Meh.
Boiling will not take all that burnt crap off the coil, which is what you really want to do in a cleaning process. It will reduce the amount, but it won't be residue free (unless you have a bottom coil and you repeat a few cycles of dry-burn/rinse, which will bring the coil that much closer to death anyway)
I am happy with my balance of no wasted time and energy with cleaning, and my slight cost increase and love of a new fresh carto!
