Just moved into a house where these cream coloured curtains have been in situ for a long time and the linings have some rust-coloured "age spots"/possibly mould marks just at the bottom (see photo). About 90% of the linings are fine, but due to less-than-ideal condition, might be suitable for draft-proofing some kind of garden cabin/garage workshop or similar?

Or try to revive by dry cleaning? Or possibly wash in a commercial washing machine?

Thought I'd see if anyone can make use of them before resorting to textiles recycling at local recycling centre.

Happy to supply the original curtain tracker too, as it will be removed for redecorating.

There is also a smaller pair made of identical material that I'll be posting on here later today or tomorrow.
