How to Wash TOMS: Safe Fabric Restoration Guide

If you are wondering how to wash TOMS without dissolving the internal adhesives or turning the suede insole into a rock-hard surface, the answer lies in strict temperature control and targeted hand-washing. As a textile scientist and professional dry cleaner with 20 years behind the counter, I regularly see clients bring in ruined canvas slip-ons. The damage is always identical: warped rubber soles, separated fabric, and a shriveled, stiff leather footbed.

Treating these shoes like standard athletic sneakers is a fast track to the trash bin. This guide outlines the exact, professional-grade protocols to extract dirt, neutralize odors, and restore your shoes safely.

The Quick Answer: How to Wash TOMS Safely

To clean canvas TOMS without ruining their structural integrity, always hand-wash. Do not submerge them in water or toss them in a washing machine.

1. Mix 2 cups (473 ml) of cold water ($<30^\circ\text{C} / 86^\circ\text{F}$) with 1 teaspoon (5 ml) of mild, pH-neutral liquid laundry detergent.
2. Gently scrub the exterior canvas using a soft-bristled Tampico fiber brush in small, circular motions to lift embedded soil.
3. Rinse by wiping down the canvas with a clean, damp microfiber cloth. Do not submerge the shoes under running water.
4. Deodorize the non-removable suede insole by dusting it heavily with sodium bicarbonate ($\ce{NaHCO3}$) to absorb acidic sweat.
5. Air-dry indoors away from direct heat or sunlight. Stuff the toe boxes with white tissue paper to maintain the shoe's shape while drying.

The Science of TOMS Materials (Why Standard Washing Fails)

To understand exactly how to wash TOMS effectively, you must analyze the layered materials that make up these iconic slip-ons. The anatomy of the shoe is highly sensitive to moisture and thermal energy.

The Structural Anatomy of a Classic Slip-On:

• Upper Level: Greige Cotton Canvas (Absorbs sweat, highly prone to shrinkage).
• Bonding Agent: Polychloroprene Adhesives (Heat-sensitive glues that melt easily).
• Interior Footbed: Vegetable-Tanned Suede (Permanently hardens if soaked in $\ce{H2O}$).
• Base Sole: EVA / Vulcanized Rubber (Warps under mechanical agitation and heat).

1. Greige Cotton Canvas & Bast Fibers

The classic upper is constructed from greige cotton canvas, which is a coarse, unbleached, loosely woven textile. Other seasonal models utilize natural bast fibers like hemp or linen. When these organic cellulosic fibers are saturated with hot water and subjected to the violent mechanical friction of a washing machine agitator, they undergo cellulosic shrinkage. The structural yarns tighten permanently. Once the shoe dries, the canvas will be significantly smaller, altering the fit completely.

2. Polychloroprene (Neoprene) Adhesives

TOMS are assembled using heat-sensitive polychloroprene adhesives to bond the fabric upper to the sole unit. Exposing these glues to high wash temperatures ($>40^\circ\text{C} / 104^\circ\text{F}$) or prolonged water submersion triggers hydrolytic degradation. The glue literally dissolves. This causes delamination, resulting in the sole peeling entirely away from the canvas.

3. Vegetable-Tanned Suede Insoles

Classic styles feature a non-removable leather or suede footbed. Vegetable-tanned leather is highly reactive to liquid saturation. Submerging the shoe in a basin or a washing machine strips the hide of its natural fats, oils, and tannins. As the water evaporates, the protein fibers contract. The insole warps, shrinks, and dries out into a rigid, rock-hard texture that makes walking incredibly uncomfortable.

4. Ethyl Vinyl Acetate (EVA) and Vulcanized Rubber Outsoles

The lightweight, flexible outsole consists of EVA (ethyl vinyl acetate) or vulcanized rubber. EVA is a copolymer with a low glass transition temperature (T_g). Placing these shoes in a tumble dryer or exposing them to high-heat hair dryers forces the polymer past its T_g, warping the outsole permanently and destroying the flat walking profile of the shoe.

Materials Needed for the Job

Before applying any water to the fabric, gather these professional-grade textile care tools:

• Tampico Fiber Brush or Horsehair Brush: Soft-to-medium natural bristles lift soil without tearing or pilling the woven warp and weft yarns.
• Crepe Brush: A specialized rubber-textured tool designed to lift and restore the nap of the suede footbed.
• Mild, pH-Neutral Liquid Detergent: Choose a formula free of optical brighteners, bleach, and harsh bio-enzymes.
• Sodium Bicarbonate ($\ce{NaHCO3}$ / Baking Soda): Required for dry moisture extraction and chemical odor neutralization.
• Microfiber Cloths: High-absorbency towels needed for rinsing the canvas via capillary action, avoiding oversaturation.
• Unprinted White Tissue Paper: White cotton washcloths work as well. You will use these to mold the shoe during the drying phase.

