Product review (5 stars): The old sprayarm washer looked fine, but was rough after 9 years of use
Really made a difference when arm was not turning well.  The old sprayarm washer looked fine, but was rough after 9 years of use.  After a struggle with some detergent and rinse aid that did not work well  (and I replaced and went with a detergent - biokleen powder - that worked very well)  this has finally helped my dishwasher work like new again.
