Also there's sterilising bags and you can sterilise in the microwave with the right steriliser ;)
If I need asap, I'll use a kitchen towel x
We use sterilising bags that take 3 minutes in the microwave then set bottles upside down on kitchen paper to dry 😊 They come out of the bag pretty hot so they air dry pretty quickly.
I use a drying rack and let air dry. If needed paper towel but only if there's no other solution. Just bear in mind that you are sterilising against the worst of it (salmonella, listeria...) but domestic contamination is inevitable. And luckily for us it's not that dangerous. Sterilise and leave air dry, if necessary dry with paper towel. You are doing great!
