How do I use and care for Dish Sponges?Updated 4 hours ago

TL;DR: Dish Sponges are made from FSC wood-pulp cellulose. Wet them to expand, use like a normal sponge, wash gently (max 30 degrees), avoid bleach and softeners, and compost at end of life.

Why are these sponges different?

✓ Plant-fibre cellulose

Dish Sponges are made from natural wood pulp cellulose and cotton. They arrive dehydrated to reduce shipping volume and expand into a soft, absorbent sponge when you wet them. Because they're made from plant fibres, they're biodegradable and suitable for home composting.

How do I use them?

✓ Steps 1 and 2

1

Submerge the dehydrated sponge in water or hold under a running tap. It will expand to full size.

2

Apply cleaner to the sponge for washing dishes, wiping surfaces, or general cleaning.

✓ Steps 3 and 4

3

Rinse thoroughly after use and wring out excess water. Avoid twisting tightly to preserve the fibres.

4

If the sponge dries out between uses, simply re-hydrate by wetting it again.


How do I clean and care for them?

✓ Machine washing

Machine washable on a gentle or delicate cycle at cold to moderate temperatures (max 30 degrees). Air dry between uses. Direct sunlight helps drying and freshness where possible.

Max 30 degrees Gentle cycle Air dry

⚠ Avoid

Don't use bleach or fabric softeners. These reduce lifespan and affect compostability. Replace when excessively worn or if an odour develops.

No bleach No softener

Any quick tips to get more from them?

✓ Dry it out

Store so it can dry between uses. A dry sponge lasts longer.

✓ Heavy grease

Pre-treat with a little Dishwashing Liquid and warm water before scrubbing.

✓ Dedicate sponges

Keep one for delicate surfaces and another for heavy scrubbing. Both will last longer.


What are the specs?

✓ Materials and certifications

FSC wood pulp cellulose and cotton RoHS certified Made in China
