Add two rounded scoops to each load of laundry. For heavily soiled or bulky loads, add one-two more scoops.
Add the detergent to the washing machine prior to adding the dirty laundry. If you forget, don’t worry! You can still add the detergent after.
Warm-hot water dissolves the detergent best, leading to a better clean. Especially if you have hard water or well water.
