There was a M1P like that in a crash thread quite a while ago, maybe it was worse.
It had spent 3 days on a rocky beach after washing up following an ocean crash.
All water though contains salts / minerals of some form.
In the OPs video, they washed / rinsed it with "clean fresh water" and that was the first (actually third) obvious test flaw.
Distilled water must be used to rinse out the contaminated water.
(I wouldn't even bother with the ocean crash though, even if taken out within minutes.)
Spent some time in the Aegean sea, left like that to dry off without washing out and eventually became a lemon

Ok, well if you ever think of selling it, I'd be Interested. Now since I know people are probably wondering why, let me explain. I plan to do YouTube videos soon and I need display items so I'm buying broken irreparable tech to fill that gap.
well after two months of working on this lemon, i made some lemonade, it still has a lot of footage to offer ?
only the camera left to assemble and weare good to go

Lots of IPA (I mean liters), baking soda, brushes, ultrasonic bath, a microscope, some new parts (2 motors, gps flex cable, imu, esc board, camera flex cable) and a little bit of quarantine time
It seams solid for now, i have been through 10 battery cycles and everything runs as it should

The keys to reviving water damage to electronics are: quick response to removing all power, and quick response to cleaning. Almost all forms of water will have salt/minerals in it that will conduct electricity, and all electronics need is a small amount of voltage sent on a data pin of a chip and that chip will be fried, this is why quick removal of power is important. Next is cleaning. The biggest issue that I see on the video of it being cleaned is that I don't see how cleaning like that would be able to get in all of the locations. Many of the chips today, mainly things like storage chips, ram chips, and processors are ball grid arrays and don't have exposed pins on their solder connections. If water gets under those chips, a quick rinse with anything will not fully get under those items to clean out the water that can still have electrical properties or cause corrosion. That is partly the quick response to cleaning, and it needs to be a through cleaning, usually in things like IPA in an ultrasonic bath.
If it's possible to remove power and start a deep through cleaning of all the electronic parts, the chances of revival is high, provided that there wasn't any shorting of electronics prior to all power being removed. As long as that has happened, and the cleaning was enough to get into areas that can't be reached easily (such as under the BGA chips), then the likelihood of things failing later on are slimmer. The biggest issue is that is very very difficult if not impossible to make sure that every location that water can seep into is cleaned properly to prevent corrosion.
