kinda 'spensive, but if you use 'Dishwasher Magic', Finish Dishwasher Cleaner, or something similar, every month or so, your dishwasher ought to stay in pretty good shape... alternatively, if you run a cup of white vinegar thru once a week, or maybe use Affresh Dishwasher Cleaner tabs (cheaper per use than the other cleaners noted above) mixed in every few weeks instead of the vinegar, you can use the heavier duty stuff only three to four times a year. Assumes stainless steel tub, and that you manually wipe down seals after vinegar treatment, and runs about $30-$40 year.
