How to Clean Rubber Sandals | Mild Soap, No Heat

Wash rubber sandals with warm water and a little clear laundry soap, using a soft brush or sponge, then air-dry them in the shade at room temperature.

Heat is what kills rubber sandals, not dirt. A pair left on a hot porch or tossed in a dryer can turn brittle and crack long before the tread wears out, so the routine below is built around water, mild soap, and patience. Manufacturers who make rubber footwear say the same thing: keep it gentle, keep it cool, and let the sandals dry on their own.

What You Need Before You Start

• Soft-bristled brush or dry cloth — for loose dirt
• Warm water — not hot
• Clear laundry soap or mild dish soap — a small amount is plenty
• Soft sponge — for the cleaning pass
• Microfiber cloth — for wiping rubber footwear dry after use

Skip abrasive scrubbers, stain removers, and strong detergents. They can discolor rubber, eat into adhesives, and dull printed or synthetic finishes.

How to Clean Rubber Sandals Step by Step

The standard method for textile, rubber, and other non-leather footwear is five steps, none involving soaking.

1. Use a dry, soft-bristled brush or dry soft cloth to remove loose dirt from the straps, footbed, and outsole.
2. Mix a small amount of clear laundry soap with warm water.
3. Dip a soft sponge into the solution and gently clean the affected areas.
4. Rinse the sponge with clean warm water, then wipe away the excess detergent.
5. Let the sandal air-dry in the shade at room temperature.

For natural rubber footwear, Viking Footwear recommends wiping after each use and drying with a microfiber cloth before putting the pair away. That single habit prevents most of the grime that turns into a cleaning project later.

Disinfecting, Insoles, and Stubborn Spots

Clorox states that synthetic shoes, plastic sandals, flip-flops, and rubber soles can be wiped with Clorox Disinfecting Wipes, subject to the product label and the footwear maker’s care instructions.

This applies to hard, nonporous synthetic or rubber surfaces — not leather, suede, unfinished fabric, decorative coatings, or glued materials, and Clorox says not to use it on leather boots. Test an inconspicuous spot first. “Rubber” rarely describes an entire sandal, and a strap, lining, or glued seam may not tolerate the wipe.

If your sandals have removable footbeds or insoles, pull them out and wash them separately only if their care instructions allow. Viking recommends washing removable insoles separately in lukewarm water, and cleaning heavily used footbeds with an antibacterial spray before letting them dry fully.

A white film across natural rubber is often blooming — natural oils and waxes rising to the surface, not dirt. A rubber-footwear buffing spray used per its label, followed by rubbing with a clean, dry, lint-free cloth, can clear it. Check your maker’s instructions first. If you are replacing a worn-out pair instead of reviving one, it helps to see which rubber sandals held up in testing.

Why Drying and Storage Decide How Long They Last

Air-drying at room temperature protects the rubber. XTRATUF states that artificial heat can make natural rubber brittle and cause deterioration and cracking, and notes that direct ultraviolet exposure and sub-zero temperatures can do the same.

Keep wet sandals off radiators, out of dryers, and away from heaters. Viking recommends air-drying at room temperature, avoiding artificial heat and direct sunlight, and storing the pair upright in a cool, dry place with air circulation. Never fold or crease rubber footwear in storage.

Make sure the whole sandal — especially footbeds and sole grooves — is completely dry before wearing it again. Trapped moisture feeds odor and microbial growth, and aggressive soaking can loosen adhesives or damage layered materials.

Note: this method is for rubber, plastic, and synthetic sandals. Leather and suede need different care, and disinfecting wipes should stay away from them unless the maker permits it.
