Silica-based cat litters and uncooked rice are two household items that you can use to dry out a laptop. Do bear in mind that drying with rice will take longer than with cat litter. Either way, it’s also best to leave your laptop to drip dry first to remove excess liquid. Place the laptop in a large sealable plastic bag or container and top it up with rice or cat litter. Then, leave it for 1-5 days, depending on the severity of the spill, check it daily, and take it out when you think it’s dry.
