How to Remove Urine from Mattress

Urine on Mattress: Act Fast and Don't Over-Wet

A urine-soaked mattress is one of the most common household cleaning emergencies — especially with young children or pets. The challenge is that you can't put a mattress in the washing machine, and over-wetting can cause mold to grow inside the foam. The key is to absorb as much urine as possible immediately, then use enzyme cleaner to break down the uric acid, and baking soda to absorb moisture and odor.

What You'll Need

• Rocco & Roxie Stain & Odor Eliminator Bundle
• Heinz White Vinegar
• Baking soda (generous amount)
• Microfiber cloths or old towels
• SafeRest Waterproof Mattress Protector (for future prevention)
• Vacuum
• Fan or hair dryer (cool setting)

Step-by-Step: Fresh Urine on Mattress

1. Blot immediately — absorb as much as possible. Use clean microfiber cloths or old towels to blot up as much urine as possible. Press firmly and lift — never rub. The more you absorb now, the less that soaks into the mattress foam.
2. Apply white vinegar. Spray or pour Heinz White Vinegar over the affected area. The acidity neutralizes the alkaline ammonia in urine. Let sit 5–10 minutes, then blot dry again.
3. Apply Rocco & Roxie Enzyme Cleaner. Spray Rocco & Roxie Stain & Odor Eliminator generously over the stained area. This enzyme formula breaks down uric acid crystals — the source of both the stain and the persistent odor. Let sit 15–20 minutes.
4. Blot dry again with clean cloths. Remove as much moisture as possible.
5. Cover generously with baking soda. Sprinkle a thick layer of baking soda over the entire affected area. Baking soda absorbs remaining moisture and neutralizes odor. Leave for at least 8 hours — overnight is ideal.
6. Vacuum up the baking soda thoroughly once completely dry.
7. Air dry completely with windows open and a fan running. You can also use a hair dryer on cool setting to speed up drying. Never put sheets back on until the mattress is completely dry.

For Dried Urine Stains on Mattress

1. Apply white vinegar to rehydrate the dried uric acid crystals. Let sit 10 minutes, then blot.
2. Apply Rocco & Roxie Enzyme Cleaner generously. Let sit 30 minutes — longer contact time is essential for dried urine.
3. Blot dry, then cover with a thick layer of baking soda. Leave overnight.
4. Vacuum and air dry completely. Repeat if any odor remains.

Prevent Future Accidents: Mattress Protector

The best solution for urine on mattresses — especially with children or pets — is prevention. A SafeRest Waterproof Mattress Protector creates a waterproof barrier that prevents urine from ever reaching the mattress. It's machine washable, noiseless, and fits like a fitted sheet. One accident without a protector can permanently damage a mattress — a protector is essential insurance.

Frequently Asked Questions

How do I get the urine smell out of a mattress permanently?

The smell comes from uric acid crystals that bond to mattress fibers. Only enzyme cleaners like Rocco & Roxie that contain uricase break down uric acid permanently. Combined with white vinegar and baking soda, this eliminates the odor at the source rather than masking it.

Can I use hydrogen peroxide on a mattress for urine?

Yes — hydrogen peroxide can help with urine stains on mattresses. Mix with a small amount of dish soap and apply carefully. However, it can lighten some mattress fabrics — test on a hidden area first. The enzyme cleaner + baking soda method is generally safer and more effective.

How long does it take for a mattress to dry after cleaning?

A mattress can take 6–12 hours to dry completely depending on how much liquid was applied and the ventilation in the room. Use a fan, open windows, and a hair dryer on cool setting to speed up drying. Never put bedding back on a damp mattress — it will develop mold inside the foam.
