Try one or more of the various selective grass killing herbicide on the market. I agree quack grass can be tough to kill completely. A weed scientist told me long time ago that a 90% kill was about all to expect from one dose of Roundup. One little piece of viable rhizome and you have new quack grass plant.
What is the most abundent weed ?
