You should never store important documents in the dishwasher during a hurricane — here's what to do instead

• It's a misconception to store important documents and other valuables in the dishwasher.
• Dishwashers are not entirely waterproof and should not be used to store important items in case of flooding.

As Hurricane Ian batters Florida's west coast, residents in the path should have their homes prepped for wind, rain, and flooding.

But there's a misconception that people in the path of the storm should store their important documents (marriage licenses, insurance policies, family photos, contracts, etc.) in the dishwasher because those are supposedly waterproof.

This is a bad idea. Do not use your dishwasher (or washing machine) to store valuables. Although these appliances are water-tight, they will not necessarily keep things dry in case of flooding. And in cases of severe damage, a dishwasher could get opened or destroyed during a storm.

"Appliances are not waterproof nor would we endorse such a tip," Kim Freedman, a representative for Haier-owned GE Appliances, told INSIDER.

Instead, store all important documents on a flash drive. If you are choosing to evacuate, all necessary forms of identification and paperwork should go with you. But it's always better to be safe than sorry. Scan any important papers and store them on a flash drive so you won't come up short if your home is flooded.

There's also a good use for your household appliances during a hurricane or threatened disaster — use your washing machine as a makeshift cooler. You may be filling up your fridge and freezer with ice to keep your food safe, but your washing machine (probably) can store a lot more. Fill the drum of your washing machine up with fresh ice to keep food cold, and to use as safe drinking water if the electricity goes out.

Another smart tip for anyone in affected zones: put a quarter on top of a frozen cup of water. The trick can help you determine if your food has been spoiled. Read more about how it works here.
