We're all making this mask-wearing mistake, according to Gov. Gavin Newsom's office

Just when you think you've got this mask wearing business down pat, Gov. Gavin Newsom hits you with a curveball.

The governor's office tweeted out a video PSA Tuesday with five common mask-wearing mistakes.

The first mistake highlighted is one that most people are probably making: touching the front of your mask or face covering.

Do your masks need a filter? And are you cleaning them the right way?

According to the PSA, doing so can contaminate the surface with your dirty hands. Adjusting the mask around your face can also let germs in.

Once you start paying attention, you may notice how often you breach this proper mask-wearing protocol.

Remember, wearing a mask in public places where you're unable to stay 6 feet away from others in California is required by law. Some cities like Beverly Hills have even stricter requirements and will issue hefty fines to those who do not comply.
