Tested: How To Get Vomit Out Of Sneakers Fast (2026)

By David Park · November 27, 2025

Immediate Action (first 5 minutes)

Your kid gets carsick on the way to soccer practice. Or maybe your buddy had one too many IPAs at the local brewery and hurled right on your prized sneakers. Either way, panic sets in. I've been cleaning shoes professionally for six years, and I can tell you that stomach acid is brutal. It eats through adhesives and sets into mesh fibers faster than almost any other biological stain. You have exactly five minutes before the damage becomes permanent.

First, grab a dull edge. I usually use a plastic spatula or an old credit card. Scrape off the solid chunks immediately. Don't press down. You'll just push the acidic mess deeper into the toe box mesh. Next, grab a dry paper towel and gently blot the remaining moisture. Never rub. Rubbing spreads the bacteria and grinds the proteins into the fabric. Finally, run the affected area under cold tap water for exactly 60 seconds. Hot water will cook the proteins, basically baking the smell into your shoes forever.

Stomach acid has a pH between 1.5 and 3.5. That is highly acidic. It literally breaks down the polyurethane glue holding your midsole together. If you skip this immediate cold-water rinse, the acid will continue to eat away at the structural integrity of the shoe. I've seen $200 running shoes completely delaminate because the owner let the acid sit for an hour.

What You'll Need (tools/products)

You can't just use regular laundry detergent for this. Biological stains require biological cleaners. I've tested dozens of products on my own ruined pairs, and enzyme-based cleaners are the only things that actually break down the proteins. Here is the exact kit I keep in my cleaning caddy.

Product	Purpose	Price Range
Biokleen Bac-Out Stain & Odor Remover (32oz)	Live enzyme culture to eat proteins	$14.99 - $16.50
Reshoevn8r Soft Brush (3/4 inch bristles)	Gentle agitation for knit and mesh	$12.95
Meguiar's Supreme Shine Microfiber Towels (3-pack)	Extracting moisture without scratching	$8.99
FunkAway Aerosol (8oz)	Neutralizing lingering odors in the insole	$9.99

I'll be honest, this takes elbow grease. You can't just spray and walk away. If you have kids who track mud everywhere and occasionally get carsick, you'll need to master this technique. The Reshoevn8r brush is my favorite because the soft hog hair bristles won't pill delicate Flyknit or Primeknit materials. Cheap plastic bristle brushes from the dollar store will destroy your shoe's upper in seconds.

Step-by-Step Removal

Once you've handled the initial panic and gathered your supplies, it's time to do the deep clean. Follow these five steps exactly. I've used this exact method to save a pair of New Balance 990v5s that my dog threw up on after eating grass.

Step 1: Disassemble the shoe completely

Take out the laces. Pull out the insoles. I've seen too many people skip this crucial step. Vomit seeps under the insole and rots the midsole glue from the inside out. Toss the laces into a mesh laundry bag and run them through your washing machine on a cold cycle. For the insoles, soak them in a plastic bucket filled with cold water and two scoops of OxiClean for 45 minutes. If the vomit soaked entirely through the insole, just throw them away and buy a $15 replacement pair from Dr. Scholl's. It's not worth the risk of lingering bacteria.

Step 2: Saturate with enzyme cleaner

Shake your bottle of Biokleen Bac-Out vigorously. Spray the affected area heavily until the fabric is completely saturated. The enzymes need moisture to survive and eat the proteins. Let it sit for exactly 15 minutes. Don't let it dry out. If you live in a dry climate, spray it again at the 7-minute mark. You'll notice the cleaner starts to foam slightly. That means it's working.

Step 3: Agitate with a soft brush

Take your soft-bristled brush and work the cleaner into the fibers. Use small, circular motions. Apply very light pressure. You want to lift the stain, not scrub it deeper into the backing material. Spend about 3 minutes brushing the area. Pay special attention to the seams and the stitching around the toe box, as this is where gunk loves to hide.

Step 4: Extract and rinse

Grab your microfiber towel and press it firmly into the wet area. You want to absorb as much of the dirty enzyme water as possible. Rinse the towel in cold water and repeat until the suds are gone. If you own a wet/dry shop vac, use the upholstery attachment to suck the moisture out. This cuts drying time in half and pulls deep-seated bacteria out of the foam padding.

