This is the best guitar cleaner we have used as it cuts through all the filth and grime well used guitars seem to attract. The cleaner is great on lacquered finishes and brings up a good shine but for a really high shine polish you may want to use a dedicated polish, however, most of the time this one cleaner does the job. Its also great on hardware, plastics and fretboards so if 'convenience' is your priority, a bottle of this will usually do the whole guitar. The 16oz bottle is significantly better value than the little bottles and it comes with the handy sprayer make life even easier. We have used this on over 1000 guitars with great results and would not use anything else for convenience, quality and price!
