How to remove wee stains/odour on mattress

[lairyhegs]

Any tips please on how to remove wee stains/odour on mattress. Had one of those plastic backed cotton protectors but it had small splits in without my noticing and pee has seeped through. Have tried bicarb mix, scrubbing with washing powder etc. Could I use my Vax on it? Any ideas v much appreciated. Thanks.
