Muffler decoking
Does anyone have a recommendation on how to clean the black oily spooge from mufflers that doesn't involve burning? Thinking about caustic soda. TIA.

Re: Muffler decoking
There are several methods, burn them, use acid, I just remove them and remove carbon build up in header pipes, someone mentioned to use an old cable in a drill with the strands separated.
I don't even remove baffles unless I suspect issue, the plates that hold the baffles in place tend to brake loose and fall out of position, when this happens the baffles will do nothing anymore.

Re: Muffler decoking
I was concerned about using lye and damaging the chrome. So, I went with Superclean degreaser. Stood the mufflers on one end (plugged), in a bucket and filled them with full strength Superclean. Let sit for a day. Looked like a thick latte when I dumped them out. Flushed with a garden hose for 5 minutes, and let dry in the sun. Definitely cleaner inside. Let's see if she runs any better.
