Ever find those little silica gel packets inside the packaging of products you buy? They are there to absorb moisture to help keep products like knives, electronics and other goods dry. Instead of tossing them into the trash, save them: They can be used to dry up personal handheld electronics like smartphones and tablets. If your phone gets wet, just wipe off the excess water and place the phone in a mound of silica gel packets overnight. The packets will absorb the moisture and possibly rescue your phone from disrepair.
