The how and why behind the magic:
Isopropyl is hydrophobic (it pushes water away from itself; literal translation being “water-fearing”). When you put your wet phone into a bowl full of 99% isopropyl, the isopropyl pushes the water away from the phone’s sensitive electronics without damaging the phone. The percentage on the bottle indicates how much isopropyl to water content is in the bottle. For example, 99% on the bottle means 99% isopropyl and 1% water, 70% means 70% isopropyl and 30% water (this is the reason we want 99% and not lower). Using isopropyl is also the preferred method in my opinion because it helps to remove a larger possibility of corrosion formation from any water molecules left behind when using a silica/rice method. The silica/rice method helps to remove the moisture, but with a 99% isopropyl bath, you can be pretty sure you aren’t leaving any water behind.
The silica packets and rice methods rely on the desiccant properties of the materials (a desiccant literally sucks the moisture out of it’s surrounding environment). Everyone has heard of putting your soggy phone in a bowl of uncooked rice, but I would recommend the Gazelle study that disproves this popular notion (Gazelle is a large electronics buyer of second-hand and used devices). To sum it up, uncooked white rice was actually worse than leaving the phone to air dry, but silica packets still reign supreme as thee drying agent. iPhones performed worse than their Galaxy compatriots in revivals (mostly due to the irremovable batteries). Couscous and instant rice also performed better than uncooked white rice. “However, this does not prove that the drying agents are incapable of outperforming open air under the right circumstances”, this quote is important to keep in mind when reviewing their findings.
So, if you do decide on the silica gel packets/rice method, go with the packets whenever you can.
