Hi all, Hoping for some much need help. I purchase black polished porcelain tiles for my kitchen. After my tiler laid them (ignoring the fact they needed to be sealed before grouting) there was grey marks on them. I thought this was grout haze and bought lithofin cement remover which the tiler used on them, this made no difference and before i knew it the tiler had sealed them. Absolute disaster. I have sealed tiles, which still have stains. Is there any hope for my tiles?

Hi Annie and welcome..

A particle abrasive cleaner like Lithofin Abra clean or Aqua mix nano scrub should work at getting those clean.

The polishing process opens up pores in the tile surface and it is these pores that hold the dirt/grout etc.. and a good quality penetrating sealer helps seal those pores thus making cleaning them easier.

Thanks Dave, unfortunately the tiler has sealed the tiles already. Is it impoosible to get the sealant off, it was HG stain protector?

It can be removed enough to get them clean..

To remove the sealer then you need a sealer remover..

Aqua Mix Sealer & Coating Remover is a non-flammable, multi-purpose stripper formulated to stay wet longer which gives the product time to remove most sealers, epoxy grout haze, urethane coatings, synthetic finishes, adhesives, and paints. Also dissolves deep-set stains and removes heavy grease buildup.

Uses:

Natural stone (such as granite, limestone, marble, slate, and travertine), ceramic, porcelain, grout, quarry, saltillo, terra cotta, cement pavers, and masonry surfaces.

and then you need the abrasive cleaner to get the grout from the pores..
