I started using Finish non phosphate All-in-1 tabs in June, so they were out for sale then, at least in my area. I have a stash of phosphated detergent but I rotate DW detergents each week, so I switch between Finish non phosphate tabs, Finish non phosphate powder, Cascade Complete non phosphate powder,Cascade All-in 1-Gel non phosphate, Finish Quantum Tabs with phosphate, old Electrsol 3 in 1 tabs, and Miele DW powder. The Cascade powder does an OK job but is not as good as Finish. Cascade Gel works OK but has a strong scent. Last week I used Quantum tabs with phosphate, this week I am using Miele tabs with phosphate. Next week I will use Finish non phosphate powder. I Don't know how Cascade Action pacs peform. I tried them last year but the scent in them was so strong that I could smell it on the dishes after the cycle so I hesitate to try them again.
My box of Finish All-in-1 tabs non phosphate has a series of green colored squares on the back of the box. The squares are labeled "Our Home Our planet" and within one of these squares is the phrase "Phosphate Free!", written so small you would miss it if you aren't looking for it.
