Steps for dried urine stains:

  1. Lightly rehydrate the area

    • Apply according to the product directions, or
    • Use a similar gentle water-and-soap solution as for fresh stains.

  • Use strong chemicals with caution
    Products like bleach or very harsh cleaners may discolor fabrics or degrade certain mattress materials.
