Tossing sneakers in the dishwasher sounds clever until the glue dissolves at 145°F and the foam midsole compresses into a flat pancake. Washing shoes in dishwasher works for a narrow set of shoes (rubber Crocs, polyester soccer cleats, hard plastic sandals) and ruins the rest. Even the shoes that survive can contaminate your dishwasher with bacteria, detergent residue, and microscopic glue particles that get harder to flush than people realize. Before loading the rack, know what survives and what alternatives clean shoes better.

Why People Try This in the First Place
Dishwashers reach 130 to 165°F and use jets at 2 to 5 PSI, which intuitively seems perfect for grimy soles. The reality is that adhesives used in modern athletic shoes (polyurethane, EVA hot-melt, neoprene contact cement) start to soften between 140 and 160°F. Nike, Adidas, and New Balance all void warranty claims on shoes that have been machine-washed or dishwasher-washed.
That said, certain shoes really do clean up beautifully in a dishwasher. Crocs Classic Clogs, foam EVA flip-flops, polyester soccer cleats with molded TPU studs, and Vans Old Skool canvas sneakers handle a cool wash with no detergent. The key is matching the cycle to the shoe.
Shoes That Survive the Dishwasher
- Crocs Classic Clogs: All Croslite shoes are dishwasher-safe per the manufacturer FAQ.
- Foam slides and sandals (Adidas Adilette, Nike Benassi): Hold up well on a cool cycle.
- Soccer and lacrosse cleats with molded studs: Plastic and rubber tolerate the temperatures.
- Canvas Vans and Converse: Survive if the laces and insoles are removed first.
- Most flip-flops and pool slides under $25: Made of single-material EVA or rubber.
Shoes That Get Destroyed
- Running shoes with EVA midsoles: Brooks, Asics, Saucony, and Hoka all compress at high heat. Toss into a washer instead.
- Leather dress shoes: Heat warps the upper, dissolves leather conditioner, and ruins the welt stitching.
- Suede shoes: Water plus heat plus jet pressure equals permanent stiffening.
- Boots with stitched soles: The thread weakens and seams separate.
- Memory foam insoles: Crumble inside the shoe.
Step-by-Step for the Shoes That Can Take It
Limit dishwasher cleaning to once or twice per pair per season. Even safe shoes shorten lifespan with repeated dishwasher cycles.
- Remove laces and insoles. Wash these separately by hand in warm soapy water.
- Knock loose mud and grass into a trash can. Use an old toothbrush to clear deep tread.
- Place shoes on the top rack only. Bottom rack puts them too close to the heating element on Bosch, KitchenAid, and GE units.
- Skip the dishwasher pod or liquid. Detergent residue stays in foam and irritates skin.
- Disable the heated dry cycle. Select cool wash, gentle, or rinse-only.
- Run an empty hot wash with vinegar afterward to flush any glue or shoe residue from the dishwasher.
Sanitation Concerns Worth Knowing About
Shoe soles carry coliform bacteria, C. difficile spores, and dog feces residue at much higher rates than most people realize. A 2008 University of Arizona study found 421,000 bacteria on the outside of typical shoes, including 27 percent positive for fecal coliform. A standard 130°F dishwasher cycle kills most surface bacteria but does not fully sanitize.
If you must clean shoes in the dishwasher, never run dishes in the same load and run a full hot cycle with 2 cups of white vinegar afterward before any dish cycle. Skip this step and the next batch of glasses gets a coat of foot bacteria. Some homeowners keep a dedicated old dishwasher in the garage just for this purpose.
Better Alternatives for Most Shoes
Washing Machine Method
Most athletic shoes handle a washing machine better than a dishwasher. Place shoes in a mesh laundry bag, add 2 to 3 old towels for cushion, and run a cool delicate cycle with 1/4 cup of Tide Free or Method detergent. Air dry, never tumble.
Hand Cleaning Method
For leather, suede, and high-end running shoes, hand cleaning gives the best results. Use a brand-matched cleaner like Jason Markk Premium Shoe Cleaner ($16) or Reshoevn8r at $20. Apply with the brush, agitate gently, wipe with a microfiber cloth, and stuff with newspaper to dry. Total cleaning takes 15 minutes per pair.
Magic Eraser for Rubber Soles
Mr. Clean Magic Erasers (melamine foam) remove scuffs from white midsoles like nothing else. Wet the eraser, wipe in one direction, and the soles look new in 5 minutes. Skip the dishwasher entirely for this issue.
Smell Removal That Skips the Dishwasher
For shoe odor, fill a clean sock with 1/2 cup of baking soda, tie it off, and shove one into each shoe overnight. Repeat 2 to 3 nights for severe odor. For chronic foot odor, spray the inside of the shoe with a 50/50 mix of rubbing alcohol and water from a spray bottle, then let air dry 24 hours.
Cedar shoe trees from Stratton or Allen Edmonds ($35 to $90 per pair) absorb moisture and prevent odor in dress shoes. For athletic shoes, the Sof Sole Sneaker Balls ($6 for a 2-pack) tuck into the toe and freshen between wears.
When the Dishwasher Method Makes Sense
Dishwasher cleaning earns its place when you have a stack of muddy soccer cleats after Saturday games or a closet of Crocs that lived through a muddy garden weekend. For everything else, the washing machine or hand cleaning produces better results without risking the shoes or the dishwasher.
Warranty Notes Worth Reading
Bosch, Whirlpool, KitchenAid, GE, and Samsung all explicitly exclude warranty coverage for damage caused by washing non-dish items in the dishwasher. If a glue residue clogs your drain pump or a heating element fails after 50 shoe cycles, expect the manufacturer to deny the claim. A replacement drain pump runs $180 to $320 in parts plus $150 to $250 in labor, which exceeds the cost of buying new shoes outright.
Read your appliance manual. Most modern dishwashers explicitly list approved items, and shoes are not among them. Washing shoes in dishwasher is a niche tool, not the all-purpose solution social media makes it out to be, and matching the method to the shoe saves money on replacements.
