Don't toss that stained mattress out! Use Urine-Erase, an enzyme based product that effectively removes odors and stains, regardless of age (even 30-year-old set-in stain!). This stain remover works on mattresses, upholstery, wood floors, carpets, cement, leather, walls, etc. Manufactured since 1978, you won't find a better product to eliminate urine stains and odors.
Urine-Erases uses a two-step process. First, the dry enzyme powder is mixed with water. This enzyme solution is poured onto the stain, saturating for at least eight hours. Then, a second solution is applied to react with the enzyme and remove the stain. See the Additional Information tab to read more about how Urine-Erase works.
