Help with cleaning mattress

[WhyDoesItAlways]

Looking for a bit of advice.

My mattress has a few sex stains marks on it which I need to get rid of as we are getting rid of the mattress and PIL want it for their spare bed

Anyone have any advice to get them out?

Try giving the stains a good scrub with plenty of soap and a little hot water, then sprinkle generously with bicarbonate of soda, rub to a paste and leave it to dry. Once dry, brush off or vacuum it.

Agree with PP. you could also try some kind of upholstery/carpet cleaner. I use the Astonish one on my sofa and it works well.

I have two mattress protectors on my mattress to stop any stains. Just cheap ones from Primark but doubling them up works well.
