Why 70% Ethanol only? | Hindi | Dr. Priyank Singhvi

In laboratory, you must have used 70% ethanol for sterilization. In hand sanitizers also, this is used quite frequently. But what is the reason due to which only 70% ethanol is used, but not 100% ethanol or, let's say, 40% ethanol? Why ethanol only, and not methanol? Let's understand through this video.
You can buy alcohol from here:
Generic Ethyl Alcohol aka Ethanol, Absolute: amzn.to/3vVgSfI
ISO PROPYL ALCOHOL 99% Pure: amzn.to/31c77LY
