The regulations on the wash cycles, including water volume, time, energy, and detergents, are very restrictive. Older units were not subject to the same regulations.

For example, due to laws in California most commercial dish detergents won’t contain TSP (trisodium phosphate). I’ve been adding a bit of powdered TSP with the detergent pod to each load and it seems to have improved the results.

So fuck the environment, the rules are for other people?

It seems like you’re implying that laws in California apply also to people who live in other states?

Indirectly, they do. Same thing as ES rules. The EU rules do not apply to the US, but by virtue of being a huge market, products are designed to follow those requirements. And companies will want to avoid creating entirely different product lines for different markets - so at least some of those rules and restrictions will end up in those products.

I believe detergents never used TSP to begin with; they used another more unstable posphate which worked better.
