Help me clean my cushions

[MotherOfDragon]

I have a massive cushion in the garden on an egg swinging chair. Being an idiot I left it out over winter and my white cushion is green and black, I have sprayed with bleach and left in the sun, plus tried the same with Zoflora. The cushion doesn't come off to go in the wash. What do I do?!?

would the whole cushion fit in a large machine at the launderette?

Could you re-cover it? Or if not you, then a friend with a sewing machine? I'd guess it's mould and probably won't clean off, but should be fairly easy to cover.

No it wouldn't fit in a machine. I do t know anyone who can sew (well) either

You could try to dye it a dark colour?
