It reliably removes grease and limescale film from the tub, spray arms and lines in a single hot empty cycle.

Its citric-acid formula targets the mineral scale and cloudy residue left by hard water.

Not for: Soft-water homes where grease, not scale, is the issue.

Affresh Dishwasher Cleaner (line)

Pre-dosed tablets drop into the detergent cup, so there is nothing to measure or spill.

Not for: Anyone who wants to treat heavy buildup in one pass, since tablets are made for routine maintenance.

Acid-based descaling: Look for citric acid or a similar acidic active ingredient if you have hard water. Mineral scale dissolves in acid, not in detergent.
Clean the filter first: Remove and rinse the filter before running any cleaner. A clogged filter is the most common cause of odor and poor washing, and no cleaner reaches packed debris.
Empty, hottest cycle: Run the cleaner in an empty machine on the hottest or sanitize setting. Heat activates the formula, and dishes block contact with interior surfaces.
Frequency: Roughly monthly, or more often with hard water. Buildup returns gradually, so occasional deep cleans let film and odor accumulate.

Running bleach and an acidic cleaner together.
Using a cleaner in place of rinse aid, since cleaners do not prevent spotting on dishes.

Vinegar can loosen light scale, but dedicated cleaners are formulated for the dishwasher cycle and handle grease and heavier scale more effectively.
