Query: Didn't Really Change Anything

When my dishes started looking filmy I looked into it and found about about the phosphate ban. Bought TSP and gave it a try. At first it looked like there was a small improvement. Over time though (even with continued use and changing up the amounts) things went back to normal. The only thing that worked for me was adding Lemishine (pretty much just citric acid I believe) to my detergent. After the first wash the dishes that had built up the film were noticeably cleaner. With the second wash they looked brand new. I'll probably look into finding just the ingredients of this product cheaper since I'll be using a lot but I think I'll add TSP every once in a while just to be safe.
