For example, vinegar does a decent job removing dust and water spots, but it doesn’t cut through a lot of sticky stuff, and it tends to streak more than other cleaners. Rubbing alcohol is a potent cleaner but it’s harsh and strong-smelling so it’s not a great glass cleaner by itself.

That way the rice can absorb any leftover moisture from the phone a little more effectively. Isopropyl alcohol should dry relatively quickly but for good measure you may want to let your phone dry for a good 24 hours or at the very least let it sit and dry over night.

According to the National Capital Poison Center, rubbing alcohol, even in small amounts, is toxic when ingested. Like any other cleaning supply, keep your alcohol out of reach of children, and never put rubbing alcohol in a glass or another container, since it can easily be mistaken for water.

Rubbing alcohol is also highly flammable, so never use it near an open flame or high heat.

TO MAKE A STANDARD SOLUTION (70%): Dilute by adding 1 part water to 2 parts of this 99% Isopropyl Alcohol.

It is easily synthesized from the reaction of propylene with sulfuric acid, followed by hydrolysis. In some cases the hydration of propylene is carried out in one step, using water and a catalyst at high pressure. Isopropyl alcohol is mixed with water for use as a rubbing-alcohol antiseptic.

How to make hand sanitizer:

1. ⅔ cup of rubbing alcohol.
2. ⅓ cup of aloe vera.
3. 5 -10 drops of essential oil (optional)

The general use of non-alcohol-based hand sanitizers is not recommended. Alcohol-based versions typically contain some combination of isopropyl alcohol, ethanol (ethyl alcohol), or n-propanol, with versions containing 60% to 95% alcohol the most effective. Care should be taken as they are flammable.

“Isopropyl alcohol 70 percent, or isopropyl alcohol 99 percent diluted to 70 percent with purified water, kills organisms by denaturing their proteins. A 70 percent isopropyl alcohol solution dissolves their lipids and is effective against most bacteria and fungi and many viruses.”

A 70% concentration of ethanol or isopropyl alcohol has been demonstrated to be the most effective. Water acts as a catalyst and plays a key role in denaturing the proteins of vegetative cell membranes. The water content slows evaporation, therefore increasing surface contact time and enhancing effectiveness.
