This stuff seems to clean anything. I had scuffs in the plastic on my side panels that were filled with dirt and oil, a little on a rag and it was gone

It got most of the varnish out of a carb that sat for 3 years, but its not a replacement for a good dipping solution. Makes the outside of the carb shine though.

I use this as a preventative maintenance item. I run it through my tanks 1-2 times per year. I've had no issues with clogs.
