Pro-er tip: Get cellulose/bio-degradable sponges so your used sponge trash won’t hang around the landfill for the next thousand years.
Get a dish brush so that they don’t need to be replaced at all! The ikea ones are really nice and have a built-in plastic scraper. Haven’t used a sponge in the last decade.
Hell yeah, I can get behind this. I can’t comment on the O-Cedar as I can’t get them here and information online is sparse, but the equivalent I get in Australia is made from cellulose and is biodegradable, apparently sadly not including the scourer (after some digging it’s coated in polyurethane).
There’s a store in my city called The Green Store that sells bio degradable kitchen stuff, and I accidentally found out they have an Australian website too:
I can’t see them online, but I usually get sponges that have loofah fibres attached to the sponge which I assume is cellulose. They also have coconut fibre in place of the loofah.
