Expert Q & A …. Safe Chemicals to Polish Aluminum Rims?

Many of the aluminum wheels and parts out there, aren’t just made of aluminum, they’re what’s called, aluminum alloy. (Which means they contain other metals, and are yet, aluminum based.) So, even though a product may claim to be safe for aluminum, that doesn’t necessarily mean it’s safe. That is why every manufacturer suggests testing products in inconspicuous areas. Every chemical has the ability to compromise appearance and finish. In fact, if one has used chemicals, professionals will most likely have to sand the rims, before they can begin polishing, to remove the (sometimes deep) imperfections chemicals can leave. In addition to those imperfections, chemicals can also open pores on the metal, making it difficult to create the desired results.
