Our 8x Laundry detergent is formulated for approximately 12mL of detergent per average load.  A teaspoon is about 6mL. Our pumps dispense approximately 2-3mL per stroke. We suggest using between a teaspoon and tablespoon for our 8x laundry liquid. The suggested measure will vary according to the age of the washer and front load vs top load. We suggest 25-50% more detergent is required for top washers due to the washing type and potential  age of the washer. For new users to our product line, we suggest testing a higher volume initially and cutting back on later loads till a satisfactory level is reached. We would hate for a new user to use too little and be disappointed with the product performance.
