how do I get white grout with white tiles again?
We moved into a house of seven years and the white bathroom tile grout ceramic floor will not come clean. We have tried bleach, another brand, a steamboat and a lot of cleaning products that people said it work, but no help. We soaked and brushed. If I'm digging the grout and redo it, what is the easiest way? I heard a church key works. Yes, it is sanded grout. If I can clean and seal my wife could be happy with it.
A product called tri-sodium-phosphare will clean the place. coach
