I bought this dishwasher detergent that has 8.7% of Phosphates in it.It is considered commercial detergent to get through that loop hole but formulated for household dishwashers and there lower temps.This stuff works great like the old Cascade complete before they went to crap.I got 5 4 pound bags for 48 bucks and that included shipping ,that is 20 pounds of detergent which is not bad at all.Here is the Website link .Cascade commercial detergent is 60 to 80 bucks and you get one box that is 85 o.z. try this stuff it works great.I have tried to mixing phosphates with every brand and can never get them right but this stuff works..
