Short answer. A simple enzyme detergent is enough. Skip dye-stripping ‘sport’ formulas unless you like faded teal.
The only routine that matters
Inside out, cold, darks with darks, low heat. That is the entire Yireh care philosophy. You bought the color on purpose — treat it that way in the laundry room.
Burgundy, teal, and royal blue especially do not belong in a hot load with towels.
