Editor’s Note: MotorTrend’s gear team tests and reviews every recommended product. Read more about how the gear team tests products.

If you saw our recent air blower test, then you know DIY detailers are the minority in the American car community. It’s not rocket science that most enthusiasts are more concerned with driving their cars than cleaning them—we get it, and we salute those who love to drive their automobiles. But there’s never been a better time to start thinking about stepping up your car care routine with a dual-action polisher.

Modern technology has dramatically simplified the detailing process for even weekend warriors like me and you. That’s why we put together a comprehensive list of the best beginner-friendly polishers to help you dip your toe into the next level of detailing. Below are some of the best car polishers we found and put to our latest MotorTrend test.

What We looked For

Polishers are an interesting product to evaluate, as most of the metrics that differentiate these products are subjective. However, we went a step further to identify more objective differences, such as how much each unit weighs, each machine’s natural balance point, and the amount of noise each polisher emits. As you might imagine, it’s not rocket science. However, things get a little more nuanced when we start talking about the type of polishers we’re testing here.

All these polishers are dual-action, meaning the pad rotates and oscillates—orbiting around a central point. Many of the old rotary polishers aren’t nearly as easy to use as today’s more beginner-friendly equipment, which helps make the entire process far more accessible for novices to perform well and with less effort than in the past.

Here’s a more detailed list of our expectations for the test:

• Dual-action polishing mechanism
• 3-, 5-, or 6-inch backing plate
• Sound level should be reasonable to prevent hearing damage
• Ergonomics should be well thought out

The Reviews

[Best Overall] Adam’s Polish Swirl Killer Pro

BUY NOW ON AMAZON

VITAL STATS

• Backing plate: 5 inches
• Throw: 15mm
• Weight: 5.5 pounds
• Balance point: 6.5 inches from leading edge (polisher is 16 inches long)
• Noise: 88.6 dB

We’re pleased to report that Adam’s Swirl Killer Pro does indeed kill swirls. But our positive experience with the SK Pro is much more nuanced than just ridding paint of swirls and scratches—every polisher we tested can do that. We think Adam’s polisher is the best because of how well it’s designed and built.

Starting with the fundamentals, it features a 15mm throw (the distance the pad orbits around the center axis), which makes it very forgiving for beginners. Its relatively long throw, combined with its 5-inch backing plate, gives you a great balance of power and control, meaning you’ll have to work pretty hard to burn through the clearcoat of any car you’re working on. That doesn’t make it impossible, but we literally polished the test panel with toothpaste, and the end result was indistinguishable from some of the other areas we worked on.

It’s worth noting that the SK Pro’s 25-foot cable is removable, making it an easy swap if it ever starts fraying or gets damaged. You’ll notice some of the other polishers on this list include removable cables, but not all of them. Well done, Adam’s.

[Best Cordless] Milwaukee Random Orbital Polisher

BUY NOW ON AMAZON

VITAL STATS

• Backing plate: 6 inches
• Throw: 21mm
• Weight: 8 pounds
• Balance point: 11 inches from leading edge (polisher is 19 inches long)
• Noise: 82.6 dB

It seems like Milwaukee makes everything nowadays. What’s even more impressive is that it’s good at it, and the brand’s cordless random orbital polisher is no exception.

This polisher’s 21mm throw gives it the largest toss of all the polishers we tested. That makes it a great option for beginners, especially with its 6-inch backing plate, letting you cover a ton of ground quickly while minimizing the risk of blowing through your clearcoat. Despite its forgiveness, it isn’t inherently gentle. We tested it with a 6.5-inch Griots foam pad and achieved comparable results to even the best-overall Adam’s SK Pro.

The elephant in the room? The Milwaukee is eye-wateringly expensive—even before you buy a charger and batteries for it. Still, while that might be prohibitive for beginners, it’s an exceptional detailing tool if you have the cash on hand.

