I had the same question, If you look at #109 on the HB store it says 1oz. to 32oz. some other place it gave a different ratio. I called corporate and talked with John. He sent me a bottle and suggested I try a little stronger ratio for a trial. We mixed (wife and I) a ratio of 2ozs. to 32ozs. and have used it for a week. The results are FANTASTIC, have used on house windows, my truck windows, counter tops (porcelain) and all stainless appliances in kitchen. I’m about to write all my people in Florida an e-mail about this product, They should be able to sell a “ton” of this product. Thank You Corporate for such a great product!!!!!
