So my dog decided to have a field day on a bare double mattress in the spare room after a muddy walk.
I thought the muddy paw prints would come off easily, but no such luck - I've tried ordinary soap, washing powder, ktichen/bathroom sprays, but these prints just aren't lifting from the mattress! There is no cover that I can unzip and remove to wash. It's a bog standard sprung mattress, not expensive.
What should I try next?
