Hello, I have been using my clearomizers for a few days only, (still also on analogs as I am finding my feet), and now they are starting to taste a bit funny and one is getting low on juice. So if I want to re-fill it do I have to clean it out first, or can I top up with same flavour? I assume if I want to change new flavour etc I would have to clean it out first.
Thanks
Thanks
