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.
Step 2: Gather Supplies
1. Spray bottle
2. Tear-less baby shampoo (name-brand or generic)
3. Table spoon
That's it!!! No nasty vinegar smell!! Amazzzzazzing!
Step 3: Mix It Up!
1. Take 3 table spoons of the baby soap, add to bottle.
2. Fill with water
The bottle should have a slight gold coloration from the soap, but mostly clear. And will slightly bubble.
Step 4: Use It!
After all mixed up, use it. Only a couple sprays will work.
It will truly have a streak-free shine. I have used this on mirrors, electronics (no direct spray), sunglasses, etc.
The smell will smell like the best thing ever, babies! No urination smell from vinegar and ammonia.
