Not too many people know about this simple trick to clean your coils. Z Vaper couldn’t have explained it better, I typically use a cup instead of a bowl but that’s the only difference. From personal use I can say it makes my coils last at least a month, Z Vaper said his coils last up to 3 months.

A parallel coil is like a quad coil but has more room for cotton. Instead of wrapping four individual coils you wrap two large coils that consist of two wires each. Wrapping one over of the other you get one big coil on each side which provides more heat which equals thicker/warmer clouds. Here is RIP Trippers full tutorial on parallel coil builds.
