If the cushion covers can be removed they should be machine washable. For the inners, I would soak/ hand wash in a bath tub using something like Woolite or just a normal hand wash laundry soap. Baking soda and/or some vinegar in the water will also help reduce smells. Rinse well. You might need to do this several times depending on how dirty your water becomes. Then air dry in the sun, turning and plumping every so often to make sure it dries all the way through Answer from rosescentedgarden on reddit.com

r/CleaningTips on Reddit: How do I wash my sofa cushions?
August 6, 2021 -

I have a puppy, ergo pee everywhere.

She weed on my sofa recently and using an enzymatic spray is not getting the smell out. I think it needs a deeper clean. But there are no instructions in how to clean it (no tag and no instructions on the IKEA website that it is from).

I did however find the list of materials, which is:

Polyester wadding, Highly resilient polyurethane foam (cold foam) 35 kg/cu.m., Polyester fibre balls

I was going to outsource the task with dry cleaning but presumably it can't be dry cleaned if it's polyurethane? What would be the best way to wash this?
