NOTE: I need everyone to understand that I KNEW AHEAD OF TIME THAT THIS CATALYTIC CONVERTER COULD NOT BE CLEANED. This cat had a degraded catalyst. I could see that before I started. I was trying to go to the extreme with this little experiment trying to "clean" it to show you that it wouldn't work because the catalyst was already gone. I obviously should not have been so sarcastic in my tone because a lot of you didn't understand the entire point of this video. I get comments on alternative cleaning procedures and I get comments on how putting lacquer thinner in the gas tank did solve their problem. NONE OF THAT WOULD HAVE WORKED FOR THIS CAT. If you understand that, then I think you can enjoy this video for what it is. Not every cat will be like thissome cats may actually be dirty and perhaps other methods may be successful in cleaning them. Let us know in the comments if you've found success in cleaning your dirty cat. All that being said, hopefully you have learned something about degraded catalysts.

BE CAREFUL WHEN USING SODIUM HYDROXIDE!

I feel like I can't say that enough.

But that said, join me as I attempt to clean a nearly dead catalytic converter and see if that will get it to work again.
