I have used your dishwashing detergent for over 30 years, in fact it is the only one I bought. Over the last few years I have grown more disappointed with the product. It no longer suds up and does not last as long as it once did. Yes my water is the same as we have lived in the same area for over 27 years. My kids convinced me to buy Dawn and I find it to be a superior product. Have you changed your detergent in the last few years, if so are you going to change back. If there is not going to be a change for the positive I ,will have to switch brands. I find this very disappointing as I have used your product for so many years.
