How to get water stains out of clothes after washing and drying?

Some clear spots appear on my clothes after they’ve been through the washer and dryer. I don’t use any detergent or spot remover. I usually wash all laundry on cold or warm, rarely hot.
It’s a mystery to me why these spots appear.

Clothes aren’t stained when they go in the wash. Anyone else get these weird spots? How do I get rid of them?
