We used it twice and the amount of sludge that came out from the cleaning was nasty but has allowed my machine work better.

Why not just a cup of vinegar?

A cup of vinegar on the top rack is the standard advice, and it barely reaches the filter and spray arms where the grease and food actually collect. Vinegar is a weak acid that gets diluted the second the cycle fills with water, and running it regularly can wear on the rubber seals and gaskets, which is exactly what leading appliance brands warn against. Renuv drops in the detergent tray and works through the pump, filter, and spray arms in one normal cycle, clearing the gunk and scale and rinsing clean.

Your dishwasher smells, and it's coating your clean dishes
The problem

Your dishwasher smells, and it's coating your clean dishes

A dishwasher washes dishes but never washes itself. Grease, food bits, and hard water scale collect in the filter, the spray arms, and the seal around the door. That buildup is what makes the dishwasher smell, leaves film and spots on your glasses, and slowly chokes the spray jets so nothing comes out as clean as it should.

How it works

Three steps to a clean machine

Empty the dishwasher
1

Empty the dishwasher

Run it empty. The tablet cleans the machine, not a load of dishes.
