I have a large commercial account that has about 100 people a day walking on its porcelain tiles each time we clean it I am never happy with the results
Grout starts off black and is suppose to be light grey it cleans up well but still shows dark in some areas
We deep cleaned with tsunami and rinse then went over problem areas with a ph 2 acid
Still some areas dry dark and some light
What’s your thoughts
