I see these two terms used interchangeably all the time, so I thought I would provide some insight on the differences between a POLISH and a WAX. I'm going to try and keep it as simple as possible...
generally contains abrasive particles
(used for removing oxidation and swirl marks) or chemical cleaners
(used for removing embedded dirt, road film, and old waxes), and sometimes both! A polish is what you use before you wax.
, whether a natural (carnauba) or synthetic (man made ingredients) formula protects and enhances the finish. Unless your RV is brand spankin' new, you should always use a polish before you wax. The cleaner the surface, the better your wax will adhere and the longer it will shine.
An AIO (all in one) and a cleaner wax are a combination of a polish AND a wax. These are especially popular for boats and RVs because they clean, polish and protect in ONE step. Who wants to perform two steps on something as large as a boat or an RV?!
Unfortunately there's no written rules on what each manufacturer can call their "polish" or "wax", so some actually misrepresent their product by using a name that isn't necessarily applicable to the chemical inside the bottle. When a product is called a "polish" it's safe to assume that it doesn't protect the finish. If it does, then it's either an AIO (all in one) or misnamed.
