Mine get cleaned once a week - i have to clean them else i suffer firing pin misery.
My idea of cleaning it is to throw it in a sink full of detergent and then clean the 510 and firing pin with a toothbrush; HRH's toothbrush is best for the job i find!
I run a bit of water thru the tube - there's no point in me trying to get rid of the flavour i vape since i vape it all day anyway. Quick dry with her hairdryer and a bit of deoxit on the spring, battery and firing pin and i'm good for another week.
I spend more time making
coils and farting about with atties than i do with Reo maintenance.
