Here's a tip to check the safety of your filter: if you can run water over it and the water beads up rather than passing through, that's a sign that it needs to be thoroughly cleaned. It's not all bad news, though: the solution is incredibly simple.

To make sure your lint trap is effective, safe, and really clean, keep reading.

1. Remove the lint often. Ideally, clean it every time you run the dryer. If you make it part of your laundry habit, it will become automatic and you won't even have to think about it anymore.

2. Test for build-up once a month. Run the water over the filter about once a month (or more often if you do a lot of laundry!) and clean it when the water beads more than it passes through.

3. Run the filter through the dishwasher. That's right! Leslie says the hot soap and water from the dishwasher melts the buildup and makes the filter like new again.

4. Let dry completely before replacing. Setting it out to air dry is your best bet.

Keeping the lint filter really clean only takes a few extra steps, and it can make your home a little safer.
