cartridge cleaner clarification

[Westovers]

Your directions state:

For all spa cartridges and elements used in swimming pools where perspiration, suntan lotions, and other oils are present, soak the element for at least one hour (overnight is most effective) in (1) a commercial filter cleaner; or (2) one cup trisodium phosphate (TSP) to five gallons water; or (3) one cup dishwasher detergent to five gallons of water.

Are the measurements for TSP and/or dishwasher detergent for solid (powder) or liquid? I can not find TSP liquid--everything is called TSP "substitute" now. Are these substitutes OK for cartridges?

It's for powdered. TSP is found in the paint dept at HD or Lowes or the local hardware store. The powdered detergent is in the supermarket.

Typically use 1 cup per 5 gallons.

Will grocery store variety "dishwashing liquid" accomplish the equivalent? (Still 1 cup per 5 gallons?)

I have used Cascade with some success. Did that because I couldn't find TSP but this was because I was looking in the wrong place. I did find it at Home Depot in the painting section. It is a powder and comes in boxes. It may be worth noting that TSP seems to be regulated in certain areas and therefore, may not be able to be had in every painting supply store. The painting supply store folks would surely know the answer to this specific to their locale.

Store brand powdered dishwasher detergent works as well as expensive brands for this purpose. The purpose is to loosen dirt and degrease the elements. Works, is cheap, so I don't try to re-invent the wheel.
