mold stains under the mattress... skin problem for over a year, stubborn sores on the scalp...

Hello

I hadn't turned it over in a long time...

I used 2/3 lukewarm water and 1/3 hydrogen peroxide, sprayed it on, and rubbed it with a damp cloth after 5-10 minutes...

But the stains remain (see photo).

It's drying in the sun now...

The side I slept on wasn't moldy...

What should I do?

Thank you!!!
