It's faster but not necessarily more effective so long as you are patient and thorough.
If you have the traditional 5 gallon colema bucket, hmmm... I wouldn't do a 5 gallon ACV colema, that's probably too much. Do a flush with just salted water, and after using up most of the bucket, then add just a bit of ACV and see how you do with it. Most people find that just a couple tablespoons in a quart of water is quite enough.
