Can You Wash New Balance 574? Safe Cleaning Guide

If you are asking, can you wash New Balance 574 sneakers, the direct answer is yes-but never in a washing machine. The 574 is a multi-material construction featuring delicate cowhide suede, polyester mesh, and an EVA foam midsole. Submerging these shoes in a washing machine strips the natural oils from the suede, causes dye migration, and chemically degrades the structural adhesives that hold the sole together.

To save your favorite shoes, you must clean them by hand using targeted chemistry and specialized mechanical action. Here is the exact professional protocol to remove stains, lift organic soils, and restore the suede nap without causing permanent damage.

The Fabric Science: Anatomy of a New Balance 574

To clean the New Balance 574 without ruining its structural integrity, you must treat the shoe as a hybrid of organic protein fibers, synthetic polymers, and elastomers. Each material zone has conflicting chemical tolerances. Treating the whole shoe with a single cleaning solution guarantees damage.

Overlays: Chrome-Tanned Split Cowhide Suede

The colored panels on the toe box, heel, and eyestays are constructed from split cowhide. Suede is a delicate protein fiber matrix tanned with chromium salts to preserve its soft, velvety nap. It is highly vulnerable to moisture. Water saturation solubilizes the rich acid dyes and strips the natural fatliquors embedded in the leather. Once these oils are gone, the collagen fibers dry out, shrink, and fuse together, resulting in a cardboard-stiff texture and premature dry rot. Suede requires an acidic to neutral environment, typically between pH 4.5 and 5.5.

Underlays: Polyethylene Terephthalate (PET) Mesh

The breathable netting across the toe box and tongue is woven from synthetic polyester polymers. PET mesh is naturally hydrophobic (water-repellent) and highly durable, but its open-knit structure readily traps organic particulate matter, such as dead skin cells, airborne dust, and mud. While mesh can handle water, aggressive scrubbing with stiff brushes will cause the synthetic filaments to snag, pill, and tear.

Midsole: EVA Copolymer and TPU

The thick, shock-absorbing ENCAP midsole consists of compression-molded Ethylene-Vinyl Acetate (EVA) encased in a Thermoplastic Polyurethane (TPU) heel clip. These foam compounds sit below their glass transition temperature (T_g) during normal wear, keeping them firm yet elastic. They are bonded to the upper using polyurethane hot-melt adhesives.

When exposed to hot water and mechanical agitation in a washing machine, these adhesives undergo rapid hydrolysis. The water molecules ($\ce{H2O}$) break the chemical bonds of the glue, causing the sole to separate completely from the upper.

Different materials require distinct tools. Follow this strict material matrix when prepping your cleaning supplies.

The Scientific Cleaning Protocol

This zoned cleaning procedure isolates the water-sensitive suede from the synthetic mesh to preserve the shoe's aesthetic and structural integrity.

Step 1: Dry Preparation and Mechanical Soil Lifting

Never introduce water to a dirty suede shoe. Liquid turns loose dust into embedded mud, driving particulates deeper into the protein fibers.

• Action: Take a dry, natural crepe rubber brush and run it across the suede overlays in a single direction. The rubber creates static friction that pulls embedded dry soil out of the velvety nap without scratching the leather.
• Targeted Abrasions: For localized oily scuffs on the suede heel or toe cap, rub the area with a clean polymer suede eraser. The physical abrasion lifts the greasy residue by transferring it onto the crumbling eraser bits.

Step 2: The White Towel Spot Test

Before you clean New Balance 574 mesh panels, you must test the adjacent suede for tannin migration (dye bleeding).

• Action: Dampen a white split-polyester microfiber cloth with a single drop of water. Press it firmly against a hidden patch of colored suede, like the inner ankle collar.
• Analysis: If dye transfers onto the white cloth, the acid dyes are highly unstable. You must restrict your suede cleaning exclusively to the dry crepe brush. Applying any liquid will cause the dark suede dye to bleed permanently onto the light-colored PET mesh.

Step 3: Zoned Mesh Cleansing

The goal is to lift trapped dirt from the polyester mesh without letting moisture bleed into the surrounding suede borders. Similar to the delicate synthetic upper techniques required to wash Skechers shoes safely, precision is mandatory.

• The Formula: Mix 1 drop of a pH-neutral, dye-free surfactant (such as specialty sneaker cleaner or a mild baby shampoo) into 1 cup (240ml) of water heated between 30°C and 40°C.
• Action: Dip a soft-bristle toothbrush into the solution. Tap the brush handle against the rim of the bowl to shake off excess liquid; the bristles must be damp, not dripping. Work the brush over the PET mesh in tight, circular motions.
• Extraction: The surfactant will bind to the grease and dirt, lifting it into a visible foam. Immediately blot the dirty foam away with a dry microfiber cloth before the moisture wicks into the suede overlays.

Step 4: Suede Overlay Refreshing (If Wet Cleaning is Required)

If the dry crepe brush failed to remove heavy stains, proceed with a damp extraction.

• Action: Apply a specialized, pH-neutral suede shampoo directly to the damp bristles of a premium hog-hair brush. Do not apply water directly to the shoe.
• Action: Buff the suede in light, sweeping strokes. You must clean the entire suede panel evenly, edge to edge. Spot-cleaning an isolated patch of wet suede will result in a hard, visible water ring once the leather dries. Wipe away excess foam immediately with a dry cloth.

Step 5: Midsole and Outsole Restoration

The white EVA midsole requires mild abrasive friction to remove scuff marks.

