The Better (Spray) Recipe
Isopropyl alcohol (also here)
Glycerol or glycerin
The aloe mixture gets the job done, but aloe also leaves your skin annoyingly sticky. So, here's a recipe that's less sticky and more potent, based on the mix recommended by the WHO.
Mix 12 fluid ounces of alcohol with 2 teaspoons of glycerol. You can buy jugs of glycerol online, and it's an important ingredient because it keeps the alcohol from drying out your hands. If you can't find glycerol, proceed with the rest of the recipe anyway and just remember to moisturize your hands after applying the sanitizer.
Mix in 1 tablespoon of hydrogen peroxide, then 3 fluid ounces of distilled or boiled (then cooled) water. (If you're working with a lower-concentration solution of rubbing alcohol, use far less water; remember, at least ¾ of your final mixture has to be alcohol.)
Load the solution into spray bottles—this isn't a gel, it's a spray. You can wet a paper towel with it as well and use that as a wipe.
If you must, you can add in a splash of essential oil to your concoction to make it smell nice. Just don’t use lavender. Everyone else uses lavender, and your sanitizer is superior.

I often use it for chigger bites, just splashed on my ankles and much less rarely use a little to 'wash' my hands. I don't have any reaction or sensitivities to it though and some folks might. It does not seem as drying to my skin as I thought it might be. I used to use it often as an underarm 'deodorant'.
If you are not looking for antibacterial though how about a jar with small squares of cloth covered in a lesser percentage of alcohol with some water? Pull out one at a time and hang to dry and wash them later. I've always intended to do something like that to keep in the car. A wide mouth quart would hold several.
