Yeah I know I been doingb it less than a month but I have put in some heavy practicing and research in that month. I have just tattooed my girlfriend, she's put a pic on face book and now all her mates are volunterring themselves to me (for tattoos). If I am using disposable needles, tips, grips and tubes do I need an autoclave? I have an ultrasonic bath left over form my days as a mobile phones repair specialist (for cleaning circuit boards after water damage) It looks the same as the ones I seen advertised. I know obviously when (not if) I open a shop I'd need one and the it never crossed my mind to ask previos scratchers about the hygeine / sterilization procedures they used I just don't wanna make anyone ill and start as I mean to go on?
