I used to work for an import/export packaging place and the owner was a really into high-end electronics. He showed me a trick where you place a waste damaged device into a sealed bag with molecular sieve (kinda like silica but way better) and 24-48 hours later is dry inside and out. I do regular (every 6 months or so) drying maintenance on all my daily use electronics (phone, laptop, etc.) Plus I've fixed many friends phones and laptops using molecular sieve and a mylar zip seal bag. Putting electronics in the oven is risky biz. Rice sometimes works but actually can do more harm than good. Best alternative... through it in the vegetable crisper in your refrigerator. It usually is the least humid place, best for drying.
