Wash TOMS in Washer: Safe Machine Care Guide

If you are staring at a pair of grimy, odor-filled slip-ons and wondering, can you wash TOMS shoes in the washer?, the clinical answer is yes. Classic canvas TOMS can survive a machine cycle, provided you strictly control the thermal and chemical environment. As a textile scientist, I see dozens of ruined shoes at the dry cleaning counter. Tossing canvas slip-ons directly into a top-loader with cheap detergent is a fast track to dissolved glue, cracked outsoles, and petrified insoles.

To save your shoes from structural failure, you must handle them with the same precision used for delicate garments. Here is the exact protocol to clean them without causing permanent damage.

1. The Anatomy of TOMS: Why Standard Washing Destroys Them

Understanding the material construction of your Alpargata-style slip-ons dictates exactly how they must be treated. Standard laundry habits chemically and physically degrade the shoe's key components.

• Cotton Duck Canvas (100% Cotton): This tightly woven exterior fabric is highly breathable. Exposing it to hot water shrinks the cotton fibers rapidly, warping the upper and making the shoes too tight to pull over your heel.
• Ethyl Vinyl Acetate (EVA) Outsole: The lightweight, flexible sole consists of an EVA copolymer. High temperatures melt or warp this material. Similar to the precautions required when you wash Hey Dude shoes, heat permanently ruins the flat structural profile of the sole.
• Suede Leather Insole: Classic TOMS feature a genuine, brushed animal-hide footbed. When saturated with water and standard laundry soap, the natural fatliquors (oils) in the leather leach out. As the water evaporates, capillary action forces the collagen fibers to stick together, leaving the footbed hard, rough, and cracked.
• Thermo-Reactive Adhesives: TOMS are held together with heat-sensitive shoe cement. Heavy-duty detergents often contain protease and amylase enzymes designed to break down organic proteins. These enzymes will actively eat away at the glue holding your shoes together, causing the sole to detach from the canvas.

3. Step-by-Step Instructions: Safely Washing TOMS in the Machine

Follow this precise 7-step method to clean your shoes without shrinking the fabric or stiffening the insoles.

Step 1: Dry-Brush Loose Debris

Never introduce water to caked dirt. Use a wild boar or horsehair bristle brush to sweep away loose dust, dried mud, and street grime from the canvas and outsoles. Skipping this step turns surface dirt into muddy water inside the washing machine drum, which deeply stains the white inner lining.

Step 2: Lock the Elastic Goring

The elastic "V" insert on the tongue provides the signature snug fit. Central washing machine agitators catch and violently stretch this elastic. Pin the elastic flat using a rust-proof safety pin, or apply a strip of water-resistant painter's tape over it to lock it in a relaxed position.

Step 3: Utilize a Micro-Mesh Bag

Place both shoes inside a micro-mesh laundry bag. This protects the cotton canvas from direct friction against the metal drum and stops the shoes from getting wedged under the door seal or agitator base.

Step 4: Create a Towel Buffer

Never wash heavy shoes alone. Add 3 to 4 old, clean, light-colored bath towels to the load. The towels act as a shock absorber. Without them, the shoes will violently bang against the drum walls. This action damages your washer's suspension, triggers unbalanced load errors, and subjects the shoe seams to excessive blunt force.

Step 5: Configure Chemistry and Settings

Much like the protocol required to wash Vans in the washer, you must keep parameters low and mild.

• Cycle: Delicate, Gentle, or Wool.
• Temperature: Strictly cold water between 20°C and 30°C (68°F to 86°F).
• Detergent: Add 1 tablespoon (15ml) of a mild, non-ionic liquid detergent. Check the label: Do not use biological detergents containing protease or amylase enzymes. Do not add fabric softener.

Step 6: Stuff and Shape Immediately

Remove the shoes from the mesh bag the exact moment the cycle completes. Do not wring or twist the canvas. Stuff the damp cavities tightly with clean, acid-free white tissue paper or adjustable plastic shoe trees. This absorbs internal moisture and forces the wet cotton canvas to retain its precise shape as it dries. Never use newspaper; the wet environment causes the carbon ink to bleed permanently into the footbed.

Step 7: Air-Dry with High Ventilation

Place the stuffed shoes in a warm room with high airflow, ideally directly in front of an oscillating fan. Allow 24 to 48 hours for total moisture evaporation. Keep them completely out of direct sunlight. UV rays degrade dyed canvas and make rubberized outsoles brittle.

