Anything Other Than RV Anti Freeze?

I have NEVER used that 'rv anti-freeze'

BUT I do use Olive Oil in toilet and a splash or two in 'p' traps

Olive Oil will turn slushy but not freeze, doesn't evaporate, keeps toilet bowl seal lubed/flexible

Thanks for the olive oil tip!!!

use a glycol based antifreeze (more expensive) instead of an alcohol based antifreeze.

I use olive oil for the toilet seal when winterizing. It's not petroleum based and works really well.
After winterizing the toilet by running antifreeze through it, I pour a little olive oil with a bit of antifreeze into the bowl and partly flush it leaving a half inch or so in the bowl.

It has always sealed.

Is the antifreeze evaporating? Or is the toilet bowl leaking down. I have never had antifreeze evaporate from the bowl over the winter. But I did have it leak down one year when my seal was leaking. I do use propylene glycol RV antifreeze.

Thank you Old-Biscuit! I posted that the other day and others seemed to think I was crazy. We put it in anytime the trailer is going to sit for awhile to keep seal lubricated.

What length of time can olive oil sit and not go bad?
I don't want mold or something growing.

I use silicone spray from a spray can. Lasts all winter and lubes the seal. The red straw keeps me from spraying all over and I stop spraying when the top of the seal is reached. I bet it is cheaper than that "extra virgin" stuff and never turns rancid.

FYI Ethylene glycol, used in radiators tastes sweet and is extremely toxic - dangerous to pets, kids, and wild animals. RV antifreeze contains propylene glycol which is nontoxic.

I never checked to see if it was still good after being in the toilet! :B

I have been using it for a number of years and have never noticed any mold. As I posted above, I mix it with a little antifreeze just to keep something in the bowl. There has always been some left in the bowl in their spring. Last winter it sat that way from October thru early May.
