Attention all sleep-deprived, coffee-dependent, tumbler-toting moms . . . when’s the last time you washed that thing??

According to this viral Facebook post, people aren’t cleaning the lids on their Yeti (and similar brand) cups correctly, and it could be causing some real issues. Veronica Lucas writes, “Apparently doctors have been finding that some patients are struggling to fight off unexplainable infections . . . even after multiple antibiotics!!!”

The apparent culprit? Mold lurking under the rubber seal on the lids of reusable drinkware.

Umm, gross!

It turns out that just running this type of lid through a cycle on the dishwasher isn’t enough. To get them squeaky clean (and prevent them from getting that nasty build-up), the removable rubber seal needs to be removed and washed separately.

Moms, we suggest penciling five minutes into your busy schedule to check out those lids before you, or your sweet little ones, go back to sipping on your favorite cup. It might seem like basic cleaning practice, but it’s easy to get so busy that a quick rinse sounds like enough—it’s not. So here’s your friendly reminder that ALL reusable drinkware with multiple parts should be completely disassembled and cleaned after every use.

Trust us, it’s worth it!
