Is it safe to clean a mouldy mattress or should I throw it away?

Mouldy mattresses are extremely difficult to fully disinfect, especially when moisture or urine has soaked deep into the materials or internal framing. Even if you try to clean the surface, the lingering presence of mould and deep contamination often makes throwing it out the only safe choice.
