Should dishes be rinsed in hot or cold water?


Many people have debated the age-old question of whether dishes should be rinsed in hot or cold water. Interestingly, there are compelling arguments to be made for both sides of this debate. On one hand, supporters of hot water argue that the high temperature helps to kill bacteria and ensures a more thorough cleaning process. This viewpoint is particularly popular among those who prioritize hygiene and food safety above all else.

On the other hand, advocates for using cold water during dish rinsing emphasize the environmental benefits associated with this approach. They argue that using hot water unnecessarily consumes energy and contributes to greenhouse gas emissions. Additionally, they point out that modern dishwashing detergents are specifically formulated to effectively clean dishes even when used with cold water.

It’s important to note that various factors can influence whether hot or cold water should be used when rinsing dishes. For instance, if you’re dealing with oily or greasy dishes, hot water may indeed provide a more effective cleaning solution by dissolving grease particles more efficiently. However, in cases where the majority of your dishes are relatively clean and simply need a quick rinse after washing by hand or in a dishwasher, using cold water might make more sense in terms of energy conservation.

Hot Water Rinsingshould dishes be rinsed in hot or cold water?

Hot water, typically defined as water with a temperature between 120°F (49°C) and 140°F (60°C), has several

Advantages when it comes to rinsing dishes:

  1. Effective Grease Removal: Hot water can help dissolve and remove grease and oil from dishes more effectively than cold water. This is especially important when dealing with oily pans and pots.
  2. Germs and Bacteria: Hot water can kill bacteria and germs on the surface of dishes, making it a more hygienic choice. This is particularly crucial if you’re handling dishes that have come into contact with raw meat or other potentially harmful contaminants.
  3. Dishwasher Compatibility: If you use a dishwasher, hot water is essential for the detergent to work effectively. Most dishwashers require a minimum water temperature of 120°F (49°C) to ensure proper cleaning.

Downsides to using hot water for dish rinsing:

  1. Energy Consumption: Heating water consumes energy, and using hot water for rinsing can contribute to higher utility bills. This is a consideration for those aiming to reduce their environmental impact.
  2. Risk of Burns: Scalding hot water can cause burns and injury if not handled with caution, particularly when washing dishes by hand. The high temperature can potentially warp or crack certain materials, such as fine China or glass. It is important to be mindful of the fragility of your dishes when deciding whether to use hot water for rinsing.

Cold Water Rinsingshould dishes be rinsed in hot or cold water?

Cold water, which is typically around 68°F (20°C) or lower, is the more energy-efficient option for rinsing dishes.

Advantages of using cold water:

  1. Energy Savings: Rinsing dishes with cold water consumes less energy since you don’t need to heat them. This can be a more environmentally friendly choice and can also lower your utility bills.
  2. Safety: Cold water eliminates the risk of burns associated with hot water. It is safer, especially if you have young children helping with the dishes.

Drawbacks to using cold water:should dishes be rinsed in hot or cold water?

  1. Less Effective Grease Removal: Cold water is less efficient at breaking down and removing grease and oils from dishes. You may need to use more soap and put in extra effort to achieve the same level of cleanliness.
  2. Limited Germ Removal: Cold water is less effective at killing bacteria and germs on dishes. This can be a concern if you’re dealing with items that have been in contact with potentially harmful substances.


Whether dishes should be rinsed in hot or cold water depends on various factors. Hot water can help to remove grease and grime more effectively, while cold water may be sufficient for lightly soiled dishes. Additionally, hot water can also help to eliminate bacteria and sanitize the dishes. However, it is important to consider energy consumption as well. Using hot water regularly can lead to increased energy usage and higher utility bills. Ultimately, the decision between hot or cold water should be based on the level of dirtiness and personal preference. Experimenting with both options can help individuals determine which method works best for them.
