Why does dish soap go from cutting grease to just pushing it around?
I used the same bottle of lemon soap for 6 weeks and around week 4 it stopped cutting bacon grease and just smeared it across the pan. I think the grease builds up in the sponge and the soap can't cut through it anymore, but my roommate swears the soap itself gets weaker after it sits open. Is it the soap going bad or the sponge getting gross, because one of those is way cheaper to deal with.
