better use boiling-point-petrol (?) that is used to clean everything in and around the house..
in dutch its called washing petrol or boiling-point-petrol -> cause its boiling point = 100C..
BUT...
- it can hold half the warmth water can..
u need to double your flowrate to achieve the same results.
its FLAMMABLE!
it can be used way below -100C
its cheap!