Step 5: Air dry properly

Never put your shoes in the dryer. The heat will melt the glue and shrink the shoe. Instead, crumple up dry newspaper and stuff it tightly into the toe box and heel. The paper absorbs moisture from the inside while maintaining the shoe's shape. Place the shoes in a well-ventilated room with a fan pointing at them. Keep them out of direct sunlight, as UV rays can yellow the white rubber midsoles. Change the newspaper every 2 hours for the first 6 hours. Expect a full 24-hour drying time.

Alternative Methods

Sometimes you don't have an enzyme cleaner on hand, or the stain is on a tricky material. Here are three backup methods I've used when I was in a pinch.

Method 1: Baking Soda and White Vinegar Paste

If you're stuck at a hotel or a friend's house, head to the kitchen. Mix three tablespoons of baking soda with one tablespoon of white vinegar. It will fizz aggressively. Stir it into a thick paste and smear it over the stain. Let it dry completely, which usually takes about 45 minutes. Once it's hard and crusty, use an old toothbrush to knock the dried paste off. The baking soda absorbs the odor, while the mild acidity of the vinegar breaks down the biological matter. It's not as effective as live enzymes, but it works in an emergency.

Method 2: The Washing Machine (Canvas Only)

If the vomit is on a pair of canvas Converse or Vans, you can use your washing machine. I only recommend this for 100% canvas shoes with no leather or suede accents. Put the shoes inside a thick pillowcase and tie the end shut. This stops them from banging against the drum and damaging your machine. Add a half-cup of white vinegar to the detergent dispenser. Run a delicate cycle with cold water. Air dry them outside in the shade. Don't do this with running shoes or basketball sneakers, as the agitation will destroy the structural foam.

Method 3: Ozone Generator for Lingering Smells

If you cleaned the stain but the shoe still smells like a brewery floor, the odor has penetrated the deep foam. Buy a cheap portable ozone generator on Amazon for around $45. Put the shoes in a small closet or a large plastic storage tote. Place the ozone machine inside, turn it on, and seal the space. Let it run for 30 minutes. Ozone (O3) literally alters the chemical structure of odor molecules. Just make sure you and your pets leave the room while it's running, as breathing ozone is harmful.

Prevention Tips

You can't always predict when someone is going to get sick, but you can make your shoes much easier to clean when it happens. I treat all my daily beaters with a hydrophobic spray.

Apply a Waterproofer: I use Crep Protect ($22 for a 5.5oz can). Spray it evenly from 8 inches away. It creates an invisible barrier that causes liquids to bead up and roll off. If someone pukes on your treated shoes, the mess will literally slide right off the mesh.
Reapply Monthly: The coating wears off after about four weeks of daily wear. Set a reminder on your phone to re-spray your favorite pairs on the first Sunday of every month.
Know When to Take Them Off: If you're at a party and your friend looks pale and sweaty, take your expensive Jordans off and put on some cheap $20 slip-ons from Target. It's much easier to throw away a cheap pair of shoes than to cry over ruined grails.

FAQ

Can I use bleach to kill the bacteria?

No, you should never use bleach on sneakers. Bleach will permanently yellow the rubber midsoles and weaken the polyurethane glue holding the shoe together. It also breaks down the synthetic fibers in mesh uppers, causing them to tear easily. Stick to enzyme cleaners or oxygen-based bleaches like OxiClean.

What if the vomit got on suede or nubuck?

Suede is an absolute nightmare to clean, and I'll be honest, the texture might be permanently altered. Blot the moisture immediately, then use a specialized suede eraser to rub away the dried crust. Once it's completely dry, brush it vigorously with a brass-bristled suede brush to restore the nap. If the acid burned the dye, you'll need to use a suede renovator spray to recolor the spot.

How long will the smell last if I just use soap and water?

If you only use regular soap, the smell will likely last forever. Soap lifts surface dirt but does not break down the complex proteins and stomach acids causing the odor. Every time your feet sweat and warm up the shoe, the dormant bacteria will reactivate and stink up the room. You must use an enzyme cleaner to completely eliminate the source.

Is it safe to put the shoes in the dryer on low heat?

Never put your sneakers in the dryer, even on the lowest heat setting. The tumbling action will warp the heel counter, and the heat will melt the adhesive bonding the outsole to the upper. Always air dry your shoes with newspaper stuffed inside to maintain their shape and structural integrity.
