Ranger 111, please let us know how the Aqua Mix Deep Clean worked.
I did have a bottle of the Aqua Mix Sealer that I used for the one section that I have cleaned. I have one edge of a tile that did not come clean with the Norwex descaler product that I used for the rest of the kitchen. Bleach didn't work either. I didn't seal that one spot because I want to try other things that were mentioned like vinegar, baking soda, etc. Looks a bit odd right in the middle of my kitchen. Not sure what I will do if it doesn't come clean. What a job! I am having a family party at my house tonight. Kitchen floor looks quite interesting. . .

Only a third of the kitchen floor is clean and sealed with that one dark line in the middle of the clean section!
