Although buffing and polishing are both used to improve surface conditions, the materials and steps involved are different. Buffing removes swirl marks and scratches to achieve a smoother finish, but can also strip away surface material if you aren’t careful. Polishing focuses on delivering a high-quality shine on surfaces that are already fairly smooth and isn’t as effective at getting rid of dents, scratches, and other defects.
Buffing and polishing are two common techniques for restoring and maintaining surfaces of all types. Although these terms are sometimes used interchangeably, they refer to different methods that yield distinct results. The main difference between buffing and polishing is that buffing removes scratches, marks, and oxidation while polishing creates a glossy, reflective finish using a smoother abrasive.
In order to avoid costly mistakes and achieve the desired results, it is important to understand the difference between the two techniques. This article examines the differences between buffing and polishing, as well as when to use each one.
Everything You Need to Know About Buffing
Buffing is the process of smoothing or shining a surface using a rotating pad or wheel with an abrasive compound applied. It removes scratches, swirls, and other cosmetic issues from metal, plastic, wood, and even paint to create a smoother finish. For this reason, buffing is often used in automotive detailing to remove oxidation from car paint as well as furniture restoration to rejuvenate the gleam on wooden chairs, tables, and other pieces.
The buffing compound you use will depend on what type of surface you’re working on as well as the degree of abrasion required. For example, black emory is often used for initial smoothing whilegreen orwhite rouge are recommended for final finishing because they create an attractive shine while delivering enough cut to remove minor imperfections and scratches.
Below is a general overview of the steps involved in using abuffing wheel and machine:
Choose the Right Buffing Wheel: Buffing wheels come in different materials and textures, including cotton, felt, muslin, and sisal. Select the appropriate option based on the type of surface you are buffing and the level of abrasion required.
Apply Buffing Compound: Buffing compound is a paste-like substance that helps remove scratches and surface roughness. Apply the compound evenly to the buffing wheel, taking care to avoid oversaturating.
Start Buffing:Turn on the machine and slowly move the rough surface over the wheel. Apply gentle pressure as you move it back and forth and side to side. Make sure to buff evenly over the entire surface to avoid creating grooves or uneven areas.
Check Your Progress: Check your progress from time to time. If you can still see scratches or flaws, continue buffing until they disappear. Depending on the circumstances, you may have to adjust your technique or use a finer buffing compound.
Clean the Surface: Once you have finished buffing, wipe the surface clean with a soft cloth or towel to remove any remaining compound. If you aren't satisfied with the results, repeat the process with a finer compound and a softer wheel to achieve a higher shine.
Using a buffing wheel requires some practice and patience, but with the right tools and techniques, it can produce excellent results. Always wear appropriate safety equipment, such as gloves and eye protection, to prevent injury.
Everything You Need to Know About Polishing
Polishing is the process of smoothing a surface to a high shine using a soft wheel or pad and a polishing compound. Unlike buffing, which is mainly focused on removing scratches and other blemishes, its goal is to produce a mirror-like finish. Common uses include creating a mirror-like finish on metal workpieces or jewelry and restoring luster and gloss to higher-end furniture.
Polishing compounds come in different types and are chosen depending on the level of abrasion required and the type of surface being polished. For example, brown tripoli is a common choice for softer metals while blue polishing compound is recommended for plastics and synthetic materials.

Here are the steps for polishing a surface using a polishing wheel and machine:
Choose a Polishing Wheel:Like buffing wheels, polishing wheels come in different materials, such as cotton, felt, and foam. Your selection should be appropriate for the type of surface being worked on.
Apply Polishing Compound: Apply the compound, which is a liquid or paste-like substance, evenly to the polishing wheel before attaching it to the machine. Make sure the wheel is secure and the machine is stable.
Start Polishing: Turn on the machine and slowly glide the surface over the polishing wheel. Apply gentle pressure as you move the surface back and forth and side to side.
Check Results: Stop polishing periodically and check your progress. If you can still see defects, continue polishing until they are removed. If necessary, switch to a finer polishing compound.
Clean the Workpiece: Once you’re done, clean the surface thoroughly to remove any smeared or caked-on residue. If you aren’t satisfied with the level of shine, repeat the process with fresh polishing compound until you achieve the desired result.
Like buffing, it can take a while to get the hang of using polishing wheels and compounds, but once you’ve got the hang of it, the results can be outstanding. As usual, always wear appropriate safety equipment at all stages of the polishing process.
Buffing vs. Polishing
The main difference between buffing and polishing is the level of abrasion used. Buffing is more aggressive and uses an abrasive compound to clear away marks and scratches while polishing is less intense and uses a smoother abrasive material to create a shiny, reflective surface. The advantages and disadvantages of each technique depend on what you’re working on and the desired results.
Buffing is ideal for surfaces that have visible scratches or swirl marks, as it smooths away these types of flaws or irregularities. However, it can leave marks or distortions if too much pressure is applied. Buffing can also remove a layer of surface material, which may not be desirable for some applications.
Polishing, on the other hand, is recommended for workpieces that are already fairly smooth and just require a glossy finish. This is because polishing is less aggressive and does not remove any surface layers, making it less likely to cause damage. However, it may not be as effective when you’re dealing with deeper scratches or dents.
When deciding whether to use buffing or polishing, it is important to consider the type of surface being worked on and the desired outcome. For example, if a car has scratches and swirl marks on the paint, buffing may be the best option to restore the shine. If a piece of jewelry needs a glossy finish, polishing can create the smooth, shiny surface you’re looking for. Ultimately, the choice between the two options depends on the specific needs of the project and the level of abrasion required to achieve the desired results.
Compound Quality Can Make All The Difference
Both buffing and polishing have advantages and disadvantages depending on the material you’re working with, its pretreatment condition, and whether you want a smooth or high-gloss finish. The quality of the buffing or polishing compound can also have an impact on how happy you are with the final result.
