Can You Wash Dishes With Cold Water?

Most of us have heard that we can save energy by washing dishes with cold water. But does that actually make a difference? Is it really worth the extra effort?

You can wash dishes with cold water. Cold water might take longer to clean your dishes than hot water, but it is just as effective. To get rid of stubborn grime, you only need high-quality dish soap or a naturally occurring antibacterial agent like lemon, vinegar, or salt.

In this article, we will look at the pros and cons of washing dishes with cold water. We will explore the science behind it and the potential alternatives to dish soap. 

Can You Wash Dishes With Cold Water?

Yes, you can wash dishes with cold water. While hot water may be more effective at removing tough grease and food residue, cold water can still do the job. In fact, if you use a detergent specifically designed for cold water, you can get your dishes just as clean as you would with hot water. 

Cold water is also more environmentally friendly, as it requires less energy to heat up. Plus, it can help save money on your utility bills.

If you are using cold water, it’s also important to let the dishes soak for at least a few minutes before scrubbing. This will help loosen any hard-to-remove food particles and make your dishes easier to clean.

It’s important to keep in mind, however, that cold water may not be enough to kill certain bacteria, so it’s important to follow the instructions on your dish detergent and scrub vigorously to ensure your dishes are properly sanitized. 

All in all, cold water washing may take a little bit longer, but it’s perfectly safe to use for washing dishes. It’s both efficient and eco-friendly.

Does Cold Water Clean As Well as Hot Water?

In some cases, cold water can clean as well as hot water. However, hot water is more effective at killing germs. Cold water can effectively remove dirt, dust, and oils from surfaces. It’s also less likely to cause damage to delicate fabrics like silk or wool. 

Hot water reaches temperatures of up to 149°F (65°C), which, according to the World Health Organization, is enough to kill most germs. 

On the other hand, cold water is limited to a maximum of only around 68°F (20°C). As such, it won’t be as effective in killing germs. Cold water can be useful for some cleaning tasks, but hot water is still the best choice when it comes to cleaning organic residues.

Nonetheless, cold water is still effective at cleaning dishes, removing dirt, and getting rid of that greasy film.

The key to using cold water is to add a few drops of dish soap before you start. This will help break down the dirt and grease, allowing the cold water to do its job. And while the molecules in hot water do move faster, using cold water will take only a little while longer. 

What Is the Best Temperature for Washing Dishes?

Washing dishes is an essential part of keeping a kitchen clean and hygienic, but getting it just right can be tricky. The temperature of the water is an important factor to consider when washing dishes.

Too hot and you risk scalding yourself or damaging the dishes; too cold and the dishes won’t get clean as easily. So what’s the best temperature for washing dishes?

The ideal temperature for washing dishes is around 110°F (43°C). At this temperature, it will be hot enough to remove germs and bacteria and remove grease easily. However, you will need to use gloves if you don’t want to scald yourself.

It’s also important to use high-quality dish soap to protect your hands and dishes from irritation. When you’re done washing, be sure to rinse all the dishes thoroughly and dry them with a clean dish towel. 

Does Water Need To Be Hot To Wash Dishes?

The water doesn’t need to be hot to wash dishes, but most dishes are more easily cleaned with hot water. Hot water is more effective at removing grease and eliminating bacteria.

This is because the hotter the water, the greater the dissolution rate of the detergent, which means it will be more effective at breaking down dirt and grime. 

Hot water also helps to prevent staining on dishes, whereas cold water can cause particles to stick to the surface unless adequately rinsed.

On the other hand, cold water is great for washing delicate items like wine glasses or china. The cold temperature prevents the glass from becoming too hot and potentially cracking. 

Although hot water is better for most dishes, it isn’t always necessary. Cold water can also be an effective way to get your dishes clean.

Dish Soap Alternatives

Cleaning can be a chore, but it doesn’t have to be. There are alternatives to traditional dish soaps that can make the task easier and even more eco-friendly. Here’s what you can use instead. 

  • Lemon: Natural and biodegradable, the juice will help to remove grease and dissolve food particles, while the acidity will help to kill germs and bacteria.
  • Vinegar: Vinegar can be used as a degreaser and is great for cutting through grease and grime. It’s also a natural antibacterial, so it can eliminate germs.
  • Sea salt: The salt will act as an abrasive, helping to remove tough stains. Plus, sea salt is all-natural, so you don’t have to worry about any harsh chemicals.
  • Baking soda: Baking soda is great for scrubbing away stuck-on food. As an added bonus, it is also excellent at removing odors.


Cold water washing is a great way to save energy and money while providing the same cleanliness as hot water. The only catch is that cold water is not as effective at removing bacteria and germs as hot water. If you need to get rid of a buildup of mold or bacteria, opt for hot water.

In the end, you should consider the type of dish and the amount of grease to make the right decision.
