Tested: The Best Car Buffers for 2023

Ergonomic and powerful, Adam's Swirl Killer vanquished its swirly enemies with ease.

Shine on, you crazy diamond! The TORQX—while quite vibrate-y—did an excellent job at cleaning up our junker.

The compact Batoca foam pad and Meguiar's Cleaner Wax cleaned our junkyard example with ease.

Nothing but shine. Avid Power is an excellent dual-action starter package.

Preparation

First, wash your vehicle thoroughly and rinse. Next, you'll want to use a clay bar to remove environmental contaminants such as brake dust, sap, and water spots. Clay bars require lubricant, so be sure to have a quick-detailing product on hand to spray while you clay-bar your car.

Then, working one small section at a time, spray and rub the clay bar over the area, regularly folding the clay bar over to trap the lifted contaminants into the folds. This step is crucial. If you don't clay-bar your vehicle, you run the risk of buffing those contaminants INTO your paint.

Technique

Polishing your car is a dance between the tool and the user, and technique is essential to master. With a dual-action polisher, a novice can get this down quite quickly—but it takes practice and a gentle-but-firm touch.

Treating deep scratches in your car’s finish with medium- to heavy-duty polishing compounds works best with a high-speed polishing wheel and should be left to experienced technicians. But ultrafine finishing polishes can be used with a dual-action buffer to remove light scratches.

To start, put a small amount of product onto a moistened pad, start the machine, and begin polishing in an overlapping zigzag pattern, keeping the pad even against the paint surface. Slowly work a small section at a time, experimenting with gentle to moderate pressure. Reapply the product as needed and remove excess polish with a clean microfiber cloth. The process is the same for applying a thin haze of car wax afterward, but you don’t need to put as much pressure on the machine while you work.

Here at the Gear Team HQ, we're hurtin' for cars that need a shine. So rather than tidying up an already-stellar paint job with one of Car and Driver's brand-new review/demo models, we opted for the "wow!" factor and pulled a trashed hood off a junked '90s Chevy Caprice we found at Regal U-Pull It in Howell, Michigan.

We prepared the hood by washing and clay-barring its surface to remove contaminants. We then partitioned the hood into six squares using painter's blue tape, one for each buffer and one as a control square, to gauge our buff jobs against the hood's original dingy appearance. We designed this test to evaluate the comfort and effectiveness of each buffer using Meguiar's Cleaner Wax, recommended to us by our staff detailing czar, Mike Sutton.

During the hood challenge, we took detailed notes on the comfort and security of each buffer's handholds, any fatigue we felt, and its ease of use. Additionally, we used our decibel reader from a two-foot distance, recording the average decibel output of the unit over 15 seconds. Afterward, we visually inspected the results and took after shots.

For durability, tester Collin Morgan dropped each running car buffer from chest height, recording any damage. We also tested each buffer's safety features by pressing down on a scale to gauge pressure, recording if each unit had a fail-safe and, if so, what weight threshold activated it.

Lastly, we ran the two battery-powered units we tested through a battery-life test. Turning each unit to its lowest setting, we let them run, thinking it would be a short while. Instead, testers Collin Morgan and Gannon Burgett drove home and had dinner, all with dancing buffers in tow, eventually taking note of their time of death. The battery life of each is noted above in its spec sheet.

It is important to note that the final result you achieve from any car buffer or polisher is influenced by many factors: the buffer's properties (motor, power, etc.), the user's pressure and technique, the pad quality and durability, and the type of buffing agent used.

What is a car buffer?

A car buffer is a power tool (either plug-in or battery-powered) that applies polishing compounds or wax to a vehicle's paint surface. It helps remove light scratches, swirl marks, and other imperfections, resulting in a glossy, mirrorlike finish.

What are the different types of car buffers?

There are two main types: dual-action buffers and rotary polishing wheels. Dual-action buffers spin and oscillate in random patterns, while rotary polishing tools spin at a constant speed. We recommend going with a dual-action buffer, as the polishing pattern reduces the risk of damaging the paint if you accidentally press down too hard or hold the buffer in one spot for too long. We stuck to dual-action and orbital buffers for this test, considering they're the more beginner-friendly tools.

How do I choose the right car buffer for my needs?

Consider your experience level, budget, and desired results. We recommend using a dual-action buffer for everything unless you have a ton of professional experience. Dual-action buffers are beginner-friendly and have a lower risk of paint damage, making them the ideal option for most consumers.

What are the recommended speeds for using a car buffer?

Speed settings vary depending on the type of buffer, pad, and compound used. For dual-action buffers, a range of 2000–6000 opm (oscillations per minute) is common for most applications.

What type of pads should I use with my car buffer?

Car buffer pads are typically made of foam, microfiber, or wool. Foam pads come in various levels of aggressiveness, from cutting to polishing and finishing. Microfiber pads are versatile and can be used for cutting, polishing, and finishing, while wool pads are generally more aggressive and used for heavy cutting and compounding.
