Should I use hot or cold water to do my laundry?

Author: Kate Amore–curious laundry-doer

Have you ever wondered what the actual difference hot versus cold water makes while doing laundry? I was curious about it after trying to wash my beach towel–My dogs completely stained it by trampling over it with muddy paws. I thought the towel was ruined until I washed it with HOT water and HeySunday sheets. After doing some research, here’s what I learned about doing laundry with hot versus cold water.

What’s the difference between hot and cold water?

Hot water is more effective for cleaning heavily soiled items, but it is less energy efficient. Cold water is good for cleaning everyday items, as about 90% of energy used by washing machines goes towards heating the water. 

The Benefits of Hot Water

Washing clothes in hot water (around 130°F to 140°F) can be very effective for certain situations. It’s great for heavily soiled items like towels and bedding, as hot water can help dissolve detergent better and tackle tough stains. Plus, it can kill bacteria and allergens, making it a good option for items that need a deep clean. That’s why hot water did the trick for my beach towel. 

However, hot water can be rough on fabrics. Delicate items, such as silk and lace, may shrink or get damaged, and colors can bleed. I always check the tag before washing delicate materials. 

The Advantages of Cold Water

Cold water (typically around 60°F to 80°F) has become my go-to for most laundry loads. HeySunday laundry sheets dissolve easily in cold water, so it can effectively clean everyday items like t-shirts and jeans. It’s also gentler on fabrics, helping to preserve colors and prevent shrinkage.

Another bonus? Washing in cold water is more energy-efficient. About 90% of the energy used by washing machines goes toward heating the water, so opting for cold can help save on your utility bills. I’m certainly glad I know this before my heat bill skyrockets in the winter!

Does hot or cold water clean better?

When it comes to stains, hot water is often better for removing tougher ones, especially food and grease. But cold water can handle lighter stains just fine, especially with the right detergent. For a little extra freshness, I sometimes add a splash of vinegar to my cold wash.

Finding What Works for You

Ultimately, the best approach depends on what you’re washing. Here’s a simple guideline:

1. Cold Water for Everyday Items: Use cold for t-shirts, jeans, and lightly soiled clothing.
2. Hot Water for Heavily Soiled Items: Reserve hot water for towels, bedding, and anything that needs a deep clean.
3. Check Care Labels: Always read the care labels on your clothes for the best results.

In Conclusion

Both hot and cold water have their place in your laundry routine. I’ve started separating my laundry into hot and cold water loads so I can be more energy efficient. Understanding when to use each can help you keep your clothes clean and in good condition. I hope this helps, happy washing!
