax, sealant, etc., can be removed with Citristrip, available at most large hardware stores. After using haze remover, Citristrip, or other harsh products, you will want to reseal the tile. I use Miracle Sealant "511 Impregnator."
