How to clean porcelan tiles?
I saw your post about problems cleaning your marble floor too. I'll bet the main problem is your water, especially for the porcelain tiles. You should not have any problems with glazed tiles, whether ceramic or porcelain.
You probably do not wipe the tiles after showers, do you? Well OK, most people probably don't, but all those minerals do build up. You need to get an acidic tile and grout cleaner and just follow directions. DO NOT use this type of cleaner on your marble though.
You can apply a penetrating sealer on the grout and also some on the tiles to fill the microscopic pores. Be sure to wipe off any excess before it dries on the tiles. Aside from sealer, some people have used Gel-Gloss or even Rain-X to protect the tiles from minerals? I know the sealer route works and is safe to do.
