You might feel a little silly doing it, but nothing, I mean nothing, works as well as hanging the pants on a car wash mat holder and spraying them with high pressure soap and water. It takes me less than a minute to do and I never have to pre-treat, scrub or soak. I have people ask me all the time how I keep the white baseball pants clean. I was spending $20 a month in products before someone taught me this quick trick at a tournament.
