• Use a vacuum cleaner

If you want to try and suck the liquid out of the inner parts of the phone, try using a vacuum cleaner if there is one available. Remove all residual moisture by drawing it away with a vacuum cleaner held over the affected areas for up to 20 minutes, in each accessible area

• Use a substance with a high affinity for drawing out moisture

An inexpensive option is to place the phone in a bowl or bag of uncooked rice overnight or up to 48 hours. The rice might absorb some remaining moisture and act as an desiccant.
