4 of 5 Should include instructions November 2, 2019
Reviewer: Denis H Gregg from Vermilion, OH United States  
Wouldn't hurt to include a printed copy of the instructions with the package, since they are not printed on the label.
Checking another copper sulfate product gives toilet bowl application for sewer system, but does not say anything about direct pouring into main line cleanout.
