Hi, yesterday I went to my local department store to buy a steam cleaner (Vaporetta) to use for cleanig the bathroom/windows ect.. then last night I had the idea to try and clean a cartomiser with it, so I held the carto with a pair of plyers (so i dont get burned) over the nozzel of the steam cleaner for 6-10 seconds (had a towel underneath to catch all the crap) Result... A good as new carto, let it dry for 10 mins then filled with Juice and it worked really well, I even tried cleaning a cart that was over 6 months old and the filler was dark brown, came up good as new too!! so I spent the next 2 hours cleaning all my old cartos!!! and the best thing is the steamcleaner only cost 17 Euros ($25) I also cleaned my Itaste tank atty, egoT and a 510 dripping atty,all with excellent results. here is a Video I made.
