Wee stains on mattress

[PenguinBear]

Even though we have mattress protectors on the beds, there are some yellowy looking urine rings on ds's mattress.

Is there anyway to remove the stains?

Jif. It sounds unlikely but it works.

What do I do? Wet sponge and rub?

Yes, wet sponge, rub it in. Leave it for a couple of minutes and then rub lots more. Wipe off with a damp cloth and leave to dry. The Jif smell goes in a few days too.

Thank you, will try this!
