For those tired of shelling out $8 for a little bottle of 'humidifier solution', you can easily and cheaply make your own. You can buy the Propylene Glycol from a number of sources, but I have included a link to the Chemical Store. All you then need is a small dispenser bottle and a quantity of distilled water (available at the grocery store) equal to the amount of P.G. you buy. When you get ready to mix (assuming 1 gallon size P.G.), simply pour half the water (two quarts) into a separate clean container. Fill the water jug back up with the P.G., then pour the remaining water from the separate container into the P.G. jug. You now have two gallons of solution at roughly 50%. Cap and shake. Now make some big labels to identify the contents of the jugs. Fill up your dispenser (preferably an empty one from a previous solution purchase) and go tend to your humidification devices. The price just went from $1/oz to $0.10/oz.
