Koh Dish Sponges credentials

Are they compostable?

Yes. Koh Dish Sponges are made from wood pulp and are biodegradable and home-compostable. When worn out, pop them into your home compost bin (tear into smaller pieces first) or send them to an industrial composting facility if you have access to one. They aren't suitable for kerbside recycling because they're compostable, not recyclable.

✓ Home-compostable wood pulp

Yes. Dish Sponges are made from wood pulp, so they break down naturally and are suitable for home composting. When worn out, pop them into your home compost bin (tear into smaller pieces first) or send them to an industrial composting facility if you have access to one.

How do I dispose of them?

Remove large food scraps and rinse off stuck-on food. Tear into smaller pieces to help home compost bins break them down faster. Add to your compost heap or green bin and keep the pile aerated. Industrial composting works too if your local council offers organics collection. Cellulose sponges aren't suitable for standard kerbside recycling.

⚠ Not recyclable

Cellulose sponges aren't suitable for standard kerbside recycling. They're biodegradable and compostable rather than recyclable, so composting is the recommended end-of-life route. If you're unsure about local composting options, check with your council's organics service.


How long do they last?

With normal household use and proper care, a cellulose sponge typically lasts a few weeks. Real-world use indicates up to around 5 weeks depending on frequency and how well it's dried between uses. Replace when the sponge becomes ragged, permanently stained, or starts to break down. Dish Sponges are also machine-washable for a refresh between replacements.

Up to 5 weeks Dry between uses

✓ When to replace

Replace when the sponge becomes ragged, permanently stained, or starts to break down. A worn sponge is doing its job. It just means it's time for a fresh one.


How should I care for them?

Rinse and squeeze dry after each use. Remove trapped water and food. Store in a well-ventilated spot so the sponge air-dries between uses. Don't leave the sponge sitting in a full sink of water. For a deeper refresh, Dish Sponges are machine-washable. Sunlight on a ventilated rack also helps keep the sponge fresh.
