How to Remove Pet Urine from Upholstery
Blot fresh pet urine immediately with dry towels, apply a bio-enzymatic upholstery cleaner to break down uric acid crystals, let sit for 15 minutes, blot dry, and air out cushions.
Context
Conditions that change the method
- Delicate surface — Never saturate inner sofa cushion foam with excess water; trapped moisture in polyurethane foam causes deep internal mildew.
Avoid chemical mixing and protect respiratory health
Never mix ammonia or vinegar with chlorine bleach. Wear rubber gloves when handling bio-enzymatic sprays. If cleaning solution splashes into eyes or irritates skin, rinse immediately with clean water.
What you need
- Bio-enzymatic pet stain and odor remover
- Clean white microfiber towels or absorbent paper towels
- Baking soda (for final dry moisture absorption)
- Clean water in a spray bottle
- Heavy stack of books or weights
- Immediately fold a thick stack of clean paper towels or white microfiber cloths over the wet urine puddle and press down firmly to extract as much liquid as possible from the fabric and cushion.
- If the cushion cover has a zipper, unzip slightly and place a dry towel between the fabric cover and the inner foam to prevent the puddle from migrating into the core.
- Spray the affected fabric evenly with a bio-enzymatic cleaner until damp but not waterlogged.
- Allow the enzymatic cleaner to sit for 15 to 20 minutes while active bacteria digest the pungent uric acid salts and animal proteins.
- Press clean, dry towels firmly into the treated area to absorb the enzyme liquid and lifted urine residues.
- Sprinkle a light dusting of baking soda over the damp spot, let dry completely for several hours to pull out residual moisture and scent, then vacuum thoroughly.
What to avoid
- Never use a steam cleaner on pet urine stains; heat permanently cooks the protein and bonding acids into sofa upholstery fibers.
- Avoid ammonia-based household cleaners, which smell identical to urine to pets and trigger repeat marking.
- Do not pour cups of liquid cleaner directly into the couch cushion.
Products
What to use
- Enzyme cleanerA biological cleaner formulated with enzymes (proteases, lipases, amylases) that consume organic waste, uric acid crystals, and pet odors at the molecular level.
- Distilled white vinegarA mild acid useful for mineral deposits and some soap films on glass and other acid-safe surfaces. Never mix it with bleach or ammonia. It is a method, not a disinfectant claim.
- Baking sodaA mild alkali that makes a paste for grout lines. It lifts film with light abrasion. Do not mix it with vinegar as a cleaning trick — the fizz is the two canceling each other out.
- Microfiber clothA reusable cloth that lifts film and leftover moisture without scratching glass. Use a clean face of the cloth as residue comes off.

FAQ
Questions people ask
- What if pet urine has soaked deeply into the sofa cushion foam?
- Remove the cushion cover, take the foam core outside, apply an enzymatic cleaner deep into the affected foam zone, squeeze out excess liquid between thick towels, and let dry thoroughly in breezy air for 24–48 hours.
- Can I locate and treat an old, invisible dry pet urine spot on my sofa?
- Use a handheld ultraviolet (blacklight) flashlight in a darkened room; dried uric acid fluoresces bright yellow-green. Mark the outline with chalk and treat thoroughly with bio-enzymatic spray.
