Query: Unfortunately didn't work

I love most of the Seventh Generation products but unfortunately this did not work very well for us. Left a lot of food on dishes and we had to basically either wash the dishes before putting into dishwasher or run the dishwasher again. Defeats the purpose. I'll keep checking back, hopefully Seventh Generation will be able to improve on this. Scent was great however, not too overpowering.
