January 22, 20224 yr Hi all, can anyone help identify what this staining is to the grout? a quick Google has brought up it possibly being pink mould but wanted to get some other opinions as well? For info, the grouting was completed in the first week of Jan, and the bathroom hasn't had any heat on until today. the bathroom is not in use and won't be for another 3-4 weeks. thanks
January 22, 20224 yr Not necessarily mould. Has the shower been used at all? Is the staining close to the shower or everywhere?

Shower along with the whole bathroom has not been used, and most likely won't be for another 3-4 weeks at least. This particular area in the picture is behind where the bathtub will be. There's another area which is on an opposite wall and one more to the side of the toilet. The toilet is the only thing that's plumbed in and operational, and has been for the last 2 weeks. House is unoccupied so toilet only used when we're here doing work.
January 22, 20224 yr It could just be dust from the building works. Plaster/bricks / clay tiles are that colour, and it shows on grout. There shouldn't be any mould on new and dry work. Clean off and see what happens.
January 22, 20224 yr Completely normal for a bathroom with no heat in - or a warmish bathroom where the cleaner (me) consistently misses a bit . Dilute bleach and a scrub once a week will do fine.
January 22, 20224 yr Author @saveasteading Tbh there's been no such dusty works since the finishing of the grout. It's just been installing the fittings, toilet. Outside of the bathroom there's been skirting and loft insulation but we have a dust guard thing down over the bathroom entrance. Been trying all sorts to clean it off. It hasn't so far budged. Was thinking of getting some grout or mould cleaner from screwfix on my way back over tomorrow and seeing what effect that that but thought I'd seek advice here first. @ToughButterCup I'll have a go tomorrow with the diluted bleach and scrubbing and see how it gets on. Bathroom is slowly getting some temp in it so hopefully by the morning it'll be better. Thanks for the heads up!
January 22, 20224 yr If the tiles are real marble then bleach is the right thing as it will kill any live stuff but not attack the tiles. ie don't use brick/grout cleaner (acid). Then let us know the outcome.
January 22, 20224 yr Author @saveasteading Tiles are porcelain. Grout is epoxy grout. ok to use diluted bleach on it? Edited January 22, 20224 yr by vala
January 22, 20224 yr Thinks...Porcelain is chalk, which is lime, which is alkaline.. so yes. Absolutely. but still wipe off after doing it.
