They don't here
Powder is the main detergent of choice.
I believe liquid became the dominant form of detergent in the U.S. because it dissolves quicker in a top loader and gets dispersed through the load faster.
The reason it is so bad is that it dosen't contain oxi-bleach, niether do colour friendly detergents. I *think* it may even be the case that a lot of U.S. powdered detergents lack it as well, unless specifically stated (Tide with Bleach)
I say liquids because it's easier than writing down all the non oxi bleach containing detergents. Should have been more specific i guess.
These detergents are fine to use on coloured clothes and delicates, but whites and clothes that need more sanitation need oxi-bleach, as does the machine to prevent gunk and mould and such.
Ofcourse the other popular alternative in the U.S. is chlorine, but front loaders are not designed for the use of chlorine, as it is rarely used in laundering clothes in Europe, and if it is then certainly not in the machine, and it can damage them over time.
So using one of these detergents and then adding oxi-bleach on white and light coloured loads, as well as towels and cloths and heavily soiled coloureds has the same effect, but, over here at least, it is far cheaper to just buy a powdered detergent containing it, and a seperate detergent suitable for coloureds.
Another point I've found is that out of the detergents suitable for colours, the powdered varities leave clothes cleaner and fresher than even the best liquids, yet still don't fade colours. For this reason, I dislike liquids in any circumstance.
