You laugh, but my previous washer didn't rinse all the detergent out normally and I had to run every single batch a second time with no detergent added to keep my skin from getting puffy, usually in the most inconvenient places.

Only now, with my new washer that lets me do 2–3 "extra" rinse cycles, do I not have to age my clothes twice as fast with duplicated washing.

If the laws/regulations prohibit making washing machines that properly clean and rinse clothes, then the laws/regulations should be repealed.

It is possible that machine was restricting the amount of water artificially, to comply with better standards. I did an experiment with mine - you need to time when washing cycle ends and before rinsing starts, and then top up the water inside through the detergent compartment, all 1-2 liters in total. It indeed improves rinsing, but is very annoying to do in practice (hard to time correctly), so I stopped after a few tries.

Maybe you were using too much detergent? People have a tendency to use way more than is actually needed.
