How to clean P&T pram inserts?

[~*Niadalla*~]

I'm hoping to sell my pram Friday (someone messaged me 20 minutes ago asking about looking at it Friday), and I need to clean the red Vibe seat inserts. Is there an easy way? Just soak them? What in?
Any help greatly appreciated!!

I have a Beema Q and what I could put in the washing machine I did on a gentle wash. Everything else that was attached, I used sunlight soap and a bucket of water and scrubbed it down then rinsed it off. I see oyu are in Melbourne, so might be hard to get dried, unless you can put it under a heater vent or stand there with a hairdryer
