Black mould in sink?? :(

MercilessKiller

Hi lovely MSE'ers

I moved into a brand new flat (newbuild by Barratt London) about 18 months ago and it's been an absolute dream. Great furnishings/fittings and a couple of teething issues were instantly resolved by the builders. Really happy with my experience.

BUT, I've noticed that in one of my bathroom sinks (other one is fine), there is a blackness appearing around the sinkhole bit and I can't seem to get it off (not that I'm an expert on any particular methods).

My worry is:
1) It could be dangerous if mould
2) It could be expensive to fix/replace

I'd love any thoughts on this? Thanks!!!

See attached for images. You'll see that oddly, the sinkhole bit is flat so even when fully open, water does stay/collect on the silver bit and around the edges oddly. I imagine that's what caused it...

Thank you!!!

That is such a small amount that i'm not sure if this is a joke?

(maybe not... in which case use bleach left to soak on kitchen roll around the stain overnight. Also works for black mould around bath sealant.)

your taking the micky?

"My worry is:

its a bit of dirt, clean it out, use a cocktail stick if you can't get the edge of a cloth in there.

Not joking! but feel a bit dumb now

There was like a little rubber sealent that's not there anymore (I feel like that's what's gone black). It won't come off though.... Even with an old tootbrush and bleach! I left bleach in overnight and then scrubbed with a toothbrush and it didn't even touch it

You're right re the small amount but at the same time, it's obvious when looking at the sink and if it is mould I don't know what's safe or not

Next try - go to wilkos or £ shop and get yourself one of those magic erasers. The flash ones are good, and get everything off.

Wet, wring, scrub, repeat. Give it a few goes but it might work wonders!
If that won't get it off then it might be a mark on the sink that won't come off.

Well, it's definitely discolouration of the plasticy bit - so the mark that's furthers out for example is rigid (it's a bit of sealent or something) but that colour really won't come off. I'm guessing the colour of the plasticy/rubbery bit has turned black.. that's the issue.

The magic erasers do get everything off though - worth a go!!

Thanks Will give it a try!!!

HG (Hagesan) mould killer is excellent on mould

I'd guess it's either caused by limescale so treat with vinegar or possibly sealant residue.

Perhaps a bit alarmist thinking it's dangerous but I didn't think you warranted being humiliated. 18 months and a pristine sink seems to be permanently scuffed, I'd be upset too.

Any

I do think it's tiny and most definitely not dangerous.

I love this. We have large shower corner with mosaic, that is not ventilated 100% (need better fan in next bathroom!) and you get a lot of black marks forming over time.. I spray this on tiles, shower it off after 5 mins (without scrubbing) and it's gone.
