mould on blackout curtains - how can I clean them?

[Treeleaf]

I added thick blackout linings to several curtains and these linings have now got mould on the side facing the windows due to condensation. The label on the linings say they can't be washed or dry cleaned... Does anyone have any experience of this or know how I can clean them?
(There was a thread on this exact subject a few years ago, but I think the answers were more geared to cleaning fabric curtains rather than the rubbery blackout coatings I'm dealing with.)
I'd be very grateful for any advice. Thank you!

If it's a rubberised material wipe it with soap on the sponge and then with bleach and then with clean water. You need to kill the mould, but you may not be able to remove the stain.

White vinegar is better for killing mould than bleach. So you could try brushing the mould with a nail brush or old toothbrush then wiping on some white vinegar to see if that works. Another thing would be Astonish Mould & Mildew Spray. It’s bloody excellent stuff but may stain so do a tiny discreet bit first just to check. Or a final thing would be a product called Mould Magic from a UK website called Must Have Ideas. It’s a gel. We used this on the rubber in our washing machine and it completely removed the mould without damaging the rubber one bit.

Wash well with soap and water followed up with vinegar. NOT BLEACH no matter how much my DMIL loves the stuff.

Vinegar and methylated spirit kill mould.

There are special mould removing sprays that you can try. This should kill the spores but is unlikely to remove any stains.

However, you really need to deal with the condensation:

Wipe off condensation every morning - this is key.
Heat.
Ventilate.

Otherwise this will become a recurring problem.

Thank you so much everyone. Really grateful for your advice.
