How to clean/disinfect my grandpa's cap.
My grandpa recently passed away and wore ball caps pretty much exclusively. I acquired one of his caps that he wore a ton as a work outside cap. I want to wear it to keep his memory alive but I don't know how to clean it. I love my grandpa to death, but I don't want to sweat in a hat he profusely sweated in lol. How can I clean it and make it sanitary enough for me to use without further wear and tear?
