I've been using distilled water for couple years now and I hate having to re-fill it every couple months or so. I know I'm supposed to use Propylene glycol, but when I ask for it walgreens or cvs they look at me like I'm growing horns out my head. Any ideas where I could find some, or a similar inert liquid (with a similar viscosity). Thanks for the help in advance.

Try mineral oil. Most grocery stores carry it.

 

[Jeff.:P:.]

Hmm, has anyone had issues with using Mineral oil?

I've aways just used regular water and fill it up about 3/4. It last pretty long and if your using a diffusor you can still tell if the bubble rate is the same even if it goes empty.

Ya that's what I've been doing more or less. I found that I could get glycerine in the Baking Isle of most grocery stores. I'm going try that and see if that works.
Thanks again for the help guys. Jeff.:.

I've been using glycerin for quite a while with no adverse affects.

 

[Jeff.:P:.]

Excellent, that's what I thought.

I tried the Glycerin and it would foam up if your bubbles are to large so i'm going to try Mineral oil witch is liter than Glycerin and heaver than water and it will not foam up?
