Lacquer Thinner and Catalytic Converter

edited May 2011 in Repair and Maintenance
Is it safe to clean your catalytic converter by pouring some lacquer thinner in your gas tank and running the engine for about 150 miles as Scotty Kilmer suggests in this video?

The p0420 code came on about a month ago, and it goes off and on intermittently since then - I'm hoping that that means that the problem is fairly recent and, if this lacquer thinner thing works, will get rid of the impurities that are launching that code.

I need some reassurance or some advice before I do this.
