I wouldnt use anything that burns, Anything that burns will have a residual from whatever fuel you are using. Thats just me and it maybe OK to use some of the mentioned form for heat but I wont do any of them. I used a kerosene heater to heat a garage once before I did any painting just to warm things up. The kerosene left a residue on everything and I had a lot of contamination issues.
I use electric now for my heat source.
