Detail Guide: Clay, Wax, and Polish for New Luxury Cars

When you spend a lot on new luxury cars, you want to keep them as pristine as possible—unfortunately, that requires more than just soap and water. Walking through the auto car aisle of any store can confuse even the most car savvy of individuals. Should you polish or wax? Is there a difference? What comes first? And why is clay sold next to them? Surprisingly, there are few guidebooks. Most packaging just markets itself, and it’s hard to know what’s the best treatment for new luxury cars. Opinions differ, but we’ve got a few of our own, including the use of that strange auto clay.

Polish and wax aren’t the same things, even though a lot of companies have made the two products almost indistinguishable. A lot of polishes market themselves as protective gels, but as their name itself implies, their only true purpose is to bring out a vehicle’s shine. After a wash, they work to remove light scratches and swirls, producing a glossy surface. Wax, then, is applied to protect the vehicle, creating a buffer from the environment that helps new luxury cars remain clean and clear for a much longer period. Even people who already knew this difference thinks the story stops there: wash to remove obvious grime, polish to bring out a deeper gleam, and then wax to sustain that shine for as long as possible. That’s incomplete, though, because there’s another step that keeps paint new and reflective: the strange third product, auto clay.

If you wash your car all the time and still feel bumps, uneven marks, it’s not because you didn’t scrub hard enough. Even new luxury cars begin to accumulate pollutants in the air. You see dust and pollen, but tinier contaminants are out there: fallout, brake dust, tree sap, all of which will bond to the actual finish in your paint. A standard wash can remove these materials if treated immediately, but we do mean immediately. Once they harden, the bond is established, and soon the smooth, glassy reflection of your paint disappears. After investing a lot in a luxury car, you don’t want that to happen, but it’s preventable and treatable through waxing.

Wax and polish create a sheen that anyone would love to have on their car. Unfortunately, the bumpy contaminants prevent polish and wax from reaching their full potential. After you wash, but before you begin to polish, use a clay product to go over your whole vehicle. Every surface will accumulate contaminants, but it really doesn’t take too long; most new luxury cars can be “clayed” in less than thirty minutes. Most car owners shouldn’t have to clay with every wash, but it all depends on the environment where they live. Some people may only need to use a clay bar once a year, but for others there might be more natural and artificial pollutants in the air, which would require more regular clay treatments. The best litmus test is running a hand over the car’s surface. If it’s bumpy, it’s time for clay. After that, standard waxing and polishing will work much more effectively, and new luxury cars will keep looking brand new.
