Cleaning stains from grey porcelain floor tiles

[sarah_louise_b]

My builder has just laid some black grey tiles in my bathroom, they are almost a slate effect
the make is unicom starker, porcelain tiles.

When the builder left I went to clean the floor, there is a large mark across the tiles near the door as if something has been spilt on them (?dirty water from the grouting), it looks a dirty, ive tried floor cleaner, tile cleaner, wipes, washing up liqiud and I cant make it look any better.

My builder has gone to Austraila for 6 weeks so I cant ask his advice, and my lovely new bathroom is not so lovely.

does anyone have any advice on what can be used to clean these tiles?

I hope these work:smilewinkgrin:
the first one is how most of the tiles look (i.e. no marks)
the other three are pics of the marks.

Lithofin Cement away..... but try it on one tile first before the whole floor...

Follow the directions on the bottle.... Also LTP grout stain remover is good.
