Dull grout haze, pitted into dark Porcelian tile

[donny2pins]

Hello there, what you should have done was seal the tiles before grouting : why you probably ask yourself ? well simple because the porcelain tile has tiny pores on the surface of the tile which will let in any stains or dirt.AND WHEN YOU SEALED IT .BANG THAT IS THE PROBLEM . YOU SEALED OVER THE GROUT MARKS THAT HAVE SUNKEN IN THE PORES.HOPE THIS HELPS.

What is the point of telling someone what they should have done? Close the stable door after the horse has bolted!!! They need help to solve the problem not tell them what they have done wrong

What has happened in this situation is the tile has been grouted and overwashed after grouting. This has caused all the polymers in the grout to rise to the surface that is why no acidic product is working because it cannot break down the polymers in the grout if you like trying to wash a dirty surface with a sheet of glass laid ion top of it. The correct solution is to clean all the tiles with Aqua Mix Sealing and Coating Remover. Allow the SC&R to dwell for about 15-30 minutes this will break down the polymers in the modified grout that was used. Then you can clean the cemetitious part of the haze off using a combination of a Grout haze cleaner by Aqua Mix or a mild form of Phosphoric Acid.

Thanks for all the info guys... I went down the Lithofin route and it seems to have removed the majority of the haze. There are still patches that require further attention but the general appearence of the tile is back to how should be!!! :hurray:
