isopropyl alcohol 90% replacement

isopropyl alcohol 90% replacement Replacing my Apple Watch S1 screen. In the replacement instructions there are a couple places that says to use isopropyl alcohol 90% or better. Due to Covid-19 all the stores in my area don’t have any at this time. Is there a substitute I can use?

"This might be a good time to mention that for electronics 99% isopropyl alcohol is safest and

for disinfectant 70% is most effective.

This web, though commercial, describes all the concentations and why best quite well.
