How to Clean your Catalytic Converter & FIX P0420/P0430 at home DiY

[@dizzyaznboy]

Thanks a lot Joe. I went to Walmart to get the DMX dr mechanic degreaser. Worked perfectly. I took a whole bunch of rubber gloves and stuffed them together to make a ball and that was my dam. Then put the cat in a 5 gallon bucket and used a funnel to fill up the cat with DmX. Left for almost two days. Then went to industrial area where they have 3 inch hose, high pressure water and washed the whole thing out. Came out super clean. Im happy with the results. Thanks Joe!

I also found one of my spark plugs were super carboned. And i just replaced these like a few months ago. Im pretty sure its a bad coil because i do feel it occasionally misfire. So gonna replace that too.

Excellent! Thank you for watching

"oh yeah, thats dirty" hahaha had me rolling for some reason. Love the video, nice and clear example with two options for degreaser.

[@toasty3623]

This is what i want to do and im glad you had the same idea of just filling the cat up!

[@Pag17]

I haven't tried this with the cat, but I did do it with an EGR and acetone, which just wasn't doing the job. What did work better than anything in the end was just a power washer. It got absolutely everything out.

[@joeasbury974]

I really wish that you had shown us the intake side of the cat after cleaning. the exit side is always much cleaner to start with.

[@williamb454]

Good job man!! I gonna try it, I hope they are bolted on thou

[@sethheath9568]

Good job man. Save a bunch of money.

[@JoesFixallGarage]

Thanks, and I Hope it helps.

​@@JoesFixallGarage has the code stayed away? I cleaned my cats by adding one gallon of acetone for 6 gallons of gas then took a long drive to run the tank near empty... The code did go away and I was able to pass the emissions test here in California.. it's coming up to a year and the code came back... Toyota cars are expensive.... I would rather use your method

*Did it fix the check engine light issue?*

[@angelawillis1741]

I have a 2010 MDX, gas mileage isn't good. I was told and after googling that it's 16mpg city & 21 highway. I'm thinking about trading in for 2018: 20 city/ 27 highway. I really like my 2010...is there a way to getter better gas mileage?

[@yuutamooney7464]

did the code come back or did the cleaning work as intended?

[@JoesFixallGarage]

No the code didn't come back after re installing, I also went ahead and replaced the B1S1 & B1S2 O2 SENSORS as well.

[@nemracfiftyto6206]

Great idea, if it works. I have a 2014 Hyundai Accent with same code and engine light on. Bin driving it like this for over a year now. Still runs good, not sure weather I should do anything about it or just wait till it has a drive ability problem. Any suggestions.?

[@yuutamooney7464]

@@nemracfiftyto6206 some vehicle computers would self clear the code if you drive a certain distance if the fault itself is no longer present, but you can also check how hot the catalytic converter is getting once the engine is at operating temperature. As long as your below 1200 degrees F you’ll probably be fine.

[@mnhoss2100]

One really needs to fix the root cause before or shortly after cleaning though. They cat should not plug in the first place so if the engine is burning oil or too rich it will plug again and ruin the sensors again.

[@JoesFixallGarage]

Still code free

[@DIYTech21]

unfortunately my car has too much stuff in front of the cat to remove it. Fing even sensors are way to hard to reach and open

[@terrytrice8584]

If I'm taking it off I'm just grabbing a universal catalytic converter

[@JoesFixallGarage]

Right, that would also work. Thanks for watching.

[@JJ-yh9kf]

Can't do that in CA.

[@terrytrice8584]

@@JJ-yh9kf sucks for you guys but for those of us who can save that money!

[@armoricain]

@@JJ-yh9kf you can't do anything in California anymore! The elitist politicians are completely disregarding the cockamamie rules, regulations and laws they are foisting upon you, Californians. They demand you abide by them while having a grand ole time ignoring them!

[@mig21m13]

This is happened when you don't understand how catalytic convertor works. The name tell you very clear, "catalytic" .😂

[@anggaros1]

says a simpleton who doesn't know how to spell converter.

@@anggaros1 but he knew how to spell "catalytic" though! 😁

[@TylerRivera635]

If DPF cleaning is a thing, I don’t see why this wouldn’t work.

[@JoesFixallGarage]

Right, Super Clean is a powerful well none degreaser, so I said why not try it on this catalytic converter, it didn't disappoint.

[@blkpryde2thamaxx]

Thanks...I have a my old oem converter in my storage unit...I'm going to clean it and reinstall it...

[@j.c.9461]

Screw dat go EV man

[@JoesFixallGarage]

Hey, ain't nothing wrong with that, appreciate you watching 👍

[@realhusky]

Yeah this doesn't work. The catalyst breaks away over time and doing this is not going to help

[@pmag3200]

You are right it does break down over time but I tried it myself years ago on my Ford Mustang with 4 catalytic converters and it helped out And drove it for another 2 years until someone crashed into me.... It is a temporary fix in some cases

[@sethheath9568]

Depends on why it's not functioning.
