Since I am cheap I was looking for a way to maximize this product. I found a spray bottle and mixed about 3/4 oz with 27 oz water. rinsed the car as normal with water. Just 3-4 sprays per panel, and 2 sprays on the mitt to start. The wash mitt still gets a bucket of water for rinsing. I am pretty sure this way i could use a fraction of a oz per 27oz water and still get excellent results. It looks like i can probably wash all 3 cars witb less than a 1/2 oz of soap. Should help keep the bucket cleaner since its just rinse water I can just dump and refill with plain clean water at any time. I keep watering down the spray bottle content as it gets lower but oddly as the soap ratio gets smaller the application gets better. After the last watering down it came out in a foamy mist. Its probably 1 table spoon/27oz water.
