How do I use and care for Dish Sponges?Updated 10 days ago
TL;DR: Dish Sponges are made from wood pulp cellulose. Wet them to expand, use like a normal sponge, machine wash gently (max 30°C), avoid bleach and softeners, and compost at end of life.
Why are these sponges different?
✓ Plant-fibre cellulose
Dish Sponges are made from 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?
✓ Step by step
Submerge the dehydrated sponge in water or hold under a running tap. It will expand to full size.
Apply cleaner to the sponge for washing dishes, wiping surfaces, or general cleaning.
Rinse thoroughly after use and wring out excess water. Avoid twisting tightly to preserve the fibres.
If the sponge dries out between uses, 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°C). Air dry between uses. Direct sunlight helps drying and freshness where possible.
⚠ Avoid
Don't use bleach or fabric softeners. They reduce lifespan and affect compostability. Replace when excessively worn or if an odour develops.
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.
