Pet Urine on Mattress

timer

Pet urine contains proteins and ammonia compounds that bond quickly. Speed is critical — and so is preventing your pet from returning to the same spot.

checklistTreatment Steps

Step 1: Blot Up Liquid

Press clean paper towels firmly into the area to soak up as much urine as possible. Stand on them if needed. Replace until the towels come up dry.

Step 2: Rinse with Cold Water

Pour a small amount of cold water on the area and blot again. This dilutes the urine and pulls more of it out of the fibres or padding.

Step 3: Apply Enzyme Cleaner

Saturate the area with an enzyme-based pet stain cleaner. Enzymes break down the uric acid crystals that ordinary cleaners leave behind — this is what removes both the stain and the smell.

Step 4: Let It Work and Air Dry

Cover with a clean cloth and let the enzyme cleaner work for the full time stated on the bottle (often several hours). Air dry completely before allowing pets back on the area.

Step 5: Special Care for Mattress

After treatment, sprinkle baking soda generously across the area to absorb residual moisture and odours. Leave for at least 4–6 hours (ideally overnight), then vacuum thoroughly. Air the mattress before re-dressing.

Critical Warning

Mattresses cannot be saturated — excess liquid soaks into the foam or springs and causes mould, odours, and permanent damage. Use as little moisture as humanly possible. Never use a steam cleaner unless specifically rated for mattresses. Avoid bleach and harsh chemicals — they damage foam and leave residues you'll sleep on.

Pro Tip

Never use ammonia-based cleaners on pet urine — pets associate the smell with their own marking and will return to the same spot. Vinegar can mask the smell temporarily, but only enzymes fully eliminate it. — Use cold water only — heat can set proteins (sweat, urine, blood) and warm conditions encourage mould growth inside the mattress.