Step-by-Step Guide: How to Hand-Wash TOMS (Recommended Method)

Follow these seven scientifically backed steps to deep-clean your canvas footwear, preserve the structural adhesives, and eliminate footbed odors.

Step 1: Dry-Brush the Surface

Before introducing moisture, take your dry Tampico or horsehair brush and aggressively sweep away loose dirt, dust, and dried mud from the canvas. Applying water to dry mud instantly liquefies it, pushing the dark soil particulates deeper into the porous weave of the raw cotton. Brushing the fabric while completely dry is mandatory.

Step 2: Prepare the Cleaning Solution

In a small bowl, mix 2 cups (473 ml) of cold water ($<30^\circ\text{C} / 86^\circ\text{F}$) with 1 teaspoon (5 ml) of mild, pH-neutral liquid detergent. Verify that the water is strictly cold. Warm water accelerates thermal glue breakdown and fiber shrinkage.

Step 3: Scrub the Canvas Upper

Dip your soft-bristled brush into the detergent solution. Shake off the excess liquid so the bristles are damp, not dripping. Working in small, tight circular motions, gently scrub the canvas exterior. Focus heavily on high-friction areas like the toe box, where scuffs occur, and the heel counter.

Just as you would when you prepare to wash canvas bags, you must avoid over-saturating the textile. Work entirely on the surface. Do not scrub the delicate elastic "V" gore at the instep. Aggressive friction will snap the elastane threads, leaving the slip-on loose and baggy.

Step 4: Clean the Soles

Take a slightly firmer utility brush (or an old toothbrush) and dip it into the remaining soapy water. Scrub the dirt off the EVA or rubber sidewalls. Work carefully. Do not transfer the dirty, brown foam back onto the clean canvas upper.

Step 5: Rinse Using Capillary Action Control

Do not rinse your shoes under a running faucet. Instead, dip a clean microfiber cloth in plain cold water. Wring the cloth out aggressively until it is barely damp. Press the damp cloth firmly against the soapy canvas. This leverages capillary action, drawing out the alkaline soap residue and suspended dirt particles without soaking through to the interior suede insole. Repeat this blotting process until no soap bubbles remain.

Step 6: Target Footbed Odor (Zero-Moisture Method)

To treat a smelly interior footbed without destroying the leather, you must utilize basic chemistry. Foot odor is caused by anaerobic bacteria breaking down sweat into isovaleric acid and lactic acid.

The Fabric Lab Approach: Applying sodium bicarbonate ($\ce{NaHCO3}$) directly to the dry suede causes an acid-base reaction that eliminates the foul smell at a molecular level, rather than just masking it. $$\ce{NaHCO3 + CH3CH(OH)COOH -> NaCH3CH(OH)COO + H2O + CO2^}$$

• Lactic acid reacts with baking soda to form odorless sodium lactate, trace water, and carbon dioxide gas.

• Lightly dust the dry suede insole with a 1/8 inch (3 mm) layer of baking soda.

• Let it sit undisturbed for 4 to 6 hours to absorb trace moisture and neutralize the acids.

• Vacuum out the powder using a narrow crevice attachment.

• Vigorously rub the dry suede with a crepe brush or a small piece of 400-grit sandpaper to lift the flattened leather fibers and restore its velvety nap.

Step 7: Shape and Air-Dry

Immediately stuff the damp toe boxes with unprinted white tissue paper or clean white cotton washcloths. Wet cotton naturally contracts as water evaporates. The internal stuffing acts as a mold, stopping cellulosic shrinkage and preserving the classic silhouette of the shoe.

Place the shoes in a well-ventilated indoor space with good airflow. Do not place them in direct sunlight or near home radiators. Ultraviolet (UV) rays cause photo-oxidation, which fades colored dyes and yellows white canvas.

The Damage-Control Machine-Wash Method (Alternative)

Disclaimer: Machine washing is highly discouraged by textile scientists. The agitation weakens the canvas weave and shortens the lifespan of the shoe. If your shoes are severely soiled with heavy mud and you accept the risk of slight shrinkage, use this strict damage-control protocol.

Step 1: Prep and De-Grit

Remove all loose dirt using a stiff, dry brush. Flake away any caked mud from the tread. If your model features laces, extract them and wash them separately in a small bowl of soapy water.

Step 2: Use a Mesh Laundry Bag

Place both shoes inside a padded, zippered mesh laundry bag. Similar to the protective measures you take to wash Allbirds, the mesh bag buffers the shoes against the metal walls of the washing machine drum. This prevents the heel stitching from snagging and unraveling due to violent mechanical friction.

Step 3: Select Gentle, Cold Settings

Set your washing machine to the Delicates or Handwash Cycle. Select cold water ($<20^\circ\text{C} / 68^\circ\text{F}$) and adjust to the lowest possible spin speed (select "no spin" if your machine allows). High rotational spin speeds exert immense centrifugal force, stretching the wet canvas and tearing the bonded soles.

