DW detergent is very caustic. As far as reducing the amount used, do some
trials. The type of water you have makes a difference. The more minerals,
the more detergent you need to achieve the same cleaning.

I use about 2/3 fill in the first wash, 1/2 in the second wash cup.

Years ago, liquid dish detergent (the in sink kind) used to be measured by
the capful. Then the maker came out with the squeeze bottle. It was a
bonanza for them. One squirt it good, but two must be better?
