The only things I have that need to be dry-cleaned are couple of jackets and a few pairs of dress slacks, which I only wear to job interviews, court appearances, weddings and funerals. The last time I had any of them cleaned was years ago.
(To be honest, I've never attended a funeral.)
BTW, trying to save a few bucks on dry cleaning by washing clothes at home with gasoline is extremely dangerous! (Really, did people actually do that?)
