Why You Need a Dishwasher Cleaner
Does your dishwasher smell bad or leave residue on dishes? This is usually caused by grease, food particles, and mineral buildup inside the machine. Regular dish detergent cleans plates, but it doesn’t clean the dishwasher itself.
A dedicated dishwasher cleaner helps by:
- Removing grease and food residue from hidden areas
- Breaking down limescale and hard water deposits
- Eliminating unpleasant odors
- Maintaining strong cleaning performance over time
Using a cleaner regularly can also extend the lifespan of your dishwasher.
How Dishwasher Cleaners Work
Dishwasher cleaners are designed to clean the internal components you can’t easily reach. Most products fall into three main categories:
- Tablets or pods: Dissolve during a hot cycle and clean spray arms, filters, and interior walls. Best for routine maintenance.
- Liquids: Flow through jets and drains, making them ideal for deep cleaning and heavy buildup.
- Powders or crystals: Often citric acid–based and especially effective for hard water scale and mineral deposits.
Choosing the right type depends on your water hardness and how dirty your dishwasher is.
