Kids' Laundry Temperature - Hot, Warm, or Cold Water?

Washing Kids' Laundry - What's the Best Temperature?

Washing our kids' clothes and undies can be a chore. Most items are not really delicate, but we still want to keep them looking good and fitting well wash after wash. We've put together some guidelines to help you choose water temperature and detergents so their clothes last long enough to hand down.

Cold Water is the Best for Kids' Clothing

Cold water (60° - 80° F) is the best laundry temperature in most situations, according to Consumer Reports. Due to changes in laundry detergents and washers over the past few years, cold water will handle most of your laundry needs, including all types of underwear. New machines and detergents are designed to work at environmentally friendly cooler temperatures using less water. Cold water has many advantages:
  1. More gentle on fabrics
  2. Doesn't cause color fading
  3. Less likely to cause shrinkage
  4. Works best on certain stains such as blood
  5. More environmentally friendly

Cold water is the quickest laundry cycle, and also the one that uses the least amount of energy. It works well for more delicate fabrics that are more prone to shrinkage and fading.

But sometimes your kids' clothes have a stain, and a cold cycle will not do the whole job. If a stained garment must be washed with cold water, you might need to pre-treat it to get out tough stains.

All Lucky & Me care instructions recommend using cold water. The actual instructions are: Machine Wash Cold and Tumble Dry Low. Using cold water for cotton and cotton blends keeps fabrics plush and colors vibrant. If you choose to use cold water for the majority of your loads, make sure you use a detergent that works well in cold water.

Hot Water for Kids' Undies

If you need a really deep clean, the best laundry temperature is hot water (130°F or more) . This option is best when clothing is heavily soiled, and the fabric can stand the heat. Delicate underwear fabrics and garments prone to shrinkage should not be washed in hot water.

If those types of items get really dirty, it’s best to pretreat them with a product such as Oxiclean, and avoid hot water. If you want to be environmentally friendly, hot water is not the best choice, as it uses the most energy of any type of laundry load. Use hot water for:

  • Whites
  • Colorfast underwear
  • Sturdy clothes that are heavily soiled

Be aware - hot water will not sanitize. For the type of clean needed when a child or family member is sick, or for underwear items that really need a more thorough cleansing, you will need to use the sanitize option on your washer.

Another option is to add bleach to the wash - but make sure to test the fabric for colorfastness. More information on using bleach to disinfect laundry items is available here.

Warm Water for Soiled Kids' Clothes

Warm water (90° - 110° F) is a happy medium laundry temperature. I confess to using warm water on my kids' clothing and my own colorfast work-out clothing. Warm water works better in older style machines and with powder detergents. And it doesn’t have the potential to shrink or fade clothes like hot water does. It’s great for towels, jeans, and other sturdy clothing that isn’t super dirty.

Make sure the colors you put in don’t have a tendency to run, and aren’t too delicate. Use warm water for:

    • Towels
    • Jeans
    • Moderately soiled clothes

Follow the Care Instructions

Do your best to follow the care instructions on your clothes, and pay attention to what works and what doesn’t. If you have a tendency of just throwing in a load without really paying attention to water temperature, you run the risk of prematurely aging your kids' clothes, or even ruining their favorite t-shirt!

Clothes will come out cleaner and last longer if you follow these simple guidelines on laundry temperature.
