Follow the washing instructions.

Every binder has a tag with the washing instructions on it. Did you lose it? No Worries! This is what it looks like:

We recommend drying it laying flat because this is the best way to keep it from shrinking, or loosening. The most effective way to do it is to lay it flat on top of a drying rack.

The binder seems loose.

Often this means it's time to wash it. If it has been soaking up a lot of sweat, or you have waited too long to wash it, it might need another rinse with cold water and to be dried laying flat. But it should go back to its original shape.

Use the right amount of laundry detergent.

Most people use too much detergent, and it's bad for your clothes. Check how much you should use for the amount of laundry you're washing. You will be able to enjoy all your clothes for much longer, not just your binder.
