Like a squeaky clean kettle but don’t want to have to scrub it?
You have two Wasteless options:
1. Throw in a used lemon and boil your full kettle a couple of times, letting it sit until all the nasties have lifted then rinse and you’re good to go. Or
2. Throw in a tablespoon of citric acid that you bought in your BYO container at #wastelesspantry then boil and rinse, no wait time for you next lovely cup of something yum!
