Grout stains on porcelain tiles.
Use a wet dry vacuum to pick up the dirt.
If you still see stains on the tiles or in the grout you can use an acidic cleaning solution to further clean the tiles and grout.
Grab your spray bottle.
Also many times the tile installer has left a grout haze on the porous porcelain tiles.
Grout is a porous cement based product that can absorb water and therefore stains if.
Catch the haze before it hardens.
While porcelain tiles are nonabsorbent and fairly stain resistant the grout that surrounds the tiles is not.
If you apply a sealer for porcelain tiles to the tile surface it will tend to help in not getting dirty as fast and will make it easier to clean.
Buffing the haze.
Use a 1 1 ratio.
Many times the grout will be extremely difficult to clean on the porcelain tiles.
Then rinse with clean water and use the vacuum to pick that up.
This product can be used in diluted or concentrated form to assist removal of stubborn residue.
Firstly the problem arises due to tiny microscopic holes in the surface of the porcelain these are like air bubbles under the surface which when the tile is polished which means grinding away the surface until smooth have their tops taken off thus we get small irregular holes not always big enough to see with the naked eye but certainly big enough to become filled with grout.
After applying grout wait 10 minutes.
Use a brush on an extended handle and scrub the tile and grout using a neural based cleaner.
