How much of the solution to put in the machine before adding the water in the tank Pet Stain & Odor 2x?
Answer: BISSELL has taken the math out of the equation! We conveniently feature a fill line on the solution/clean water tank. This will help you determine how much water to add. First start by using a standard liquid measuring cup (or cap on formula bottle), measure 4 oz of formula (2 caps full) and pour into the tank. Then fill with hot tap water to the WATER fill line. Replace and tighten the cap and you are ready to go!
