Have a Hotpoint dishwasher from 1988. Still seems to run fine but does
a hit and miss job of cleaning. Leaves a noticeable film on glasses on
the top rack, is hit and miss on plates. Doesn't seem to matter what
detergent I use.

As far as I can tell there's still a strong jet of water getting
sprayed, gets plenty hot but it clearly seems to be less effective.
Any insights as to why this is?


In the past year or so, dishwasher detergent manufacturers, in obeisance to
the green gomers, stopped making detergent with phosphate. This condition
can be easily remedied by adding phosphates to your detergent (it's like
adding two fresh eggs to a cake mix).

Using a powdered detergent, empty the contents of the box into a large bowl.
Add 10-15% by weight or volume of tri-sodium phosphate*. Mix well. Put the
mixed powder back in the box**.

Your dishes and silverware will sparkle!

I have found that adding 1/4 cup of Borax will help the detergent clean
better and leave fewer spots on glasses.

And Borax doesn't put phosphates into the environment.
