Alcohol deemed effective for hand sanitizing.
The CDC and many other Government Agencies are recommending alcohol based hand sanitizers to prevent the spread of the Flu virus. Most hand sanitizers kill bacteria, but only concentrations of 60% or more alcohol kills viruses.
Anyone who has purchased these products(if you can even find them!) know they are expensive! Like many other products, most of the cost is for advertising, bottling and shipping.
Purell $4.49/8 ounces 56 cents/ounce
Germ-X $4.49/8 ounces 56 cents per ounce
Germ-X pocket size $2.29/2.5 ounces 91 cents per ounce
Since those extra costs are not going to get your hands cleaner--skip them and make your own Sanitizing Hand Cleaner--refill the old bottles and save some big bucks!
These products all have the base ingredient: denatured or "rubbing" alcohol. The formula for this type of alcohol is dictated by the Federal Government so every source of this type of alcohol is the same--buy the cheapest you can find!
So far, the cheapest source I have found for denatured alcohol is at the hardware store in the paint thinner department. My local Lowe's Hardware has it for $6.69 per quart or $15.28 per gallon and it is 90% alcohol(with exactly the same methanol and acetone added as you would find in the pharmacy as "rubbing alcohol" except that rubbing alcohol is typically 70% alcohol and has water added to bring it down to that concentration.

Household Bleach is the Best Virus Killer
Store-brand chlorine bleach can be used as a disinfectant by mixing 1/4-cup chlorine bleach with 1 gallon of cool water. --Ratio of 1:64 . Bleach has been found to be the best civilian sanitizer and is a very common base for antibiotic cleaners in Third World Countries because it is very, very cheap. To extrapolate this into a homemade hand sanitizer we can start with a bottle of inexpensive hand lotion and add bleach to it.
Bleach Based Hand Sanitizer
Dump the contents of a bottle of hand lotion into a mixing bowl, add bleach, mix well and return to the bottle. Be sure to mark the bottle "With Bleach Added: 1:64"
Bottle size --------- Amount of Bleach to Add
8 ounce --------------3/4 Teaspoon
16 ounce ------------1/4 ounce (1 1/2 Teaspoon)
32 ounce ------------1/2 ounce (1 Tablespoons)
Extra benefit: This small amount of bleach will leave your hands very clean and make your nails super white!
Some people are pretty allergic to chlorine bleach and they should go with the alcohol based sanitizer instead, but for sheer virus killing properties, bleach is always the best product for the job.
