I recently moved into an apartment with porous natural stone tiles on the floor in the bathroom. After doing some re-grouting on the walls, I used a diluted solution of grout haze remover to clean some of the grout residue. I noticed that this cleaned the tiles so I cleaned the entire floor using this. Now the floor is much cleaner, and i want to keep it clean and also seal it so that cleaning is easier.
I did some research on line to see what the best way to clean and seal and maintain porous natural stone tile is, but cant find any good info or product recommendations.
