The best laundry detergent for black clothes is Woolite Darks Laundry detergent.
I use Woolite regular laundry detergent for cleaning most of my laundry but when it comes to washing dark or black clothes I use the Woolite Darks laundry detergent.
The Woolite Darks laundry detergent is specially formulated and made to clean dark or black clothes.
You can also use the Woolite Darks laundry detergent on other clothes as well but I prefer to use the regular Woolite laundry detergent for cleaning the other clothes and save the Woolite darks for black clothes.
Another good laundry detergent that works great for cleaning black clothes or dark clothes is Tide Darks and colors laundry detergent.
Tide is a wonderful laundry detergent but I started using Woolite and love it much better but they both are good brands of Laundry detergent.
