Stains
In the picture above are reusable organic cotton tea bags. They used to be off-white when they were new, but over time they acquired these magical colours and patterns from chamomile and green tea. These tea bags can be machine washed at 40 degrees, but I don't machine wash them for several reasons. One is that washing them with only water is sufficient, in my view. They stay very clean and dry quickly. Another reason is that the washing machines in our building are shared, and some fellow humans unfortunately still use scented detergents whose smells linger. I also wouldn't want to buy a separate wash bag for these tea bags so they don't get lost in the pile of clothing.
On my voluntary simplicity and zero-waste journey, I learned to embrace imperfections and see beauty in them. Imperfections such as stains, small holes, small cracks on cups and plates are good. Very often, when I see pictures of zero-waste objects, they look new. But it's so important to show what zero-waste living actually looks like.
As for using tea bags made from organic cotton, it does take longer to wash them and fill them with tea than to use a conventional tea bag. I use them as I try to avoid, as much as possible, plastics in my everyday life. I find natural materials more beautiful and pleasant. I also find living with less plastic slow and more mindful. And using less plastic aligns with the kind of society I describe and advocate for in my academic work. There are serious environmental concerns regarding the use of plastics, see for example this UN report.
