How can I clean dark brown grout stains from a light beige porcelain tiles?

[Soyabean]

Hi there, I have just had beige porcelain tiles fitted to a bathroom and left a section of around 15cm for some brown mosaics tiles to go.

They grouted the mosaic tiles today using Mapie 144 (chocolate brown) which I got and it appears to have stained the tiles a little.

He says that he has tried to clean it with water over and over again but it doesn’t work.

I was thinking of trying white spirit. Is that a no no?

Any idea's welcome.

Many thanks,
Sel

What finish are the porcelain tiles..?

Well they are smooth and an employee of the supplier told me they were sealed and that I didn't need to worry about using a sealer on them. Not sure how else to describe it. Could you give me any pointers?

maybe you should ask the tiler who grouted them to come back and clean them.

Are they polished..?

No they are not polished. They are are matt finish.

I just tried warm soapy water with a sponge which has an abrasive side to it and that didn't do a thing.

I also tried rubbing unused white grout on them as someone said to me that is a good way to remove stains from porcelain tiles but to be honest I think you would be there for ever and it didn't exactly remove it all either. It helped in few places though.

Right I better start Googling the grout residue remover products. Has anyone had success using these. Not sure how effective it's going to be in my situation but of course I will try anything as long as it doesntt cause more damage than good!

soya if the tiler stained them then surely he/she should be paying for products to revive themor even have a knowlege of suitable cleaning products .
try ltp , hg or lithofin websites to find what you need

Thanks for the advise brinkley. My builders tiler did the tiling (great job) and another of his general builders did the grouting. While the main grouting was fine as it was limestone in colour, we wanted a dark brown around the mozaic tiles which are also dark brown. I coudn't get that until yesterday and it was done today.

I will be speaking with my builder in the morning but wanted to know if there was much chance of getting it off. To be honest it looks to me like the grout which is really dark in colour has stained the tiles but I hope there is a way to improve it. The grout used is dark chocolate like in colour. Oh boy, why can't anything be easy?!
