I have a big commercial job with olefin loop pile hallways that are really hammered. I usually use a pump up sprayer for all my jobs, my carpet cleaning buddy let me use his 7 quart 9 to 1 hydroforce inline sprayer to save some time. I called Cobbs and they told me to mix 2.5 cups in hot water. I wanted to check with you guys here. I was going to boost with some citrus too but not sure how much do put in? I'm going to prescrubb with my 175 and post bonnet too. Thanks,