[Best For Beginners] Griots Garage G9

BUY NOW ON AMAZON

VITAL STATS

• Backing plate: 6 inches
• Throw: 9mm
• Weight: 5.12 pounds
• Balance point: 7 inches from leading edge (polisher is 12.5 inches long)
• Noise: 88.3 dB

Griots Garage might not have the same brand recognition as some of the other competitors on this list. But as you may have noticed, that doesn’t necessarily mean its products are subpar—quite the opposite. The Griots G9 isn’t the best overall, but it’s super close and costs significantly less than the winning polisher from Adam’s.

The G9 is a short-throw (9mm throw) polisher with a 6-inch backing plate that accepts 6.5-inch pads. The combination of a short throw and a bigger 6.5-inch pad is pretty clever, as it’s plenty forgiving but still cuts fairly efficiently. We tested the G9 with Griot’s foam pads, but you could get the polisher to cut more aggressively with a microfiber pad.

Ergonomics are quite nice, with a removable power cable and a locking trigger that lets you use both hands to manipulate the polisher. The polisher might be manufactured in China, but it’s still designed by Griots Garage in the USA. You won’t find a better polisher for the price.

[Just the Basics] Chemical Guys Torqx

BUY NOW ON AMAZON

VITAL STATS

• Backing plate: 5 inches
• Throw: 8mm
• Weight: 5.1 pounds
• Balance point: 6 inches from leading edge (polisher is 12.5 inches long)
• Noise: 87.1 dB

Chemical Guys has always been a polarizing brand in the detailing space, but the hate has often been unfounded. Everyone starts somewhere in the hobby, and that often means looking for the most affordable products. Affordability sometimes forces compromise. And that’s where the brand’s Torqx polisher surprised us.

Of course, the fact that it doesn’t have a removable power cable means the machine will become a $150 paperweight if (or when) the cable goes bad. Somehow, it’s the lightest polisher we tested, but the ergonomics make zero sense. However, everything else about the Torqx is perfectly acceptable for beginner detailers. Like many polishers on this list, it will achieve 90 percent perfection easily with decently prepped paint.

That gap between 90 and 100 percent is what separates professional detailers from mere weekend warriors like us. Will the average passerby notice the difference? No way.

[Best 3-inch] Griot’s Garage G8

BUY NOW ON AMAZON

VITAL STATS

• Backing plate: 3 inches
• Throw: 8mm
• Weight: 4.25 pounds
• Balance point: 5 inches from leading edge (polisher is 14 inches long)
• Noise: 88 dB

If this is your first foray into polishing, we strongly discourage buying a 3-inch machine to do everything. However, the Griot’s G8 is a great unit if you’re looking for a second polisher to get into those smaller spaces more easily. Griot’s has quite a few compact options, but this short-throw G8 is a great supplementary tool for weekend warriors and professionals.

The short throw, combined with its 3-inch backing plate, makes it super easy to get into small spaces without worrying about the backing plate striking body panels. As you can imagine, the ergonomics are almost identical to the G9 we tested. The short power cord is really the only, well, shortcoming of the G8. That’s why we’d recommend getting Griot’s branded 25-foot quick-connect power cord.

How We Tested Polishers

You might be surprised to hear the polishers were difficult to test. That’s because they’re all incredibly effective at correcting your paint to basically brand-new condition. Like many things in life, the devil’s in the details. As you’ve probably seen with some of our other tests, we seek a healthy balance of subjective and objective metrics to determine which products you should buy.

Test 1: Real-World Performance

Detailers love taping off panels to compare results. And while that instant gratification of the before-and-after result is brilliant, it’s not all that practical when comparing four polishers. But we did it anyway, because we can.

The real meat and potatoes of the test here is how the polisher/pad combo achieved the end result. That’s why we controlled as many variables as possible with our performance test. First and foremost, we called up our local body shop, which graciously let us take an already-discarded trunk panel off their hands to complete the test. We gave the panel a proper wash and decontamination with a clay bar (to remove embedded contaminants) before starting the polishing process.

Once the panel was ready, we masked it off into four sections. Step 1 involved a heavy cut with a foam pad paired with Adam’s Polishes compound. This is where most of the actual correction is happening, leveling off the surface to hide most (but not all) of the visible scratches. We ended up doing four horizontal passes here at very moderate speed and pressure to see how well each can cut. Once that step was complete for each of the polishers, we moved on to polishing, following much the same program with a foam pad and Adam’s polish.

