Acidic Vinegar Grout Haze Remover
The vinegar and water solution works best with a mop or gentle scrubber that will clean up the surface of the tiles without scratching them. If you have any particularly stubborn grout areas, use the scrubber to remove them first, then wash away the grout with your mop.
Use warm water and wipe it over the surface of the tiles with a sponge. Then using some fine wire wool, rub gently over the grout which will begin to dissolve and rub off at the same time.
You can safely use vinegar to clean ceramic or porcelain tiles, whether they are glazed or unglazed. For other types, however, like terracotta, marble or grante, we recommend you look for ph neutral cleaner that will not harm the material.
The most common and effective homemade grout cleaner is a mixture of baking soda, hydrogen peroxide, and dish soap. Cream or tartar and lemon juice is the best all-natural solution for whitening. Avoid using highly-acidic solutions like vinegar because they can corrode grout.
Vinegar can indeed ruin grout.
Once lodged in these spaces, vinegar will corrode grout with the passage of time. The grout will eventually wear off. So you should take not to apply vinegar for cleaning purposes if you have unsealed grout in the area.
It should be easy to clean up tile haze with basic, gentle astringents, such as a drop of mild dish-washing soap in a gallon of warm water or a spray bottle filled with the standard straight vinegar. Vinegar won’t leave any residue behind, which some harsher detergents can be known to do on tile.
The first thing to try is to clean the tiles with a scouring pad and lukewarm water. If this does not work completely, use a mixture of 50% water and 50% vinegar. The acid dissolves the lime residues that make up a grout haze.
Grout haze occurs when residue from the grout installation dries on the surface of the grout and tiles. It looks like a white powder, seen in glossy patches, dull smears or streaks.
