Solved How To Clear A Clogged Catalytic Converter Car And Truck

Chosen Solution

My secondary catalytic converter is clogged coming from the exhaust manifold down past the first catalytic converter into the second one I’ve removed it tried to spray brake fluid in it any advice

Clogged catalytic converters typically aren’t cleaned, they’re replaced. Once a cat gets clogged the exhaust is able to superheat the catalysts inside, melting/fusing them together and creating a more significant blockage. There is no saving it; it must be replaced. Ghetto “workarounds” – none of which are recommended – include removing the O2 sensor in front of the cat (will cause performance and emissions issues, also illegal), banging hard on the cat with a hammer to break it up and then starting the car to blow out the broken pieces (more performance and emissions issues, also illegal), removing the cat and soaking it for a day in either a heavy concentration of Dawn dish detergent and vinegar, acetone, or sodium hydroxide – none of which are really effective and sodium hydroxide is pretty nasty as well. Here’s a reasonably good video about “cleaning” a catalytic converter: https://www.youtube.com/watch?v=L_QIRFUg…

I recently used cataclean to get my car through a failed MOT on bad emissions. After burning that tank of fuel I got the car retested and it was a lot better. I only paid £15 or so for the cleaner also - https://www.motorverso.com/catalytic-con…
