Green Grouting

[user123]

Next time I get a strange rash on the skin I'll know where to come Mosaic Girl, That was educational

Spent ten years of my professional life as an osteopathic, herbalist & homeopathic practitoner, after other patient related professions, and now I just want to play with mosaics and tiles, much less draining than people in pain....big change....and you can see a permanent result by the end of the day! The odd rash? Easy peasy... Greening grout? Perfect research opportunity - my forte....:yes:

Cathy, if you want to try and see if hydrogen peroxide works, get the 6% solution from the chemist, it's very cheap, 100ml usually in a dark brown bottle. Put some gloves on, pour a little into the lid or an eggcup and apply with a well soaked cotton wool bud. If it works on your grout you should see it almost immediately, don't leave on longer than ten minutes, rinse it off thoroughly, pour the used solution down the sink (perfectly safe) followed by water, rinse the lid or the eggcup well, and keep the rest in your medicine cabinet as a throat gargle (instructions usually on the bottle) and to remove fruit juice stains etc. Don't dip the cotton wool bud directly into the bottle, as you won't be able to use any of it afterwards.

If the peroxide doesn't work I'd have it redone keeping the copper reaction in mind.

And let us know how you got on!

Thanks for all your info Mosaic Girl! I shall try the hydrogen peroxide and let you know how I get on. I would have thought the pipes are well flushed through by now; it's been nearly two months since the tiling was done.
Whitebeam, thanks for your info, what sort of time scale do you think the article is talking about for the fading?
I just wish that we had got a proper tiler in now instead of letting the builder do it! You get what you pay for...

I'd have it redone, Cathy, but filling the buckets from another tap in the house that hopefully hasn't new pipes leading to it yet, or maybe even ask the neighbours?
Treating only the surface of the grout wouldn't really be enough if the whole mix is involved. Saying that I'm aware that only part of the grout is affected, which may mean that at some point your pipes were flushed through enough, wouldn't risk that though.
I think I'd also make sure that only non metallic tools + buckets are involved, just to be on the safe side.

I'm sure once pipes have been purged it'll be fine drawing water from them. I think builder has used this water for washing off rather than for mixing grout otherwise the whole grouted area would have been contaminated.It seems he's started washing off, seen the discolouration and then got clean water to wash off the rest hoping that the green area would lighten back to white!imo:grouphug:
