Why Your Dishwasher Needs Regular Cleaning

A dishwasher cleans your dishes — but it cannot clean itself. Over time, grease, food debris, mineral deposits, and odor-causing bacteria build up inside the pump, tub, spray arms, and hoses. This buildup reduces cleaning performance, causes unpleasant odors, and shortens the lifespan of the machine. A monthly cleaning cycle with a dedicated dishwasher cleaner tablet removes this buildup and keeps the machine running at its best.

What Dishwasher Cleaner Tablets Do

• Remove grease and food residue from inside the pump, tub, and hoses
• Dissolve limescale and mineral deposits from the spray arms and interior surfaces
• Eliminate odor-causing bacteria that build up in hidden areas of the machine
• Restore cleaning performance that has declined due to internal buildup
• Protect the machine’s components from long-term mineral and grease damage

Best Overall: Affresh Dishwasher Cleaner Tablets

Affresh Dishwasher Cleaner Tablets are specifically engineered to power away odor-causing bacteria, limescale, and mineral deposits from inside the pump, tub, and hoses. Each pack contains six tablets — a six-month supply at the recommended monthly cleaning frequency. They are designed to be used in an empty dishwasher on a hot cycle, reaching areas that regular detergent never touches.

• Removes odor-causing bacteria, limescale, and mineral deposits
• Cleans inside the pump, tub, and hoses — not just the visible surfaces
• Six tablets per pack — six-month supply
• Easy to use — place in the bottom of an empty dishwasher and run a hot cycle
• Compatible with all standard dishwashers

How to Use a Dishwasher Cleaner Tablet

1. Remove all dishes from the dishwasher — run the cleaning cycle on an empty machine
2. Place one tablet in the bottom of the dishwasher tub — do not put it in the detergent dispenser
3. Run the hottest, longest cycle available — most dishwashers have a heavy or sanitize cycle that works well
4. When the cycle finishes, leave the door open for 15 to 20 minutes to allow steam to escape and the interior to air dry
5. Wipe down the door seal and edges with a damp cloth to remove any remaining residue

How Often to Use a Dishwasher Cleaner Tablet

• Standard use: Once a month is the recommended frequency for most households
• Heavy use or hard water: Every two to three weeks if you run the dishwasher daily or have very hard water
• Infrequent use: Every six to eight weeks if you run the dishwasher only a few times per week

Signs Your Dishwasher Needs Cleaning

• Unpleasant odor coming from the dishwasher
• Dishes coming out with grit or residue despite correct loading
• Visible grease or film on the interior walls or door seal
• Reduced cleaning performance that cannot be explained by loading or detergent issues
• White or gray mineral buildup on the spray arms or interior surfaces

Cleaning the Filter Too

A dishwasher cleaner tablet cleans the internal components — but it does not replace manual filter cleaning. Remove and rinse the filter every two to four weeks alongside your monthly cleaning cycle for the best overall maintenance routine.

Final Tips

• Run the cleaning cycle on an empty dishwasher — never with dishes inside
• Use the hottest cycle available for maximum effectiveness
• Clean monthly — do not wait until you notice odors or performance issues
• Clean the filter manually every two to four weeks in addition to the tablet cleaning cycle
