The inside of the catalytic converter is made of ceramic material. How to clean it without damaging it?

Normally they work just fine. If they get clogged, it is best to replace them.

That will be expensive

Youtube is your friend. I found a couple of videos on how to clean them using lacquer thinner. Look at the one by Scotty Kilmer. I don't know if it will work. Probably best to just replace.

If lacquer thinner doesn't work, use xylene from the hardware store but do it out doors for safety's sake

How do you know it’s clogged up? Why does it need cleaning?

Under federal law, the catalytic converter and engine-control module are covered for eight years or 80,000 miles. Some other emissions parts carry shorter federal warranties, usually two years or 24,000 miles.

How old is your car?

Eight years? That's good to know. Thanks!

Question: Assuming that you're using the proper fuel; why would they clog up?

 

[strelnik]

I discovered that there's more bad gas in some stations where the PREMIUM fuel is not used as often and stays as long as 4 months between replenishments. How do I know? I asked the gas jockeys at the place.

Good point... Thanks!

For the past 30 years I have used Shell almost exclusively in all my vehicles. That covers more than 10 over that period of time. NEVER a fuel issue! During the past 7 years of smart ownership most of my fuel has come from a handful of local Shell stations. All of them do a booming gas business. I haven’t positioned myself for a day at a station to record how much premium was pumped but I doubt any of it stayed in the tank for very long. Can’t speak for other stations in other areas.
