So, I read one of the guides on how to repair an iPhone 6s that went through the wash, and it says I need to use 90% isopropyl alcohol to clean the circuit boards inside. Will 70% work, as that is what most people will have for medical reasons? Thanks.
Is this a good question?

If your iPhone went through a washing machine cycle I’m afraid whatever alcohol you may use it won’t make much difference; when a phone is submerged water gets literally anywhere and disposing of residues would need professional tools to remove metal shield protections and ultrasonic bath to start with. Battery and screen will have to be replaced for sure and further damages needing microsoldering skills can be easily expected. Unless you need to recover important data from your phone the advantages to attempt a repair vs buying a used 6s iphone, given current market prices, would be rather questionable.

I already replaced the screen and removed the battery, but I don't know what you mean by "metal shield protections." The guide I read iFixit said that I could use either the ultrasonic bath or the alcohol... I am not sure what to do. I can see no evidence of corrosion on the circuit boards I can see.
@ititanium Have a look at this teardown..iPhone 6s Teardown
At steps 18/19 you see how the logic board should be prepared to be properly decontaminated from residues. The metal EMI shields cover a big part of components and unless they're desoldered you wouldn't be able to decently clean your board.
Ok, thank you!

Use the 90% as the rest is water. I prefer methanol, which is pure with no water but harder to find.
