Get a piece of PVC pipe, put an end cap on it, fill with a mixture of TSP & water, let soak overnight, then rinse with clean water. Should get the oil/crud out and leave the barrels very clean.
Ive tried Laurel Mountain solution; I always seem to get copper colored splotches when using it. I believe that they use copper sulfate in their solution. Guess I was doing it wrong.
Finally started making my own that Im happy with.
To remove water between ribs & barrels use denatured alcohol, acetone will not remove water.
