Pet Urine on Laminate and Vinyl Plank Floors: How to Clean It

Laminate and luxury vinyl plank (LVP) are popular with pet owners because they look like wood and are easy to wipe clean. Pet urine is still a problem for both, just in a different way than on carpet. The surface rarely absorbs it. The trouble starts when urine sits long enough to get into the seams between boards, the edges of laminate, or the underlayment and subfloor below. This guide covers what to do with a fresh accident, dried spots, and a smell that will not go away.

It follows the care guidance of flooring makers Mannington (laminate) and COREtec (luxury vinyl), and Humane World for Animals on pet stains and odors. Floors differ by brand and product line, so check your own floor’s care and warranty instructions first; they may name specific cleaners or rule some out.

Laminate or vinyl: which do you have?

Laminate has a photo layer on a core made of compressed wood fiber. The wear layer resists liquid, but the core can swell if water or urine gets into it through the seams or edges. Some newer laminates are sold as water resistant for a set time; check what yours is rated for.
Luxury vinyl plank and tile are made of vinyl, often on a rigid core. The boards themselves are usually waterproof, so the risk is urine running into the seams and collecting underneath, not the boards swelling.

If you do not know, look at the leftover boxes, the receipt, or an exposed edge at a doorway or vent.

Fresh accident: step by step

Act quickly. Mannington’s laminate care page says to promptly remove all liquid spills, including pet urine. The less time it sits, the less reaches the seams.
Blot, do not spread. COREtec advises blotting a wet spill right away with a white cloth or paper towel. Work from the outside in so you do not push urine into more seams.
Rinse the spot lightly. COREtec says to use a damp white cloth or paper towel to rinse any spill that is not water, then blot the area dry.
Clean with a product your floor allows. COREtec recommends only pH-neutral cleaners on its vinyl floors. For odor, use an enzymatic cleaner whose label says it is safe for your floor type, applied to a cloth rather than poured on. Humane World for Animals recommends enzymatic cleaners for pet urine, because they break down pet waste odors.
Dry it completely, including the seams and the edge along the baseboard.

Use as little liquid as you can. Mannington says never to flood the floor with water. A damp cloth is enough; a soaked mop pushes liquid into the joints.

Dried spots on vinyl

COREtec’s guidance for dried spots is to gently agitate the area with a damp white cloth and blot it dry. For stubborn marks, it suggests isopropyl (rubbing) alcohol on a white cloth, then rinsing and blotting. Test anything new on a hidden spot first, such as inside a closet.

When the smell will not go away

If the surface is clean but the room still smells of urine, the urine has most likely gone into the seams or under the floor. Signs to look for:

Raised, soft or swollen edges on laminate boards, or seams that have opened.
Dark lines along the joints or along the baseboard.
A smell that comes back on warm or humid days, or after mopping.
Glow under a black light along seams and edges. See how to find pet urine with a black light.

Cleaning the top surface cannot reach urine under the boards. Many floating laminate and click-lock vinyl floors can have individual boards lifted, so the underlayment and subfloor can be cleaned and dried, and swollen laminate boards replaced. That is a job for the installer or a flooring professional, especially if the urine has reached a wood subfloor. Keep spare boards from the original install for this.

What not to use

Vinegar on vinyl. COREtec lists detergent, vinegar, wax, citrus and floor polish among the products never to use on its LVP, noting that vinegar is slightly acidic. Humane World for Animals also advises avoiding vinegar and ammonia for pet urine, because strong chemical smells may encourage a pet to mark the same spot again.
Bleach and abrasive cleaners. COREtec rules out bleach-based and abrasive cleaners, and Mannington rules out abrasive cleaners, steel wool and scouring powder on laminate.
Soap-based detergents, wax and polish on laminate. Mannington says not to use soap-based detergents, and never to wax or polish its laminate.
Steam mops, unless your maker approves them. COREtec says to avoid steam mops unless the maker has approved them, and Mannington names the laminate collection it approves steam cleaners for (Restoration). Heat and steam can force moisture into the seams.
Soaking the floor. A wet mop or a bucket of water spreads urine into more joints.

Prevent the next one

Keep paper towels and a floor-safe enzyme cleaner where accidents usually happen.
Put a washable, waterproof-backed mat under litter boxes, water bowls and the spot near the door where a young or older dog may not make it outside.
Check the same corners with a black light every few weeks, since repeat spots tend to be in the same place.

Keep cleanup supplies ready

Our Pet Cleanup Kit has gloves, an enzyme odor product, an absorbent powder and a UV black light in one pouch, so you can blot, treat and check the seams before urine has time to soak in. Check the product label to confirm it suits your floor, and test it on a hidden spot first.

Frequently asked questions

Can dog pee ruin laminate flooring?

It can, if it sits long enough to reach the seams and the wood-fiber core, which can swell. Wiping it up promptly, as Mannington advises for all liquid spills including pet urine, prevents most damage.

Is luxury vinyl plank waterproof against pet urine?

The boards are usually waterproof, and COREtec describes its floors as waterproof and petproof. Urine can still run into the seams and collect under the floor if it is left, so clean it up quickly either way.

Can I use vinegar on laminate or vinyl floors?

Check your floor’s care guide. COREtec says never to use vinegar on its LVP, and Humane World for Animals advises against vinegar for pet urine because the smell may draw a pet back to the spot.

How do I get urine smell out from under laminate?

Surface cleaning will not reach it. The affected boards usually need to be lifted so the underlayment and subfloor can be cleaned and dried, and swollen boards replaced. Ask your installer or a flooring professional.
