I have used of ton of commercial bought glass cleaners for home and auto. And they all leave either the nasty ammonia smell or had streaks. I have seen the homemade glass cleaners, but vinegar( to me) smells nasty. But then all was changed when I found out about the baby Shampoo glass cleaner.

Step 1: The Science

Tearless Baby Shampoo has a measurement of 5.5 on the pH scale. Which makes it a safe solution. If your baby decides to lick the window, you will be comforted to know that he or she should be safe unless of an allergy or freaky uncontrollable element.

We all know that pH 'potential Hydrogen" is the measurement of a solution/substance to be acidic or alkaline (base). The scale goes from 1-14. So less than 7 is to be on the acid side and greater than 7 is to be alkaline. 7 is neutral, and what substance is that, pure water.

Common things that are acidic (less than 7); Lemon Juice 2.5, Vinegar 2.4-3, Tomatoes 4.3, Coffee 5, Clean Rain 5.8

Common things that are alkaline (more than 7); Tears 7.4 Sea Water 8, Baking Soda 8.5, Milk of Magnesia 10.5 , Ammonia 11, Bleach 12.5

When pH drops below about 2.5 or goes above 10 it is considered potentially hazardous. So think of it as you don't want to put lemon juice in your eye. Milk of Magnesia is slightly higher because it is used to counteract the stomach acidity.

Think about this commercial window cleaners can be any where from 10-14 on the pH scale and don't really look like they clean good.

<p>Good post, nice to let people know about the pH scale as many people don't realize that vinegar is acidic and should never be used to clean mirrors or many other sensitive surfaces as from continuous use of vinegar will cause detrimental damage to surfaces, mirrors are just one example.</p>
<p>Thank you very much for your comment. I know lots of people that use it to disinfect (gross...) and they still get sick. I am bleach kind of guy, I want to make sure those nasty viruses and germs are D...E...A...D...DEAD. And good to know my house doesn't smell of that urine-clean smell. </p>
