Note that you won’t be able to do this with all fabrics. Leather, for instance, can’t be ironed. You should strongly consider storing such clothing to preserve signatures rather than wearing it.

Make sure there’s no steam coming from the iron. Water will prevent the ink from setting, and will actually help remove the signature. [2] X Research source

Be aware that not all types of clothing can be put in the dryer. For these, you should strongly consider storing them rather than wearing them if you want to preserve the signatures.

You can buy display cases specifically for holding autographed clothing or jerseys. These typically control the amount of light that enters the case, protecting the clothing within.

If storing your signed clothes in a drawer, note that they won’t last as long without proper airflow. The signature might also rub off on other clothes stored in the same drawer.
