No way.The only way to clean out the converter is take it off and knock it out or replace it.

Yes, there's a video about it on youtube. Under the comments sections of the video there's people who claim it works. There's also a product called "Cataclean" that works. We sell it at NAPA, where I work. A few of our customers have used it with good results. Are you getting a trouble code P0420? HTH. -Jim
