Just got done with the 2nd wash and backflush. I ended up heating the solution on my induction burner fer the entire solution...talk about hot!
Here's the final result after two 2-hour washes with a citric and oxalic acid solution. A simple rinse from front and from the back. Used my shop vac in blower mode to blow out as much water as I could...
Used 2 new OEM gaskets along with some anti-seize. Shouldn't have to worry about someone taking off with my converter as I also have a full belly pan and side skirts fer them to contend with as well.
If I were to redo this...I think I would try a hot sprayer method instead of the full flow method. At least on the 2nd wash it could be more efficient as I could point the sprayer at the spot(s) I wanted to dissolve away. Of course...with the full flow method I could've washed the converter fer hours on end instead. I just needed a better way of keeping the solution at temp. I did rotate the converter at 90° every 30 minutes so I could git enough coverage.
I did notice after I started up the engine I was gitting water vapor from the exhaust pipe...like when the weather is cold outside in the morning...except it's 82°F and super humid from all the rain. I wonder if that's a testament to the effectiveness of the converter.
