Its ease of use is another advantage, requiring simple steps of application, rubbing, and buffing to achieve a bright luster.

On the downside, the cleaner comes in a pack of 12, which might be excessive for individual users who do not need large quantities. Additionally, the liquid form may require careful handling to avoid spills.
