Silica gel desiccant bags. That's the same thing used in a lot of packaging material, like the little thing that says "do not eat" in a pill bottle or electronics bag.

There is a small risk the rice will work and you won't buy a new iPhone. Do you want to break the economy??

This is actually a thing. Worked in Apple Stores for years and saw laptops and phones full of rice. Whole grains and bits n bobs.

So before the rice you could actually do a modular repair sometimes. Swap out the battery or SSD.

Whole thing full of rice bits attached to every component? Forget it.

Also, once a device is liquid damaged, often rice will resurrect it but only until the logic board rusts through / goes dry. Copper oxidises over time.

On the other hand, if you can’t afford a repair or swap out, (contrary to popular opinion, Apple sell replacement devices through their service channel way cheaper than new units) rice might give your device a new lease of life. So sometimes worth the gamble.

Edit: missed the D off SSD which kind of changed the context!
