Definitely playing it safe.
Thats why I am moving away from ethanol washes to a closed loop butane wash.
So what is this cooking grade butane you speak of.
I use Ventti butane myself and hear newport is also good. I have checked the MSDS on both and they are fine
Do you have a CLS yet? Haven't seen or heard of anyone in Aus with one. I'm sure I could do a search and see though
I have the small tamisium.