• Action: Lightly dampen an open-cell melamine foam pad (commonly sold as a Magic Eraser) with clean water. Buff the white EVA foam and the rigid TPU heel clip. The micro-abrasive structure of the foam acts like ultra-fine sandpaper, shaving off superficial dirt and scuffs.
• Action: Switch to a stiff-bristle utility brush dipped in warm, soapy water to aggressively scrub the heavy carbon rubber tread on the outsole.

Step 6: Internal Hydrophobic Packing and Controlled Drying

Wet shoes lose their structural shape. Proper drying requires internal support and strict climate control, similar to the protocols used when you wash Allbirds wool runners to prevent fiber shrinkage.

• Action: Remove the laces and foam insoles. Stuff the internal cavity of the 574s tightly with white, unprinted paper towels. The dense paper absorbs internal moisture and forces the toe box to retain its domed shape.
• Safety Warning: Do not use newspaper. Moisture causes the carbon-based printing ink to bleed onto the interior mesh lining. Do not use wooden shoe trees. The mechanical tension of wood springs will over-stretch the wet suede, altering your shoe size permanently.
• Environment: Place the shoes in a dry room with active cross-ventilation (like a floor fan). Keep them far away from direct sunlight, central heating radiators, or hair dryers.

Step 7: Suede Nap Restoration

When wet suede dries, the individual protein fibers bind together, resulting in a flat, crusty texture. You must break these temporary bonds physically.

• Action: Wait exactly 24 hours until the shoes are bone dry. Take your dry crepe rubber brush and vigorously brush back and forth over all suede panels. This mechanical friction separates the clumped fibers, stands them upright, and restores the original plush, velvety hand-feel.

"Laundry Lab" Pro-Tips & Prevention

The Chemistry of Salt Neutralization

During winter, urban sidewalks are coated in de-icing salts like sodium chloride ($\ce{NaCl}$) and calcium chloride ($\ce{CaCl2}$). When salty slush soaks into the suede of your 574s and evaporates, it leaves behind a highly alkaline, scaly white crust. If ignored, the sharp salt crystals physically slice through the suede fibers every time you take a step.

You must neutralize the alkalinity. Mix 1 part distilled white vinegar (acetic acid) with 2 parts distilled water. Dampen a microfiber cloth with the acidic solution and dab the white tide lines. The acetic acid reacts with the alkaline impurities, breaking them down so they can be wiped away safely:

$$\ce{2CH3COOH + CaCO3 -> Ca(CH3COO)2 + H2O + CO2^}$$

The Post-Clean Fluoropolymer Seal

Once the shoes are clean, dry, and the nap is fully restored, apply a high-quality fluoropolymer-based hydrophobic protector spray. The spray lowers the surface energy of both the suede and the mesh. Because the surface energy of the treated shoe becomes lower than the surface tension of water or oil, liquids will bead up into perfect spheres and roll off the shoe rather than penetrating the fibers. Hold the aerosol can exactly 6 inches (15cm) away from the shoe and apply two light, even coats, allowing 1 hour of drying time between applications.

The Deodorizing Insole Bake

The removable foam insoles harbor heavy concentrations of volatile organic compounds (VOCs) generated by sweat and foot bacteria. Do not put the insoles in the washing machine. Instead, remove them, place them in a dry basin, and cover them generously with dry sodium bicarbonate ($\ce{NaHCO3}$), commonly known as baking soda. Allow the powder to sit undisturbed for 12 hours. The bicarbonate structure acts as an amphoteric chemical sponge, neutralizing and absorbing acidic odor molecules. Vacuum the powder off the insoles the next morning.

Mistakes to Avoid

• Applying Direct Heat: Never tumble dry or use a hair dryer on a New Balance 574. Forced hot air permanently denatures the protein structures in chrome-tanned suede, causing aggressive, irreversible shrinkage. Heat also warps the EVA midsole, ruining the arch support and overall fit.
• Using Degreasing Dish Soaps: The internet frequently recommends cleaning sneakers with heavy-duty dish soaps. Standard liquid dish soap is highly alkaline (measuring around pH 8 to pH 9) and contains aggressive degreasing agents. If dish soap touches the suede overlays, it will instantly strip the residual tanning oils from the split leather, leaving it brittle and highly susceptible to cracking. Just as you must exercise chemical caution when you wash Nike shoes featuring mixed suede and mesh, stick strictly to pH-neutral formulations.
• Using Brass Wire Brushes on Mesh: A brass-bristled utility brush is an excellent tool for reviving heavily matted, stubborn suede. However, dragging stiff brass wire across the PET mesh underlays will immediately fray the delicate synthetic filaments. Keep metal bristles restricted strictly to the leather panels.

Frequently Asked Questions

Can I wash New Balance 574s in a pillowcase on the delicate cycle?

No. While a pillowcase reduces physical abrasion, the washing machine still fully saturates the shoe. This saturation triggers adhesive hydrolysis, separates the sole, causes dark suede dyes to bleed into the light mesh, and permanently stiffens the leather.

How do you get dried mud off New Balance 574 suede?

Do not wipe wet mud. Allow the mud to dry completely into a solid crust. Use a stiff-bristle utility brush to flake off the heavy dry mud, then vigorously rub a dry suede eraser over the area to lift out the remaining dusty residue from the nap.

Is it safe to use dish soap to clean the mesh panels?

No. Standard household dish soaps are highly alkaline and formulated to strip heavy greases. If soapy water bleeds from the mesh into the adjacent suede borders, it will strip the leather's natural fatliquors, causing premature dry rot and cracking. Use pH-neutral surfactants.

How do I fix my New Balance 574 suede if it feels stiff after drying?

Stiffness occurs because wet suede fibers clump and fuse together as water evaporates. Wait until the shoe is completely dry, then vigorously scrub the affected panels with a natural crepe rubber brush. The mechanical friction breaks the temporary bonds and restores the velvety texture.
