Just a wet sponge would prob be fine. I wouldn’t soap it because it might be hard to get the soap out and eventually might smell . Just make sure they’re pulled all the way out and then let it dry , the heat of the car/windows down will dry them quickly :)
Dr Beckmann Upholstery cleaner is a literal dream! Use it on car seat and the high chair straps, actual magic. Only a couple of quid too x
