1. You forget about zipping before washing!
You probably never paid attention to your zippers when you washed your jeans or jackets. Well, next time you do your laundry, be mindful that all the zippers, no matter if they are made of plastic or metal, have rough teeth that can wreak havoc on both other clothes and the drum of the washing machine. They can also break it because of higher temperatures, so in order to avoid this, make sure you zip up any garments that have zippers before throwing them in the appliance. And if the material is too delicate, wash it by hand for safety’s sake.
