I washed my cat a couple of years ago. Luckily my entire downpipe fits in my tub. I ran the hottest tap water through it for a while. Then put in some laundry detergent. I swished that around for a while and let it soak for an hour or so, occasionally swishing it some more. Then I ran more hot water through it for a while.

I let it dry and then put it back on my car. It's been at least a year and a half, maybe two, with no code thrown.

Here is a picture of the downpipe with cat that shows how I was able to let the cat soak properly.



I'm surprised the laundry detergent even removed those burned deposits. I figure with the oxylic acid or citric acid that the chemical reaction to the deposits would have a better chance of removing them. Too bad you weren't able to fit a camera into the pipe to shoot some before and after piccies of the catalyst. Wink Smile
