    Lambda sensor - cleaning advice

    I want to clean my working lambda sensor from the carbon dioxide and dirt that has been build in the past few years. Is there any solvent I can leave it in for a day or two and get a good result? All I'm trying to do is while the car is not drivable to freshen things up.

    Thats a cleaner for carburetors yes? Do I just soke it in and leave it for over night? Or maybe I need to open it up and use a tooth brush to remove the dirt from inside?

    Are you pulling my leg or does that actually work? I've got plenty of both where the carburetor cleaner I'm gonna have to buy. If thats correct I will do it today.

    vinegar, yes, we sometimes use it to clean carbon of gun parts

    coke is also good for removing rust

    All done and very pleased! I found some 8% vinegar in the cupboard, filled up a glass and left it to soak in from 10am till 5pm. Occasionally I would stir to make sure the residue falls and eventually I used a tooth brush to clean it from the outside. After lunch I got the jet wash out and rinsed it so all the carbon is forced out. Dipped it back in the vinegar for the remaining time (cleans the water off, so no rust after this) and it came out as a brand new lambda sensor. Fitted it right back in and now I don't have a clue if it's working or not, because the car is not running. Hehehe
    Thanks for the idea Drift Lexus. I can buy you a can of coke now because I saved on! :P

    Sorry I haven't read your reply as I skip on the technical section as I'm busy working on my car. To sum this up yes it does you can use vinegar, but the small % of acid means having to leave it for a day rather than couple of hours. soaking it up in brake cleaner (carb cleaner same thing really) might be even better idea. I've done 3 so far including mine and the 2 (E36 318is; Audi B5 2.5TDI) came back to life after showing faults and again I just left them in vinegar for 2-3 days. I hope this info helps.

    p.s Just follow the technique I posted 2 years ago.
