Did you know that a lot of cleaning sponges and cloths contain plastic (I know right, wtf!) so whilst you're scrubbing away, little parts of your chosen cleaner are breaking off and going into the water system.
That means microplastics are potentially going to end up in the ocean, just from you doing some washing up! As soon as I discovered this I switched to a plastic-free sponge right away but unfortunately, the one I bought came wrapped in plastic (ahhh!).
That's why when I found plastic-free alternatives for cleaning I was SO happy - now I can get on with normal life without worrying about micro-plastics!
