    You can make your own 90%+ isopropyl if 70% is all that’s available. The stronger stuff is better for many/most home cleaning and science projects.

    Put your 70% in a jar, add a shitload of salt, give it a shake. Siphon the alcohol off the top. There’s a clear boundary layer so you can see what you’re doing. It’s pretty cool!

    Also, most desiccant beads are reusable. Notice the rare, colored bead mixed in there? Those are indicators of how wet the beads are. You can microwave a bowl and recharge them. I cut the tiny packs open and pour in them in a jar for later. Also, paper coffee filters are great for making your own, larger packs.

    In any case, open your electronics and pull the battery ASAP. And no, don’t try to put it back together any time soon unless you chase the water out with alcohol. Let that shit sit a day or two. One time I pulled an old school monitor out of the rainy trash. Let it sit 48-hours, worked fine.

      90% is better for fast drying but for cleaning, 70% is often much better. People forget just how good a solvent water is, and there are plenty of things that dissolve in water but not alcohol (as you’ve noted, salt is one).
