What is the American version of Sugar Soap and "Biological washing powders?

Question:the BBC show " How Clean Is Your House" uses these products.

Answers:
Sugar soap is similar to TSP (trisodium phosphate) which is used to wash walls in prep for painting. You can buy TSP at DIY stores in powder or liquid. Sugar soap is sodium carbonate or sodium phosphate. Biological washing powders have enzymes added to "eat" the dirt. I don't know if we have bio washing powders in America; I've only seen them in the UK. I love watching "How Clean is your House" too!
