Bathroom mould

nnb

Having issues within bathroom and need help! I don't use heating in there and had no issues in summer, I can only assume heat from surrounding apartments is helping make mine a breeding ground????

* black mould within the rubbery part of grouting around bath. This has been there since before I got here. I've kept it under control but it's started to spread now. I've tried bleaching to kill some of it and have taken a baking soda paste and toothbrush to it. It's still growing. How do I fully remove it?!

* Slimy black is starting to build around chrome fittings - most of these I can clean, but it's getting the thing that you twist to lower/raise the plug I can't get behind or seem to remove to clean and if I have a bath, my bathwater gets near that which I don't want to be soaking in!

* toilet has started leaking black from under the rim where water comes from. I clean it once a week and this is a brand new issue. It's a built in cistern and I am not allowed to put a Bloo block in there. The bowl's literally leaking black the next flush after I've scrubbed it within an inch of its life.

I love black but not in my bathroom! Pretty mortified my bathroom is looking like this. Any help appreciated!!!

Probably humidity rather than heat.

The grouting/sealant needs completely removing, the areas cleaned with a bleach solution, dried and then new grout/sealant applied, preferably anti-mould stuff.

The slimy stuff - a weekly clean and dry around fittings should keep it at bay.

Toilet - check the cistern to see what's happening in there.

Bathrooms are the dampest room in the house or property. Steam from showers and baths cause major moisture.

They need major ventilation to combat this. I have used antimold grout and sealers but even that went black aftee a while. But now I leave the window slightly open on first lock even during winter and its helped a lot.

As per the post, I do clean weekly. However I cannot get behind the twisty thing for the plug, and I cannot see anything in the cistern.

Being a flat, I only have a ceiling vent, not a window, in there. I always leave my bathroom door propped open to allow air to flow through 24/7. The issue is only recent.

This is exactly my experience. I have an extractor which seems to have little effect. You can control it but from my experience. it will always be there to some extent
Screwfix No Nonsense, or Hagesan mould cleaner are good, but strong smelling mould cleaners

Sorry didnt read it was a flat. Could the ceiling vent be blocked in some way? Or air flow to it restricted? Concidering its only a recent problem.
Sadly in my experience leaving the door for air never worked. Ventilation seems to be needed from elsewhere.

Does the twist control for the bath waste have a hole on the underside? If so, it needs a screwdriver, or allen key to undo the screw in the hole, it can then be taken off for cleaning.

If not, then try closing the waste, put your foot on the plug in the bath to hold it closed, and turn the twist control anti-clockwise. Go gentle just in case it is not that style of mechanism.

The final option is that it just pulls off. If you get two table knives under opposites sides and lever it off by applying equal pressure on both sides of the knob, it should come off.

If the toilet cistern is clean, then the leaking black from under the rim is probably just mold due to the condensation. My favorite mold remover if HG Mold Spray. It is strong stuff.

If you use the toilet, then dry under the rim, then spray under the rim with HG Mold spray, and avoid using the toilet for as long as possible. The spray should get rid of any mold that is lurking there. Be careful though - don't accidentally spray it in your eyes! Goggles (not glasses) would be a good idea.

PEOPLE! AMAZING NEWS!!!!
I was in Poundland earlier buying a few staple cleaning bits and noticed Cillit Bang 'Black Mould Remover' which I've not seen before. Only £2 so thought I'd give it a whirl. Just sprayed it on the bad bits, left 15 mins and washed away and scrubbed gently with a brush (forgot to buy sponges, doh) and it removed LOADS! What it didn't remove, it has turned pale brown. This includes on the silicon sealant!!!!!!!

Pure black splodges are no longer the first thing you see in my bathroom and I am so freaking excited.

Will look to reapply a few times in the coming week but feel this has been the miracle product I needed that will help me retain my deposit!

Thank you so much for all your advice - will look into the ventilation as a likely source. But at least I can keep on top of this now! x

I used this in a bathroom that had major black mould issues. It's definitely one of the better products on sale. Cheaper in Tescos than Morrison's.

Whilst treating the mould is a start you do need to address why it is growing in the first place as it will only reappear again.
