People with backne that's solved the problem, how did you do it?

Acne on my face was easy to get rid of, 1) I stopped washing it, and 2) I don't intake chocolate or anything like soda and sweets. My back though is another story. The only thing that clears me up is being out in the sun with my shirt off in the summer. Should I buy a back scrubber, or is there some sort of remedy soap or lotion that works? Note: salicylic acid and benzoyl peroxide products just make it worse.