4. The Laundry Lab: Chemistry, Odors, and Restoration

Once the washing process is complete, you will likely face two common issues: stiff suede and lingering odors. Here is the science behind fixing both.

The Suede Insole Restoration Technique

When your classic TOMS are 100% dry, the genuine suede footbed will feel hard and crusty. This happens because the water washed away the leather's natural oils, causing the microscopic collagen fibers to mat together. Take a brass-bristle suede brush or a clean pencil eraser and rub the insole firmly in small, tight circles. The mechanical friction breaks the temporary bonds between the fibers, lifting the nap and restoring the soft texture for barefoot wear.

Neutralizing Isovaleric Acid (Foot Odor)

If your shoes suffer from severe barefoot odor, traditional detergents only mask the smell with synthetic perfumes. Foot sweat contains isovaleric acid ($\ce{C5H10O2}$), which produces a rancid cheese-like smell.

Do not use fabric softener, which coats the canvas in a sweat-trapping silicone film. Instead, utilize sodium bicarbonate ($\ce{NaHCO3}$) to break down the acid chemically. Add 0.5 cup (120g) of baking soda directly to the washing machine drum before the cycle starts.

The reaction looks like this: $$\ce{NaHCO3 + C5H10O2 -> NaC5H9O2 + H2O + CO2^}$$

The baking soda reacts with the foul-smelling acid, converting it into an odorless sodium salt, water, and carbon dioxide gas that washes away cleanly.

Preventing the "Yellow Halo" Effect

A common complaint after washing white canvas shoes is the sudden appearance of yellow stains near the sole. This is alkaline detergent residue. When shoes air-dry too slowly, capillary action pulls leftover soap deep from the sole adhesives up to the surface of the white cotton. When UV light hits this alkaline residue, it oxidizes and turns yellow. Prevent this by using only 1 tablespoon (15ml) of liquid detergent, adding an extra rinse cycle to your machine, and drying the shoes strictly indoors with a high-speed fan.

5. Critical Mistakes to Avoid

Ruining a pair of canvas slip-ons usually comes down to three fatal errors. Keep these out of your routine entirely.

• Mistake 1: Chlorine Bleach. Liquid bleach contains sodium hypochlorite ($\ce{NaClO}$). While it seems like the logical choice for brightening dingy white canvas, chlorine chemically oxidizes the rubber cements used to bind the shoe together. This causes immediate yellowing along the seam lines and weakens the cotton duck fibers until they tear.
• Mistake 2: The Tumble Dryer. Whether dealing with canvas TOMS or reading a wash Allbirds guide, the dryer is the ultimate enemy of footwear. Temperatures inside a dryer easily exceed 60°C (140°F). This heat liquefies the structural shoe cement. The result is delamination-the bottom rubber sole peeling completely away from the fabric upper.
• Mistake 3: Dry Cleaning Solvents. Never take TOMS to a dry cleaner. Commercial dry cleaning utilizes perchloroethylene ($\ce{C2Cl4}$). This heavy solvent instantly dissolves synthetic adhesives and melts the EVA foam bottom of the shoe into a deformed mass.

6. Frequently Asked Questions

Can I put my TOMS in the dryer on the lowest setting?

No. Even low heat settings in a tumble dryer exceed the melting point of the thermo-reactive shoe cement holding the canvas to the sole. The shoes will delaminate, and the rubber will warp permanently. Always air-dry with a fan.

Why did my white TOMS turn yellow after washing?

Yellowing is caused by trapped alkaline detergent residue. As the shoe dries, water pulls the unrinsed soap to the canvas surface. Exposure to air and light oxidizes this residue, turning it yellow. Re-wash with cold water and zero detergent to rinse it out.

How do I get the smell out of TOMS without washing them?

Sprinkle 2 tablespoons (30g) of baking soda directly into the footbed of each dry shoe. Leave it undisturbed for 24 hours. The baking soda chemically neutralizes the acidic sweat. Vacuum the powder out completely the next day.

Can you wash TOMS with rope soles (Espadrilles)?

Never. Styles featuring a woven jute-rope midsole must be kept out of the washing machine. Water instantly saturates the natural plant fibers, causing them to swell, unravel, and harbor mold deep inside the rope. Spot-clean the canvas top only.

How do I fix the hard insole after washing my shoes?

The suede leather insole stiffens as water evaporates and binds the leather fibers together. Wait until the shoe is completely bone-dry, then scrub the footbed vigorously with a stiff brass suede brush. This breaks the stiffness and raises the soft nap.
