Miracle Sealants Miracle Heavy Duty Tile & Stone Cleaner, Grout Haze Remover, Non-Acidic, 32oz

I bought this to clean hard water buildup on my tile grout. I have hard water and it creates a haze on my dark grout. It doesn’t take much to get the job done so it will last a long time. It does have a strong scent so wear a mask for safety. And make sure there’s ventilation.

I purchased this to address the grout haze on the tiles of my newly purchased home. It hasn't worked thus far.

Worked wonders

I bought this to clean my shower tile and it worked great on the tile. My bathroom is only 5' x 7', I had the window fully open and the exhaust fan on. I wore thick kitchen gloves, a mask, and my prescription glasses. Now, 5 hours after, my eyes and the skin on my neck are still burning (I must have unknowingly splattered). I have taken 2 showers and washed my eyes several times and although it has lessened I won't be using this again.

This doesn't work, at least for grout. After realizing this was probably not working, I did an experiment, cleaned two areas one with this product and another one with just water. They both performed the same, but this product has a terrible smell and leaves a residue. Just bad.
