I got really into DIY when I started going zero waste. It’s cheaper to make it yourself but it’s not essential. I’m happy to discover that more and more items are available package free. This is dishwashing powder from @ceresbrunswick. I first bought it packaged from @thankyouaus so that I could refill into an appropriate container. I haven’t attempted DIY dishwashing powder simply because it’s convenient and easy to buy ready made and package free.
Side note: For package free living, containers become a careful long term consideration. The right container makes dispensing easier and means I won’t get my white powders mixed up
