Orangey grouting, Scotland

Grouchy

Wondering if anyone has a suggestion.
Orangey/pinky grouting in shower in the wet areas but only visible when wet/damp. When dry it is nice and white.


I've tried all the OS type options, bleach, bleach and baking soda, cif, vinegar, spray bleach left for a few hours. Nothing seems to work.


I'm in Edinburgh and with very soft water (lovely!) so wondering if this makes a difference. I'm assuming it is either bacterial or some kind of iron residue from the minerals in the water?



Someone told me there was a special product you can buy but couldn't remember the name.


Any suggestions? Ta.

We have soft water, and this happens in our shower.

I had assumed it was from the copper piping, don't know if that's the case.

We've tried various remedies, the only thing that really works is re-grouting, I think. Though you can get a whitening pen for grouting from DIY stores, that works for a while.

Sorry, I'm not much help

Astonish make a mould spray that works great on tiles,you spray it on and just leave it,you don't need to rinse it off.It brightens the grout,it works on any marks not just mould, it smells like bleach,I have a cleaning business so I use it a lot .
Homebargains sell it for £1

The pinky stuff is mould, I get it too and was baffled for ages as my perception of mould is black.

I spray HG mould stuff when needed. I suspect it's just expensive bleach but won't throw it out.

I use a mould and mildew spray. Spray along grout lines, leave to soak for 10 minutes or so, clean off with an old toothbrush or a non-scratch bathroom sponge. Mine go from orangey to white doing this.

Hope that helps.

As far as I am aware it's a mould that shows up in soft water areas. I find Cilit Bang or HG sprays are good at lifting it. For grout I tip some of the bottle contents into small tub, soak a cotton bud and "painting" the grout lines with it with works better than just spraying.

Thanks all for views.


The Astonish one is much cheaper than the other sprays but doesn't appear to list active ingredients clearly, so wondering if this is a weaker, poorer acting product. Does anyone know? Not trying to be a cheapskate on this, just Astonish I saw is the one most stocked. Happy to anything to get rid of the discolouration though!



GERS - yes I was also baffled by the colour and always associate mould with black/grey.


Thanks

Wilko used to sell a mould spray for 75p which was excellent on pink mould. Sadly they stopped selling it. It smelt of peroxide.

I've got the Astonish Mould and Mildew remover and it works just fine, had mine a couple of years so they might have changed the formula.

It's algae. I second the Astonish mould and mildew, I use it all the time.
