Can this mattress be saved?

Looking to clean my mattress fully.

I have tried Hydrogen Peroxide, vinegar and dishwashing soap, even shaving cream as I saw a tip that that could work. The mattress is currently wet and as you can see the stain is very visible. Granted, it is still wet from the solution so I hope it gets better.

Please suggest other things I can do.

All help would be appreciated.