Step 4: Use Enzyme-Free Liquid Detergent

Add 1 tablespoon (15 ml) of mild, enzyme-free liquid detergent. Do not use powder detergents. Powders require warm water to dissolve completely; in a cold wash, they remain granular and leave stiff, white mineral streaks on dark canvas. Never add chlorine bleach or oxygen bleach.

Step 5: Shape and Air-Dry Immediately

The second the cycle finishes, extract the shoes from the machine. Letting them sit damp inside the dark, humid drum promotes rapid mildew growth. Stuff them immediately with dry white paper and air-dry indoors, just as outlined in the hand-washing section. Never subject the shoes to a clothes dryer.

Material-Specific Cleaning Protocols

Different upper materials require entirely different chemical agents. If you own similar casual footwear, you might also need to know how to wash Hey Dude shoes, as they often utilize similar canvas and suede blends. Consult this reference table before attempting to clean non-canvas models:

Fabric Preservation: Laundering Mistakes to Avoid

• Avoid Oxygen Bleach on Dyed Canvas: Do not apply sodium percarbonate ($\ce{2Na2CO3.3H2O2}$) or "Oxi" powders to colored, navy, or black models. The oxidizing agent strips the organic dyes aggressively, leaving permanent, patchy faded spots across the fabric.
• Never Submerge the Shoe: Complete immersion causes rapid hydrolytic degradation of the internal glues. Keep all moisture localized strictly to the outer canvas surface.
• Skip the Hairdryer: Direct heat application pushes the EVA outsole past its T_g (glass transition temperature). The sole will melt and deform while the cotton canvas shrinks unevenly, completely throwing off the alignment of the shoe.
• Never Dry Under Direct Sunlight: UV exposure triggers photo-oxidation. The ultraviolet radiation breaks down the chemical bonds in the fabric dye, rapidly fading dark colors while turning crisp white canvas into a dingy yellow.

Maintenance and Prevention Pro-Tips

The "Toe-Box Stuffing" Rule

Make it a permanent habit to stuff your shoes with clean, unprinted white tissue paper or a cedar shoe tree while they dry. As wet cotton canvas evaporates moisture, the yarns contract inward. The stuffing acts as an immovable internal frame, forcing the canvas to hold its correct dimensions so the shoes still fit your feet perfectly once completely dry.

Prevent Color Bleeding

Highly saturated colors like navy, crimson, and black are notoriously prone to capillary color bleeding when exposed to water. To stop this, spray the exterior canvas with a non-silicone, fluoropolymer-based fabric protectant before your very first wear, and reapply it after every wash. This lays down an invisible, hydrophobic barrier that locks the dye into the fibers and repels water-borne stains from the street.

Suede Insole Revitalization

If you accidentally soak the non-removable suede footbed and it dries stiff, do not throw the footwear away. Wait until the leather is 100% bone dry. Take a clean crepe brush or a piece of 400-grit (or higher) fine sandpaper and aggressively buff the footbed. This friction breaks apart the clumped protein fibers, lifts the flattened nap, and reopens the surface area, allowing the suede to absorb foot moisture comfortably again.

Manage the Shoe Microbiome

To prevent bacterial odors without subjecting your shoes to the stress of constant washing, treat the internal microbiome. Mist the dry interior toe box with a specialized spray containing zinc ricinoleate or Saccharomyces Ferment (a natural enzyme).

Unlike commercial shoe sprays that just mask sweat with cheap artificial fragrances, zinc ricinoleate is a highly effective chemical absorber. It binds chemically to the odor-causing nitrogen and sulfur compounds in foot sweat, trapping them permanently so they can no longer be detected by the human nose.

Frequently Asked Questions

Can I dry-clean my TOMS at home?

No. Home dry-cleaning kits rely on localized thermal energy and harsh chemical solvents. These solvents easily dissolve the vulcanized rubber and EVA outsoles, ruining the shoe.

Why did my white TOMS turn yellow after washing?

Yellowing occurs due to alkaline detergent residue or photo-oxidation from sunlight. If soap is not rinsed thoroughly, it migrates to the surface during drying, leaving yellow halos. Rinse again with a damp cloth and a 1:1 white vinegar and cold water solution.

How do I get mud stains out of classic canvas TOMS?

Always let the mud dry completely first. Scrubbing wet mud pushes the soil deep into the cotton weave. Flake off the dry mud with a stiff brush, then spot-treat any residual pigment stains with a mild soapy solution and a microfiber cloth.

Can I put my TOMS in the microwave or oven to dry them faster?

Absolutely not. The intense thermal energy immediately melts the EVA soles, liquefies the polychloroprene glues, and severely scorches the organic cotton canvas, creating a severe fire hazard and completely destroying the footwear.

Can I use bleach to clean the white soles?

Avoid liquid chlorine bleach, as it causes white rubber to turn yellow over time. Instead, apply a thick paste of sodium bicarbonate ($\ce{NaHCO3}$) and cold water to the rubber sidewalls, scrub with an old toothbrush, and wipe clean.
