How to Wash a Baseball Cap

Steps
Place the hat in the mold
Insert into the dishwasher with nothing else in it, other than another hat
Place normal dishwashing soap in the dishwasher like you normaly would.
Run it for a "Normal" cycle.

Tips
Don't use too much soap, for if you do, the hat can retain some of it. The worst part about that is when you get stuck in the rain for some reason with the hat on, and then you look like you just stepped out of a washing machine on the wash cycle.

Warnings
Do not do this with a wool hat! Wash in sink with cool water and mild detergent such as Woolite.
Don't do this too much to a hat as you'll weaken it's stitching, making it just disintegrate.
Only use liquid detergent on this!
Remember not to put it on "heat dry", this can ruin your hat.
