So far...no cleaning. Got it. Still gonna press forward with my project.
Cleaning process should work on O2 sensors as well...but since they are cheap enough (less than $100 each), why bother.
Why wait until the catalytic converter throws codes if yer gitting instant higher MPG and HP? When you git a brand new (or new to you) car, just drop it the converter down (bolts aren't even rusty yet on a new car) and bust that sucker out! Better MPG and HP over the stock numbers!
High heat doesn't keep the converter clean...really. Build up will eventually clog the converter as I believe it doesn't happen in a linear fashion. Same thing goes fer air and oil filters.
I'm not using just water...I'm using a heated weak ~0.1 M citric acid and oxalic acid solution that I'm gonna cycle through the catalytic converter. I haven't see what the grid of a converter looks after 380,000 miles yet... I did find this on the internet...not sure on the mileage or what brand/type of gasoline that was used on it.
