Black clothing eventually begins to fade after repeated washing and drying. Here’s an effective way to retain the colour.
1) Colour coordinated. If you are washing multiple items, make sure to load clothes of similar shades at a time. Start your normal wash cycle using cold water.
2) Brew up a pot of strong black coffee. Stronger the coffee, darker the final outcome will be. Keep that in mind while brewing. You will need 2 cups of coffee for washing, so use a full sized coffee maker.
3) Add the freshly brewed coffee to the washing machine when the rinse cycle begins. Close the lid of your washer and wait for the cycle to finish.
4) Dry. Remove your clothes and hang them to dry.
Simple and effective.
