Finish Dishwasher Cleaner Liquid.
About This Product
Finish dishwasher-cleaning liquid in a 4-bottle pack — about a year's supply at one bottle every three months. Each bottle is one cleaning cycle: run it in an empty machine and its dual-action formula clears grease and limescale from hidden parts like the filter, spray arms, and pipes.
When It Helps
- Cloudy glasses or filmy dishes
- Lingering odor from the machine
- Hard-water scale inside the tub
- Buildup in hidden parts like the filter
- Quarterly dishwasher upkeep
How to Use
- Empty the dishwasher completely.
- Remove the sticker to expose the wax plug (leave the cap on) and place the bottle upside down in the bottom rack.
- Run a hot cycle with no dishes and no detergent. Discard the empty bottle after — use one about every three months.
Why Korean Customers Reach for This
As dishwashers become standard in Korean kitchens, the machine itself needs care the dishes don't — the filter, spray arms, and pipes collect grease and hard-water scale over time. Running one bottle through an empty cycle every few months keeps glasses clear and the interior fresh, and the 4-pack covers about a year.
