Filmy coating on porcelain tile after cleaning
I have new ceramic tile floors in my sunroom. They have a smooth satiny finish to them. I had been cleaning them with soap and water and then I went with just plain hot water. Even using just plain water leaves a streaky apearance where I can see what looks like cloudy film and cloudy streaks when the light hits the floor just right. It's like each scrub pass leaves a hard water or just cloudy, dull marks. The floor does not shine anymore like it did when it was new. I used a Pledge product made for tile floors and it does leave it shiny new, but it seems like a waxy stuff that I wonder if it will build up after time like wax. Is there an art to cleaning porcelain tile floors?
