Disinfect Laundry

Disinfecting laundry can be an important part of keeping it fresh and clean, so everyone in your household stays healthy. Using bleach in your washer's cycle or to soak your laundry in prior to washing is an extremely effective way to sanitize cloth diapers, towels, bedding, and other items. However, not all materials can be treated with bleach, and your washer may not permit its use either. Fortunately, there are other agents, such as hydrogen peroxide and borax, grapefruit seed extract, tea tree oil, and lavender essential oil, that can also help disinfect your laundry after it's been exposed to germs or unsanitary conditions.

Steps

Killing Germs in the Washer with Bleach

1. Set the washer to the highest temperature possible. When you’re disinfecting your laundry with bleach, you want to wash at the highest temperature possible. Check your items’ care labels to determine how hot the water you wash them in can be, and use that setting on your washing machine.
   • Hot water, measuring 140 to 194 degrees Fahrenheit (60 to 90 degrees Celsius) is typically only used for white items.
   • Colored items should be washed in cooler water, typically measuring between 86 and 104 degrees Fahrenheit (30 to 40 degrees Celsius).
   • Delicate items usually should be hand washed or washed in a strictly cold water cycle.
2. Add the usual amount of detergent. Once you’ve set the proper temperature for the water, fill the cap from your detergent with the recommended amount for the size of your load. Pour the detergent directly into the washer’s drum or into the detergent drawer.
   • If you’re not sure where the detergent goes in your washing machine, consult the operating instructions.
   • Front-loading washers usually have a detergent drawer, while top-loading washers usually call for pouring the detergent directly into the washer’s drum.
3. Fill the bleach dispenser in your machine. Consult the instructions on the bottle of bleach to determine how much you should add for the size of your load. Next, pour the bleach into the bleach dispenser.
   • If your washer doesn’t have a bleach dispenser, you can add the bleach directly to the drum. However, you should start the cycle first so water starts to fill the drum before pouring the bleach in. Don’t put laundry in a washer with bleach that hasn’t been diluted first.
   • Pay attention to the type of bleach that you’re using. Chlorine bleach is best for white items, while all-fabric bleach should be used on colored items.
4. Add your laundry and allow the cycle to run. Once you’ve added the detergent and bleach, place your laundry items in the washer’s drum. Close the lid, and allow the cycle to run through as it normally would. When your items are finished washing, dry them according to their care instructions.

Soaking Items in Bleach to Kill Germs

1. Combine cold water and bleach. To create a bleach solution to soak your laundry, you need to dilute the bleach with cold water. The amount of bleach that you need depends on how large a load you’re soaking. Add 1 tablespoon (15 ml) of bleach for every 1 gallon (3.8 l) of cold water up to 5 gallons (19 l).
   • Make sure to choose the right bleach for your laundry. Only use chlorine bleach for white items. Use an all-fabric bleach for colored items.
   • Make sure that your laundry has already been washed before soaking it in the bleach.
2. Soak the items in the bleach solution for at least 15 minutes. Once you’ve created the bleach solution, place your laundry in the water. Allow the items to soak in the water for at least 15 minutes.
   • If you’re soaking laundry that is especially prone to germs, such as cloth diapers or an ill person’s bedding, you should let it soak for at least 30 minutes.
   • Never leave the laundry in the bleach solution for more than 45 minutes.
3. Rinse the items with hot water and wash them in your washer. After your laundry has soaked for the appropriate amount of time, use hot water to rinse them thoroughly. Next, put them in your washer and wash as you normally would with hot water to completely remove the bleach.
   • Be sure to read the care labels on your laundry to verify that they can be washed in hot water.

Using Non-Bleach Methods to Disinfect Your Laundry

1. Wash or soak your laundry in hydrogen peroxide and borax. If you don’t want to use bleach to disinfect your laundry, a combination of hydrogen peroxide and borax can also do the trick. You can create a solution to add to a load of laundry or soak your items in it to sanitize them.
   • To wash your laundry with a disinfecting hydrogen peroxide and borax solution, mix 4 cups (960 ml) of hydrogen peroxide and 1 cup (409 g) of borax along with your usual detergent. Make sure to add the mixture to your washer after there’s some water in it, though.
   • To soak your laundry in a disinfecting hydrogen peroxide and borax solution, mix 4 cups (960 ml) of hydrogen peroxide and 1 cup (409 g) of borax into a bathtub that’s half full with water. Allow the items to soak for 15 to 30 minutes, rinse in hot water, and then run through a cycle in the washer with hot water.
   • Be careful when using hydrogen peroxide on darker colors. Test it on an area of the fabric that won't be visible before using it.
2. Soak items in a grapefruit seed extract solution. Grapefruit seed extract is believed to be a natural disinfectant. Create a solution using 5 to 10 drops of grapefruit seed extract for every gallon of water. Let your items soak for 15 to 30 minutes, and rinse with warm water. Next, run the laundry through a regular cycle in your washer.
   • Don’t allow your laundry to soak in the grapefruit seed extract for more than an hour.
3. Add tea tree or lavender essential oil to your washing machine cycle. Like grapefruit seed extract, tea tree oil and lavender essential oil are believed to have natural antifungal, antibacterial, and antimicrobial properties. While you’re doing a regular load in your washing machine add 2 to 3 drops of tea tree essential oil or 1 to 2 drops of lavender essential oil along with your detergent. Allow the cycle to run as normal, and dry the clothes according to the care label when you’re finished washing them.
   • Because tea tree oil and lavender essential oil have fragrances, it’s best to use them with unscented detergent.

Tips

• It’s a good idea to disinfect the laundry of any in your household who’s been ill.
• Some people are allergic to bleach, so you should check that no one in your family has an issue with it before washing their laundry with it.
• You may also want to use a disinfecting agent if you’re washing your clothing in public facilities, such as a laundromat.
• Certain detergents work optimally while being used with a particular temperature of water. If your detergent works best with water of a certain temperature, use that temperature instead of one that is too hot or cold.

Warnings

• Some manufacturers do not recommend using bleach in their washing machines. Consult your owner’s manual to see if you can use bleach in your model before adding it. Using bleach when you shouldn’t may void your warranty.
• Don't add bleach, hydrogen peroxide, borax, or essential oils to a washing machine without spot-testing on small parts of your clothes first. You'll need to verify that clothes don't react negatively to contact with them or you may damage your clothes.
