What’s the best way to clean a red and white baseball cap?

My husband has a favorite baseball cap that he got a long time ago. It’s white with red lettering and red under the brim. He plays softball, and all the dust from the field has gotten it so dirty that he won’t wear it again until it’s clean. What would be the best way to clean it?
I’ve heard you can put a baseball cap in the dishwasher, but I’m worried that the red will bleed onto the white if I do that.
What kind of soap should I use?

try hand scrubbing it with cold water as to prevent the dye from leaching from the red to the white.
