* If necessary, the soaking time can be extended appropriately. If the color stain is not removed after 2 hours, take out the clothes, put the white clothes into the basin (add 1 bottle cap to each half basin of water), stir them evenly, and continue to soak them in the clothes for a cumulative soaking time of no more than 6 hours.
