I’m not a big fan of products that purport to do multiple things. Few of the combination printer, copier, fax and scanners that I’ve owned have been as good as the dedicated machine for each task. So it is in car care too, where all-in-one cleaner waxes go up against multiple product systems that involve a separate polish and final wax. I generally find cleaner waxes to be less effective than a separate polish followed by a non-cleaner wax topcoat that acts as protection only.
