Jiggity, I've been using the same 4 atty's for the last 2 months. every week or so, I just soak the ones I am not currently using in a cup of 70 to 90 % IsoProyl alcohol for 5 minutes, take them out, blow them out, set them aside and and let them dry out. When they don't taste like alchohal when you draw on them, they are ready to go. This is what I do anyhow, you will find a lot of different opinions on this
Thanks,
Jeff~
