Review on Effective Septic System Digester for Home Use - Prevent Sewage Back-Ups, Clogs & Odors - 4 Monthly Treatments, 32oz by Stacey Littlejohn

We have been very happy with the results of using the stain remover in the past but this new version does not seem to be as effective, particularly on red wine stains, as the old formula. I'm disappointed. Previously, the spots were weathered almost immediately. It remains to be seen whether yesterday's wine stain will come off the tablecloth. I bought a quart size based on the product's past performance and am wondering if I wasted my eighteen dollars. A piece of advice: if you have a product that does what you say it does, don't change it!
