So far the longest I've been able to make an atomiser last is a week. I've soaked them in alcohol, soaked them in water, used baking soda and vinegar to do the volcano method and the dry burn until the wick goes orange ten times wash and repeat method but nothing is making them last. Does anyone have any other suggestions? Haven't tried boiling them as that just seems a little extreme for electrical equipment but any other suggestions would be appreciated. I'm living in South Korea so it costs a lot to have them posted over and even more to buy them here so really need to find a method to make them last longer if possible. Thanks in advance.
