It's tinner. The heat comes trought faster. And near dissolve in watter. 
.. and free.
But it's difficult to print on it. As tend's to wrinkle. I just tape 
part of that thin paper on regular paper with masking tape.

I cut 6 circles about 5cm in diameter from "those green dish scour pads" 
and all stack to one M8 bolt. This gone to drill machine and does hard 
work of cleaning PCB. Just set drill to aprox 600rpm and push PCB 
against it. After cleaning turn board 90 degres and reclean.. 10 x 10 cm 
board cleaning time is aprox 2 minute. After that just wipe board with 
paper towel. (no solvents needed.)

..Much better than iron!
But I make hack on mine to heat up to about 180 degres centigrade. I 
make six pass without preheating board.
After etching I use stell ball (another kitchen cleaning item) like mesh 
of stell to rub toner out. Again NO solvent used. Just rub with stell 
mesh under watter.
