IPA & Water Mix ratio

[KiwiTrev]

Looking to take advice with my window cleaning

It has been suggested starting with an IPA & water mix.

What ratio would be beat to adopt?

Straight denatured alcohol would work even better. Just sayin.

IMHO.... IPA is a good basic cleaner for relatively clean windows. For anything caked on the glass IPA wouldn't do the job. That said, start off with a 1:1 ration with either 70% of 90% IPA and move up or down from there based on preference.
