Common cleaning sponge found to release trillions of microplastic fibers

It’s the magic eraser sponges.

Isnt that just like a super really fine sand paper? If so are people really that surprised about this finding?

They’re very very fine foam, of melamine formaldehyde. The stuff of most whiteboards and some other white plastics. 

The foam is microscopic, and mostly air. The plastic substance of it is very hard but since the foam is all interconnected, in a macro sense it feels “soft” because it can be squished. 

You are correct. It behaves as sandpaper essentially, since its microstructure is so fine and at that level hard shards. 

But most importantly the foam breaks apart when absorbing foreign material, shredding itself into little piles and disintegrating into incapable microplastics.

I feel like if you’ve ever used one, this for sure would go through your mind.

And all other sponges. Includes Scrub Daddy. They're all depositing microplastics just at different degrees of intensity.

Natural Loofahs are the best organic alternative. If you live in a warm enough climate you can grow them yourself.

Loofas can even be grown in Canada. If one wants to purchase one, ask around on marketplace or in gardening groups locally. People are so happy to buy/sell locally!

Our family made the switch to cellulose sponges recently. Yes, they do wear out faster than plastic sponges but we get big packs (not expensive) and the peace of mind it brings knowing we're not contributing to the microplastic problem is most important for us. For abrasive sponges (which we don't use often), we have the thin sponges made of mostly coconut fiber.

Having recently bought a 4 pack, what would be the best course of action? Use them up? Don't use them? Dispose of them how? Is it more wasteful to just throw them away unused? Use them and then don't buy again? Sorry that's a lot of questions! But from an eco / environment point of view, what's the best option?

[u/GnrlPrinciple → u/Huge-Complaint7191]

Out of my depth for a a more scientific answer but for me personally what I did was: Wear a mask and plastic gloves while using. Don’t use them on anything remotely related to where me or a pet would breathe (sneakers mostly). And search for alternatives (the comments have mentioned a few ) . Other than that, I’m also just a fellow human trying to avoid plastic in general as much as a reasonably can 🤷‍♂️

[u/goreyEww]

That’s literally how it works…

[u/AntiqueScissors → u/goreyEww]

Yeah, when we’re scrubbing and the sponge keeps getting smaller and smaller, where do people think it’s going?

[u/Bloodthirsty_Kirby → u/AntiqueScissors]

That's the ~*~Magic~*~ part

[u/Imfrank123]

You mean those things that turn to dust the second you start scrubbing something? I’m shocked!

[u/Jeffde → u/Imfrank123]

Sponge smoke!… don’t breathe this!

I hope to see more of a step towards being more eco-conscious in the cleaning community. Sharing these kinds of articles will hopefully get people at least thinking about the products they use.

[u/leeski → u/rusticgoblin]

I agree! Once I started learning about this stuff I was really alarmed by the types of products I was regularly using.

My sister has this blog in case anyone is interested - not trying to self-promote - I'm just really proud of her as she actually doe the research, doesn't use AI to write copy, and is super passionate about educating others.

So just sharing as a resource in case anyone else is like me and gets overwhelmed on where to get started. The top portion is educating about the different chemicals and stuff but further down has product recommendations.

Does it get washed away after rinsing?

Just curious.

Sucks for the environment tho

In other news today, water: wet.

Five month old article that was already posted to this sub. 

[u/GnrlPrinciple]

I’m kinda floored by how many people think that because they don’t wash something they eat from, that means they are fine. Wowzers.

[u/cozycorner]

They are melamine. I don’t know why this was a new discovery.

[u/RevolutionaryAlps205]

It seems like the thing you would want to know is whether this is an appreciable addition of microplastics on top of everything else further upstream in the chain of food production. 

If it's a .0002 increase it is what it is. But if it's appreciable in proportion to everything else, it's probably a good idea to at least think about washing your pet food bowls with paper towels.

I don't really consider this a huge problem. I use them to clean scuffs off of paint. Wear gloves, wipe the surface with something else after, don't use them to do your dishes.

[u/Internal_Quail3960]

well if you want to get really specific, there’s already microplastics in everything. even newborn babies have microplastics in their bodies fresh out of the womb

[u/More_Bookkeeper_1407]

Scrub daddy does too I think
