Cascade Complete "HydroClean" Gel, With Bleach
Love the stuff, though in general have found all the Cascade "Complete" or "Pure Rinse" versions give great results.
When Electrasol tabs first came out, gave them a try and results were ok, but when the rinse agent (little power ball) was added found it made too much suds. Indeed find most versions of Finish or Electrasol tabs made too much froth.
One could hear dishwasher pump and motor straining to move that froth around. Also found neither of the above tabs really did a good job on two or more day old (we don't run our machine daily, only when full), porridge bowls. We are big on flax seed meal, along with nuts and fruit in our pooridge, and am here to tell you the stuff dries on like Gorilla glue. With dishwasher detergents other than Cascade, found bits of flax seed meal all over dishes, and often bits of dried oats still on bowls. Not any more.
As for tabs, gelpacs and the like, really prefer gels or powders as one can control dosage to suit. Tabs can and will go hard if one stores them too long (know this because one nabbed tons of Electrasol tabs when they went on closeout a local shop, only to find later they turned into hockey pucks from being stored away for so long).
