Your Kitchen Sponge Is Shedding Microplastics Onto Your Dishes.Here's What To Do About It.
Most people doing all the right things are still using a sponge that sheds microplastics onto their family's plates every single day.
5 Things You Need To Know About Your Kitchen Sponge
Your sponge is made of plastic. The kind that breaks off.
That green and yellow sponge by your sink? The yellow foam is polyurethane — a synthetic plastic. The green scourer pad is nylon or polyester fibres, woven together. Both are plastic. Both degrade with use.
As the foam compresses and the scourer abrades against pans and plates, tiny fragments break away. It's simply what happens when plastic wears down under friction and heat.

- Zero synthetic materials
- Fully compostable
Those fragments don't just go down the drain. They go on your dishes.
When plastic breaks off during washing, the fragments disperse into warm, soapy water — the same water going over your plates, pans, cups, and cutlery. Rinse thoroughly and most go down the drain. But not all.
Researchers have found microplastics in household dishwater, in food washed in contaminated water, and in the bodies of people who consume them. The kitchen sponge creates plastic contamination right at the point of food preparation.
Swift delivery and all with the absence of any horrible microplastics. Finally a sponge I feel good using on my kids' plates.

It's not one sponge. It's a continuous pipeline. The average UK household uses around 25 sponges a year — each spending its entire life degrading into sink water, then going into landfill. The microplastics it sheds are invisible. That doesn't mean they aren't happening.
The cost adds up too. At £1–2 per sponge, that's £25–50 a year on something you're constantly discarding. Seep's 12-month supply is £28.50 — one purchase, and because it's dishwasher-safe, each sponge lasts significantly longer.

The 12-month supply is where most people start. One purchase, no more constant replacing.
Shop the 12-Month SupplySeep is made from natural loofah and plant fibres. Nothing synthetic to shed.
Seep sponges are made from natural loofah — a plant, not a plastic. The sponge body uses plant-based cellulose. There are no synthetic materials anywhere in the product — nothing that can fragment into microplastics.
It's also dishwasher-safe, removing the main hygiene concern about eco sponges. Run it through a cycle and it comes out clean. That's why they last so much longer.
One 12-month supply. Dishwasher-safe. And it actually lasts.
This isn't a difficult swap. You don't need to change your routine. You replace one product with a better version of the same product — and stop putting microplastics into your sink water from that day forward.
Over 100,000 households have already made the switch. The most common thing people say afterwards? "Why did I leave it so long?"
I buy a box of 12 Seep eco sponges every year. Each sponge has a smooth side and a rougher side for pans. They are very effective and I wash them once a week, so they keep cleaner and last longer. Gentle on mugs and more delicate crockery, the rougher side does the job with pans. Easy to compost. I'd never go back to plastic sponges.
— Karen D'Rozario · Verified Customer · Eco Sponge Scourers (1 year supply - 12 sponges)These are absolutely brilliant! I've just received my second order. The first batch lasted well over a year. Not only do I use them for doing the washing up, I also use them for household cleaning in general. You can even wash them, which I discovered completely by accident. I highly recommend.
