"How to Mix IPA for Inspecting Correction Results
Here are the easiest ways to mix an approximate 10% solution for the most popular concentrations of Isopropyl Alcohol available at the retail level.
91% IPA
To mix a 32 ounce Spray Bottle
Pour 4 ounces or ? of a 16 ounce bottle of 91% IPA into a 32 ounce spray bottle and top the rest of the bottle off with water. This will make 32 ounces at 11.375% IPA to Water solution.
70% IPA
To mix a 32 ounce Spray Bottle
8 ounces (or ? of a 16 ounce bottle) will make 32 ounce of 17.5% IPA to Water solution. Get a 32 ounce container, pour in 8 ounces, (or ? of a 16 ounce bottle) of the 70% IPA and then fill the rest of the container up with water and you get 32 ounces of 17.5% IPA to Water solution.
50% IPA
To mix a 32 ounce Spray Bottle
8 ounces, (or ? of a 16 ounce bottle) will make 32 ounces of 12.5% IPA to Water solution. Get a 32 ounce container and pour in 8 ounces, (or ? of a 16 ounce bottle) of the 50% IPA then fill the container up with water and you get 32 ounces of 12.5% solution.
Why dilute concentrated IPA to an approximate 10% IPA to Water Solution
The most common dilution levels you can purchase over the counter are 70% and 91% Isopropyl Alcohol, sometimes you can find 50% version. At the time I'm writing this article, there are no other articles on this topic to give people a general guideline as to how to dilute and use Isopropyl Alcohol to chemically strip paint. I actually made a post to an AG forum thread where I encouraged someone else to write this article, but to date there's been no takers, so here's my offering.
Most of what I've read are forum members recommending one of two options,
Dilute IPA by 50% with water or 1:1
Use it straight out of the bottle
Most recommendations I?ve read are:
Dilute IPA by 50% with water or 1:1
Diluting 91% IPA 1:1 or by 50% with water would give you approximately a 45% dilution of IPA to water solution.
Diluting 70% IPA 1:1 or by 50% with water would give you approximately a 35% dilution of IPA to water solution.
Diluting 50% IPA 1:1 or by 50% with water would give you approximately a 25% dilution of IPA to water solution."
