Aren't these "mould killers" a waste of money? I have a couple of rooms to redecorate that get very little ventilation so they've acquired some mildew. But would I not be just as well off by treating the surfaces with watery bleach prior to emulsioning?
You would be better served after doing that to add the triple solution of heat insulation and ventilation..

In my experience bleach doesn't help at all. The proper stuff is well worth using. I was given some by a damp specialist, sorry I don't know the brand.

I use a product by HG. It is the only one that seems to work. I have successfully removed mould from the shower. It takes a couple of applications, and seems to keep it at bay as well!
IME the "proper stuff" *is* bleach.
Most of the time I'd say that is what has been done here, but in one case the mould came back within a couple of months. The spores might be still viable and if the new surface gets damp it starts it all again. Brian
Yes all the bleach does is remove the current growth, not kill any airborne spores that might get on the wall if its not treated. I'd go for some kind of insulation and at least some ventilation as well. You probably cook with gas, that is your problem and there you are! :-)

I think Milton is pure hypochlorite. The household bleaches have other things in, like caustic soda etc
We get black mould around one window in our holiday let apartment. I can only speak as I find. Bleach certainly removes the surface black mould but does nothing to delay its return. Three weekly applications of the professional stuff has kept our problem area clear all season. The damp proof expert I got it from is off on a world tour at present, I'll get the name of the stuff on his return.

You need to fix the cause - poor ventilation and/or poor insulation and/or poor positioning of furniture against outside walls.
Bleach will kill it and take the colour out of it so you can't see it anymore. It has no long-lasting action against re-infection, and might well damage paint finishes too if there's still any residue left when you paint.
Fungicides will provide longer protection, but they are nasty chemicals which I personally don't want exposed around my home.
Hence, fix the cause.
Bleach removes it but quickly disappears. Lasting mould killers include copper sulphate, zinc zulphate, aspirin powder, borax, etc
