DIY Catalyst Clean on Citroen C1/107/Aygo. How to/How NOT to?

Using caustic soda/oven cleaner to clean the catalyst just for fun.

The low torque reference was genius 👍 really like your videos they do make me laugh 😂

[@StupidBlokeStupidVideos]

Cheers mate

[@waverider5751]

It worked for me, I found your video for validation of my own idea, which you and probably many others found first. Thanks! Glad it works, and I only gave mine a short time in the oven, 10 minutes or so, the entire oven is harder to heat than a part in the upper shelf, so it doesn’t really need much time in the oven. I could see shiny silver under the heat shield after one application.

[@StupidBlokeStupidVideos]

You can clean the outside of it too lol. Use this stuff

Haha, I just did this to my C1. I've had a faultcode P0420 for months, deleted the code many times to see how fast it was returning. It came back in a day or two. And I tried to graph the o2s2, and saw it was going up and down like o2s1.
I was about to give up and change it, but I wanted to have a look down the lambda hole, it did not look that bad at all down there, but it seemed like there was something minuscule in some of the holes. So i just said to myself f..it I'll try some oven cleaner. And it seemes like it worked! The graph got a lot better, and there is no pending fault codes and my obd2 app checked the converter with "passed" for the first time.
I can add that my car was filled up with diesel some months ago, and this may be what clogged the converter.
The oven cleaner I used was a norwegian brand called "Plumbo ovnsrens." A whole spray bottle, sprayed around 1/4 at a time and waited like 15 min between each time.

[@StupidBlokeStupidVideos]

Nice one. Oven cleaner can be good stuff for removing carbon buildup. Let us know how it goes

[@flapsfalkland5181]

As ever, informative, educational and a very clean video 👍👍

You can buy oxygen sensors sockets from halfords which have a cut out channel for the cable. Makes life very easy

[@StupidBlokeStupidVideos]

Yes, I used to have one in a previous life but I dunno what happened to it

[@declansgamereview6523]

I actually tried the same thing last week but it was too tight. My plan was to open up the bottom flange and stick a hose pipe though the sensor hold ( i want water to come out of the bottom instead of getting caught in the exhaust system ). Anyway im going to try to get a better 22mm

[@StupidBlokeStupidVideos]

Let me know how you get on if you have another go at it.

[@AHMEDHUSSEN8482]

Have you done it through the bottom flange,👍

Would you do a video on using Mr. Muscle all underneath the car in prep for anti-rust spray, such as Lanoguard - or a video along similar lines?

[@StupidBlokeStupidVideos]

I’m not sure it’s the best thing to use on bodywork, it’s quite corrosive I think 🤔

[@MrGrtx]

Great videos just asking ive got to renew my downstream o2 sensor what brand would you recommend. on a c1 mk2 Thanks

[@StupidBlokeStupidVideos]

I’ve usually always used NTK with no issues, but ant should be fine really. The downstream one doesn’t do that much

Why there are some smoke from the oxygen sensor after I used this method?

[@StupidBlokeStupidVideos]

@@lerryng3791 will probably just be burning off any dirt/oil you’ve got onto it from your hands when you took it out

[@atoyran6584]

Hey bud, when i drive for 5 mins. The hole car smells like burdes gasoline and oil, if i pop the hood there is a strong smell coming from the catalyc converter. Could it be that my catalystic us dead or can is try this method?

[@StupidBlokeStupidVideos]

More likely that you have an exhaust leak by sounds of that

[@declansgamereview6523]

Ok I did this but I poured in engine cleaner and stuck a hose pipe in afterwards. I opened the bottom flange below the catalytic convertor so the water could run out cos its not like I could lift my car up in the air to let the water out

[@StupidBlokeStupidVideos]

That’s a good idea

[@AndrewPattullo]

Done mine left oven cleaner 30mins as reccomened on can.... done it 10 times.. and now clean...

Sweet. Did it solve any catalyst efficiency fault codes?

Hi, thank you for the reply . I done what you mentioned it did take the engine light fault for few days and it came bk !!. I also heard someone say using oven cleaner can do damage to engine is that true . Many thks

[@StupidBlokeStupidVideos]

It shouldn’t really do any damage as it’s not likely to get anywhere that can be damaged by it tbh

So the video might not be as silly as it seems!

[@StupidBlokeStupidVideos]

Yea if it’s blocked up from burning oil, which these things do from time to time it could work well to clean it out. I’ve used oven cleaner in that long of crud before and it’s worked extremely well so I thought it was worth a go just to see what the effects were to be honest.
