Garage Smells Like Skunk? What Actually Cuts the Odor

Skunk spray clings to concrete, cardboard and fabric. Air it out, wash what you can, then use a remover that breaks down the odor instead of masking it.

Quick answer

If your garage smells like skunk, open the doors, run a fan to push the air out and find where the odor is coming from, since a skunk may have sprayed outside or be living nearby. Wash hard surfaces with a peroxide and baking soda mix or a skunk odor remover, and launder or toss what soaked it up. If the smell is constant with a rotten-egg edge, treat it as a possible gas leak first.

Free fix vs. permanent fix

Free fix · 1 hour

Air out, find the source and scrub

  • Open the doors and run a fan out of the garage for several hours
  • Look for the source: a spot on the floor, a box or a skunk den
  • Scrub hard surfaces with a fresh peroxide, baking soda and dish soap mix
  • Wash fabric and discard soaked cardboard

How long it lasts: Often enough for a light odor. A heavy or repeat spray soaks into concrete and cardboard and returns when the air turns humid.

A skunk odor remover

Skunk spray is a sulfur oil that sticks to surfaces and revives when damp. Perfumed sprays only cover it. A remover made for skunk odor is designed to break down or bind those sulfur compounds, so the smell is removed where it sits instead of hidden. It also reaches places a brush cannot, such as shelves, cracks and rough concrete.

What to get: Skunk odor remover spray or concentrate

How long it lasts: It works where you apply it, so the smell does not creep back on a damp day.

Why it happens

1

A skunk sprayed close to the garage

A spray on the driveway or outside the door drifts in under the garage door seal. The smell can linger for weeks near the spot.

2

A skunk living in or under the garage

Skunks den in dry, quiet spaces under porches, sheds and garages. A den smells musky all the time, and the animal sprays whenever it is startled.

3

A pet that got sprayed

A dog or cat can bring the smell in on its coat, then leave it on a bed, a rug or the floor.

4

Porous things soaking it up

Cardboard, wood, rags, mats and unsealed concrete absorb the oil. They keep releasing the smell long after the skunk is gone, and more on humid days.

5

Something that is not a skunk

Natural gas and propane carry an added sulfur odorant that smells like rotten eggs, and a dead animal can smell similar. Rule these out first.

Try this first (free)

Do these in order, starting with the simplest.

  1. 1. Rule out gas first

    If the smell is strong, steady or stronger near a gas appliance, leave the garage, avoid light switches and call your gas company or 911 from outside.

  2. 2. Open up and push the air out

    Tool used: Box fan

    Open the main door and any side door, and set a box fan in the doorway blowing out. Run it for several hours. Keep the exhaust pointed away from the house.

  3. 3. Find the source

    Sniff along the floor, under shelves and inside boxes. Check under the garage and porch for a hole or a dug-out gap. If a skunk is living there, call wildlife control. Do not seal it in.

  4. 4. Wash fabric and toss soaked porous items

    Wash clothes and rugs in the hottest water the label allows, with regular detergent, and dry them outside if you can. Throw out soaked cardboard, rags and wood you cannot wash.

  5. 5. Scrub hard surfaces with the peroxide mix

    Tool used: 3% hydrogen peroxide, baking soda and dish soap

    In an open bucket, mix 1 quart of 3% hydrogen peroxide, 1/4 cup baking soda and 1 teaspoon of dish soap. Scrub concrete, shelves and tires, wait 5 minutes and rinse. Mix it fresh and never store it in a closed bottle. It can lighten fabric and paint, so test a small spot.

  6. 6. Treat what is left with a remover

    Tool used: Skunk odor remover

    For rough concrete, cracks, shelves and anything a brush cannot reach, spray a skunk odor remover as the label directs. Let it sit, then air the garage out again.

When free fixes aren't enough

A peroxide wash handles a light spray on sealed, hard surfaces. It struggles with porous materials like unsealed concrete, wood and cardboard, where the oil soaks deep and the smell returns on humid days. A skunk odor remover is designed to neutralize the sulfur compounds and can be sprayed where you cannot scrub. If the smell returns every few days after cleaning, a skunk is probably visiting or denning. Cleaning will not hold until it leaves, so call a wildlife professional. If an animal acts oddly in daylight, do not approach it. Call animal control, since skunks can carry rabies.

How we picked: How we picked: this page is based on wildlife-agency advice on skunks, cleaning guides for skunk odor, gas-safety guidance, and what owners report in reviews of odor removers. We do not test products by hand.

Hard or porous? Clean each surface the right way

  • Sealed concrete, metal and plastic: scrub with the peroxide mix and rinse.
  • Unsealed concrete: scrub, then spray a remover and let it sit.
  • Wood and cardboard: if soaked, replace them. Lightly sprayed wood can be treated with a remover.
  • Fabric: launder it and air-dry it outdoors.

Porch smells like skunk? Check underneath

A porch smell that comes back is usually a den. Look for a gap at the edge, fresh dirt, a musky odor that is strongest near one spot, or droppings. Leave the animal alone and call a wildlife professional. Local rules differ on how to remove a skunk, and sealing a den with animals inside is cruel and can make the smell worse.

What to skip

Tomato juice and perfumed air fresheners

Tomato juice does not neutralize skunk spray. It mostly tires your nose for a while. Air fresheners cover the smell without removing it, and the skunk odor returns underneath. Use a wash or remover that targets the sulfur compounds.

Frequently asked questions

Why does my garage smell like skunk when I have not seen one?
Skunks spray at night and move on. The spray can drift under the door, or an animal may be denning beneath the garage or a nearby porch. Check under and around for a hole or digging at the edges.
Why does my porch smell like skunk?
Skunks often den in the dark gap under porches, steps and decks. Look for a hole at the edge or a small dug-out opening. Call a wildlife professional rather than sealing it up. Trapped animals spray more, and young may be inside.
How long does skunk smell last in a garage?
A light odor can fade in days to a few weeks after a spray outside. It lasts longer if it soaked into cardboard or concrete, and it often returns on humid days. Neutralizing it works better than waiting.
Could the smell mean a gas leak?
It can. Gas companies add a rotten-egg odorant. If you smell it near a gas appliance, or it does not fade, leave and call from outside. If you are not sure, treat it as gas.
