It’s still grungy. Toothbrush & paste?
How to super clean inside of vintage tea kettle?
I scored a bunch of copper bottom Revereware including a really dirty tea kettle. For the inside I boiled a bit of soap with full kettle of water for 10 mins. Now I’m going to use vinegar-water next boiling run. How much vinegar? What ratio? Should I add some salt too?
