hello
we forgot to check it was a smoke free home- lesson learnt 
the cover is removable and machine washable at 30 degrees.
any advice what i should put in with the wash and whether a soak is a good idea?
have read on internet about vinegar/bicarb/fabric conditioner/line drying- there's so many ideas, so i wanted to ask you wise people which is best!
need to do it today as am 38+4!!
many thanks!