Test 2: Weight and Balance

As you might imagine, polishing any car is a very time-consuming process, especially if you’re new to detailing lark. For context, it took about two and a half hours to compound and polish our Volkswagen GTI, which is a small car. I’d be lying if I said I was a strong man, and that means I couldn’t feel my arms (or hands, for that matter) once I was done.

That’s why we not only weighed each polisher but also measured how close the balance point was to the handle. It might sound complicated, but finding the balance point of any tool is incredibly straightforward. We used the table-edge method, in which you keep pushing the object closer to the edge of the table until it falls off.

Test 3: Noise

We’re a bit over-the-top when it comes to protecting our hearing, but we still think the noise signature of these tools is incredibly important. Even the best polisher in the world deserves a demerit if it sounds like a Vietnam-era helicopter spinning up. Don’t overthink it; lower numbers are better. As you’ll see, we placed the decibel meter next to our work area while we polished the test panel and recorded the maximum reading over two runs. Thankfully, you’ll notice most of these polishers are quieter than expected.

Why Trust Us?

Here at MotorTrend, we know a thing or two because we’ve seen a thing or two—especially when it comes to testing cars. We’ve been testing automobiles for over 75 years, with our first published magazine dropping in 1949. Throughout those 75 years, we’ve tested well over 6,000 cars, refining our process into the methodology we use today.

Seven and a half decades later, we’ve gained a profound understanding of how to test an automobile—and eh… inflation. While cars are our bread and butter, that doesn’t mean product testing has taken a back seat. Our product testing regimen follows the same ethos, targeting just the right dosage of authority and insight. Take this polisher test, for example: You could very well have just surfed around on Amazon and bought the model rated highest.

The difference is that we can categorically tell you which polishers performed the best in our testing.

Car Polisher FAQ

What to Consider

When buying your first polisher, it’s easy to get carried away and buy a million different products and tools. Learn from our mistakes and buy what you need when you need it. Starting out, you’ll just need a basic wash setup: a bucket, car soap, and a proper microfiber drying towel. Sticking to paint correction, you’ll also need a clay bar (or clay towel in our case) to remove embedded contaminants from your paint.

If you pay attention to nothing else, you should absolutely make sure your car is as clean as it can be before you even think about breaking out a polisher.

Dual-Action vs. Rotary

Ask anyone to explain the differences between dual-action (DA) and rotary polishers, and you’ll likely get a different answer every time. Here’s ours:

DA polishers are by far the most beginner-friendly of the bunch. As we mentioned above, these are aptly named as the polisher rotates and oscillates simultaneously. Think of it like Earth’s rotation around the sun: The Earth spins on its own axis while it orbits the sun. This inherent double action drastically reduces the amount of heat that’s transferred to the paint—making it almost impossible to burn through your clearcoat. The only trade-off with DA polishers is that they can’t match the cutting power of a rotary polisher.

It’s no mystery why rotary polishers are much less forgiving than DAs. Their single axis of rotation means they’re infinitely more aggressive than the beginner-friendly DA machines. One of the biggest risks is that they don’t stall on hard edges or if you use too much pressure—they’re just not that sophisticated. Basically, you’ll burn through the paint much more quickly when using improper technique.

Protection

If you didn’t know, polishing your paint isn’t something you should do regularly. With only a finite amount of clearcoat to level out, it’s best practice to correct your paint once and protect your work with a ceramic coating or sealant. Once everything has been sealed up, it becomes doubly important to wash your car properly (minimizing the risk of scratching) and reapply sealants/coatings as they start to wear off.

Confidence

If you’re anything like me, you’re probably a nervous wreck approaching the idea of polishing your paint. Be sure to do your research and take your time when doing this for the first time. Thankfully, these modern tools are exceptionally forgiving, and the only thing you should be worried about is running out of daylight. If you’re a first-time polisher, we highly recommend allotting an entire day to properly clean your car, polish the paint, and protect your work.

To offer some perspective, we corrected a panel with toothpaste, and it turned out most of our coworkers couldn’t see the difference between that and a one-step polish process.
