Hello all, this is my first time steeping. I'm not really gonna go too deep on steeping at the moment, just wanted to steep the e juice that I bought online. I have an ultrasonic cleaner, specifically an iSonic P8420, model SPB25. It has a 25 minute max timer and a heater with a preset of 149F/65C. How long do I have the steep the e juice and do I keep pressing reset as I steep or let the Ultrasonic rest for a bit just incase it overheats or something? Do I also use the heater throughout the steeping process? I have a dropper with a dropper cap, do I leave the cap on or off? If I leave it on, is it safe and will it taste chemically?
