- Check the label of each item before you put it in the machine. If it can’t be exposed to hot water, set the machine to a warm wash instead.
2
Place a capful of laundry detergent into the washing machine. This helps to agitate the dirt out of the clothes and removes stains. Pour the laundry detergent directly into the barrel of the machine (or into the dispenser, if your washing machine has one.)^{[2]

- If you are washing white items, consider using a laundry detergent that is designed for whites, as this helps to brighten them.
- If you don’t have any laundry detergent, use laundry powder instead.

- If you are washing delicate items, select the delicate cycle instead.
Dry your laundry as usual. Hang your laundry on a washing line or place it in the dryer. Make sure that the items don’t drip on the carpet or on pieces of clothing, as the remnants of the bleach in your wet laundry can mark fabric.^{[8]

1
Set the washing machine to a hot, long wash. Push the hot wash button and then select the long wash option. The heat of the hot wash activates the bleach and helps it to deep-clean the machine.
- Don’t put any clothes in the washing machine.
Bleach helps to sanitize the machine and reduces any lingering odors. Opt for laundry bleach instead of regular cleaning bleach, as this will be more gentle on your clothes – cleaning bleach can damage the fibers in your clothes and shouldn’t be used in a washing machine.^{[9]

Pause the cycle to allow the bleach to soak in for 1 hour. Wait 1 minute for the washing machine to fill up with water and then lift the lid or push the pause button to temporarily stop the cycle. Leave the bleach solution to sit in the machine to give it time to sanitize and clean the barrel.^{[10]

- If you have a top-loading machine, leave the lid open to allow the fumes to escape. Don’t worry about this if you have a front-loading machine – the fumes will dissipate once the cycle finishes.
4
Restart the machine to allow the cycle to finish. Press the start button on the machine to restart the cycle. This pushes the water through the entire barrel and then empties it out the pipes, which helps to clean the entire internal plumbing of the machine.^{[11]

- Bleach your washing machine once a month to keep it in stellar condition.
- You may want to run a second rinse cycle to help clean out any bleach residue.^{[12]
