Usually when the bottom of electrical sterilisers burn it’s because they’ve been run without enough water in the bottom. I’ve never used the baby brezer though so unsure if it’s the same
@Viktoria how do you get rid of the Milton tablet strong smell?
If you don’t want to use a microwave (as they’re so toxic lol) then a UV steriliser- we use the Nuby one and it’s amazing it’s dry and finished in 3 mins x
