hi gfh,
other than the smell, which is better than the original, i believe
that the legends cleaner is one of the best, if not the best.
in not only "deep cleans", but also takes off belt marks and other
grime and dirt.
regarding clean n' dull, the residue that is left on the ball needs
to be wiped off with a wet towel or rag. this simple process removes
the residue, but doesn't affect the balls "new" tackiness and reaction.
if i'm not mistaken, it also explains this process in the "directions
for use" on the back of the container.
hope this helps.
