Questions about InLine Isopropanol

There are 400 ml in mine.

the best thing to do is to ask for isopropanol in a drugstore/pharmacy, high-percentage (>70%) even cleans the paint off, depending on the coating and time - the best thing to do is to try it out briefly and dilute it with a little water if necessary - but I've never had any problems with keyboards. ps: to avoid stains on delicate surfaces, do not spray directly but use a cloth/brush/flat stick/etc & do not use on steel/iron.

Hello I assume yes as it is pressurized bottle no change opened or unopened I know isopropyl alcohol is absorbing water over time so it may decrease in quality on long times Anyway i just bought so cannot witness on that Hope this helps
