" The presence of suds doesn't present a problem in some machines"
Now that's where rubber meets road between vintage and modern dishwashers vis-a-vis detergents.
One has to dose modern automatic dishwashing detergents carefully in GE Mobile Maid or there's too much froth which she does not like. In fact even using a whole DW tab usually requires adding some sort of anti-foam (I keep type of silicone on hand for just those sort of occasions) agent.
Now one would think since GE Mobile Maid uses copious amounts of water compared to modern machines dosage of product wouldn't be an issue. Fact that it often can be so tells me automatic DW detergents around when these machines first hit market must have been formulated differently.
Have several canisters of Ecolab "metal safe" DW detergent. Stuff is largely sodium metasilicate, sodium carbonate with bit of surfactants. Makes nearly nil suds but will dissolve oils, soils and muck like nobody's business.
Have used it to soak broiler or roasting pans full of worse heavy oil, grease, food, etc... and it never fails to work a treat.
Here is P&G's patent application for DW detergent from 1987.

Oldest formula for Cascade can find online is for "with Sheeting Action" from 1996. It is a remarkably simple formula.
