Enthusiasts have much more holistic views, as they have literally seen and used it all. These are
fairly authoritative and reflect the current enthusiasts' understanding on the panoply of detailing products:
The distinguishing feature of cleaner waxes is actually the cleaning chemicals. But as it says, there is no industry standard for these terms so you have to classify the product by what it does.
So ... just because turtle wax original is not called turtle wax cleaner wax, does not mean it is not a cleaner wax -- they just did not change the original name since the point of still having the product is to provide the same familiar thing. It likely contains light abrasives in it ("contains no harsh
abrasives"). The actual product labeled "cleaner wax" may contain more abrasives or a different formulation of solvents which is possibly more effective, being a newer product.
Anyway, we have strayed. Car wax science is kind of incredible today. But it still doesn't really do anything helpful for barrels, and adding another maintenance procedure sucks.
I've yet to see any barrel ever really "shoot clean" though as a pump player my standard of what shooting-as-if-clean is may be higher than semi players. Actually as a pump player I rarely experience ball breaks at all.
I wonder if the prevalence of two-piece or step-bore barrels has some effect here. After all, the paint in the largebore section won't be cleaned nearly as well regardless of surface finish or treatment.
