uPVC windows are going black with mould.....please help.

[Slime]

Hi all,
I have a house full of uPVC double glazed windows, but, the plastic is starting to go black with mould.........and I can't seem to shift it.
It is much worse in the bathroom due to the inherent wetness of that room.
Any advice would be really good,

many thanks in advance,

Slime.

Ventilate ventilate ventilate. Its no secret. Try a weak bleach solution to get rid of the mould.

Thanks fella,
will give it a go, but, methinks the mould has been there for some years!
Is neat bleach too extreme?

Try a weak solution first and maybe build up to a stronger mix.

not much point trying to remove the mildew until you have cured the condensation and the house is dry.

Does anyone drape wet washing around the house and over radiators?

Do you have, and use, an extractor fan in the bathroom?

Thanks freddymercurystwin,
I'll try the bleach at the weekend & report back.

Thanks JohnD,
informative link, thanks.
And yes, at this time of year my wife drapes damp clothes on the rads and, because she feels the cold, she tends to close all windows when I'm not looking!
I have a bathroom extractor in the light but the window stays largely closed at this time of year. I'll show her this topic.

Many thanks to both of you,

Slime.

if she insists on causing incurable damp by draping wet washing around the house (she might as well throw buckets of water at the walls) the house will always be wet and no-one can help you.

Start saving up for a tumble-drier (or build a shelter for the washing line).

The bathroom fan needs to be run until the bathroom is dry. This can easily take half an hour. A bathroom extractor works best if the door and window are both shut (this is true).

Thanks again JohnD,
all taken on board.

And if you get a tumble dryer, make sure it is vented outside through the wall.
The condensing types are hopeless.
Worse still, I have seen people using normal ones just venting directly into the room.
