A lot of people don't realize that there are two types of "pink stuff" available, the cheaper ethanol (alcohol) based version and the better propylene glycol based version. The two types are explained
here. Propylene glycol is not toxic and should not be confused with automotive antifreeze.
The good RV stuff (propylene glycol based) can cost a little more but for the jug or two you need, it's insignificant. It can be harder to find because most vendors stock their shelves with the cheaper product. I found a great price at a local independent RV repair & parts shop last fall and bought enough for 3 or 4 seasons. You also need to read the fine print on a label as it's not immediately obvious which type it is.
If you want to get rid of the odor, lubricate seals and not have to worry about flammability, use the
good pink stuff.
