Soak Sponge

Plastno's biodegradable cellulose sponge is a plant-based, plastic-free pop-up, sold in a 3-pack. Each sponge ships flat and compact, then expands the moment it hits water. Soft, ultra-absorbent, and free of the microplastics that conventional foam sponges shed in every wash.

The Soak Sponge replaces polyurethane and polyester foam sponges with plant-based cellulose for everyday kitchen cleanup. Use it on dishes, counters, sinks, glassware, and most hard surfaces. Gentle on non-stick cookware and most kitchen finishes, durable enough for daily use.

Rinse thoroughly and let it air-dry between uses. Boil it or run it through the dishwasher on the top rack once a week to sanitize. Each sponge lasts 2 to 6 months of daily use, and when it's worn out, it biodegrades in soil or a backyard compost pile with no plastic residue.

• 3 pop-up cellulose sponges per pack
• Pop-up format, ships flat and expands in water
