Black mould on painted wall

[crazymuseummumtobe]

We have black mould appearing on an inside wall (sodding rental properties). Can anyone recommend a cleaning solution to remove it, that won't damage the paintwork? I have Cillit Bang Black Mould Remover, but it says not to use on painted surfaces.
Thanks.

Astonish make a mould remover in a green bottle with a blue trigger. I've used this on painted walls with no problems. Spray on, leave for 10 mins and the mould disappears without needing much if any wiping.

I buy it in Home Bargains or B&M.

I've used cillit bang on painted walls, all as ineffective as the rest. Anti mould paint has helped a bit.

Just use a bleach solution. Loads cheaper and fewer chemicals to affect the paint. Mould removers just have bleach as one of the ingredients. Bleach should will kill the mould and should get rid of any staining.

I had to do this every week in my old house.

I used a damp cloth and the black cillit bang spray with no probs.

Yes HG Mould Remover spray. It was recommended to me by a plumber and is very high strength and effective. Make sure you protect your hands, use it when the room is empty as it's strong and fumey.

When you've cleaned off the mould, you probably should re-paint with anti-mould paint. That was the advice I had.

They sell HG mould spray in most DIY shops and online.

I use vinegar

Sorry - I just noticed your point about not damaging the paint work. No idea whether this spray fits that bill because it was recommended for a serious mould job so I was intended to do a hard scrub and a repaint anyway.

It's very high strength so may not fit the bill. You may need to google/read reviews on this for that question.

As a mould remover though, couldn't recommend it highly enough. Kills everything and then is easy to wipe it off.

Black mould will be condensation.

Do you drape wet washing indoors?

Does your bathroom have an effective extractor fan?

Black mould will be condensation.

Could also be the sign of a leak somewhere and mould and water wicking up stud partion walls.

Thanks for the tips, ladies. A very small amount of Cillit Bang on a clean cloth had certainly got rid of it for now, will just have to keep doing it.

It's the inside of the front wall of a terrace, nowhere near the bathroom (which is downstairs). Only condensation is from breathing while asleep! However, with a baby on the way, we won't be taking the agency's suggestion of sleeping with the window open!

is wet washing dried indoors?

does the bathroom have an effective extractor fan? (this is relevant even if downstairs)

a photo of the wall with something to show scale may give more clues. For example, damp patches may be caused by rainwater from spilling gutters or downpipes, or entering around windowframes or bays. Repairing a fault is better than treating the mould.

if its condensation open the windows in the morning and then close them at teatime so your room warms up for bedtime if you don't ventilate the room the mould will just keep coming back

Hot water, bleach and soap powder is what i use.

Glad you got the mould off. I remember spending a fortune on fancy anti mould applications. All gone now. It doesn't matter how far away from the source of condensation it is, it just forms on the coldest wall. Cooking, showering etc. Need open windows, extractors used frequently or whole house dehumidifier.

My son had this problem in his student bedroom. Mould is a health hazard, phone the council and speak to the environmental health dept and get the specific govt policy that relates to this and then quote it at the landlord/letting agent.
We had no further trouble once we had done this, because it it not your fault (but you do need better ventilation etc)
