Product review (5 stars): Really stinky, easy to apply and works good! :)
When your racks are rusty, it stains the edge of your dishes.  This product does cover the rust!

Our old matag is 20+ years old. Still cleans good. We don't want to replace something that still works good. Replacing the racks would almost cost as much as a new dishwasher on sale. Catch 22.

This product was fast and easy to apply. It seems to be holding up well too.  Sure looks better and keep my dishes edges looking clean.  But, it's really stinky for a few hours and needs ventilation. Well worth it!
