Intention: An act about to clean up something, but using dirty tools, then what happens is not to produce something that is clean, even more dirty. The message of this proverb is so good goal should be reached by way of a good also, and if in achieving that goal must use the tool, the tool used must be clean, because when using a method or tool that is not clean, then there could be counter-productive.
