Question: “I just had a granite tile floor installed a couple of days ago. After several times cleaning the floor with water, I observed a few marks which I couldn’t remove. The marks looked like grout or mortar stain and a clear mark. What could I buy to remove stated marks and also to seal and shine the floor.”
Answer: To remove the grout residue follow these instructions: (Note*** this process is safe to use on granite- NOT on any calcite based stones such as marble, limestone, or travetine; vinegar will etch these types of stones, but IS safe to use on granite).
- Fold a paper towel over to 6/7 ply like this:
- Pour vinegar on the paper towels (enough to saturate) and let sit for 15/20 minutes
- Then using a soft brush and more vinegar, clean away the grout residue
- Rinse and dry the area
- Repeat process if needed
