Stainless steel is one of the most popular materials used in modern kitchens, appliances, and even outdoor equipment due to its durability, sleek appearance, and ease of maintenance. However, over time, it can develop unsightly scratches and scuffs that detract from its pristine look. One common household product that people turn to is Bar Keepers Friend. Known for its effectiveness in cleaning a variety of surfaces, it’s often recommended when tackling stubborn stains—but can Bar Keepers Friend remove scratches from stainless steel?
In this comprehensive article, we’ll explore the answer to that question in detail. We’ll discuss what causes scratches on stainless steel, how Bar Keepers Friend works, its effectiveness on different types of scratches, proper application techniques, and alternatives if it doesn’t deliver the results you’re hoping for. Whether you’re dealing with cookware, sinks, or appliances, this guide will provide you with all the information you need.
Understanding Stainless Steel and Its Susceptibility to Scratches
Before diving into the scrubbing action, it’s important to understand stainless steel and why it gets scratched in the first place.
Stainless steel derives its name from its corrosion-resistant properties, not its scratch resistance. It is made by combining iron with at least 10.5% chromium and other alloys like nickel and molybdenum. While resistant to rust and staining, it is not immune to physical damage such as scratches.
Types of Scratches on Stainless Steel
Scratches on stainless steel can be categorized into two main types:
- Surface-level scratches: These are fine, thin lines that don’t penetrate deeply into the steel. They often come from abrasive cleaning pads, improper wiping methods, or the use of harsh detergents.
- Deep scratches: These are more pronounced and penetrate into the surface layer. They can be caused by knives, abrasive materials, or impact from hard objects.
The effectiveness of any cleaning method, including the use of Bar Keepers Friend, largely depends on the severity of the scratch.
What Is Bar Keepers Friend?
Bar Keepers Friend (BKF) is a powdered cleanser that has been trusted for decades in kitchens and homes. Available in both powder and liquid form, it’s formulated with a blend of ingredients designed for cleaning and polishing without harsh abrasion.
Key Ingredients and Their Cleaning Properties
Understanding the ingredients in BKF helps clarify its effectiveness:
- Oxalic acid: The primary cleaning agent in BKF, oxalic acid is excellent for removing rust, lime scale, and mineral deposits. For light scratches, it can help restore the shine by breaking down the oxidized materials on the surface.
- Sodium lauryl sulfate: A mild surfactant that helps lift away oils and greasy residues from surfaces.
- Silica and abrasive agents: These offer scrubbing action to lift stains but are relatively gentle compared to coarser cleansers like steel wool or pumice stone.
The inclusion of oxalic acid makes BKF especially effective for tackling metal surfaces, but its ability to polish and remove scratches depends on the scratch depth and your technique.
Does Bar Keepers Friend Actually Remove Scratches from Stainless Steel?
Now, let’s address the main question: Can Bar Keepers Friend remove scratches from stainless steel?
The short but nuanced answer is: Yes, Bar Keepers Friend can help reduce the appearance of light scratches and scuffs on stainless steel surfaces, but it has limitations when it comes to deep, ingrained scratches.
Let’s explore how it works at the microscopic level and the expectations you should set based on scratch severity.
How BKF Affects Surface-Level Scratches
With surface-level scratches, BKF helps reduce their appearance by:
- Uniformly polishing the tops of the metal, which lessens the contrast between the scratched and pristine areas.
- Removing oxidation and mineral deposits that accumulate in the scratched grooves, thereby improving the overall visual clarity of the surface.
- Using the mild abrasive particles in the powder to wear down the sharp edges of the scratch slightly.
The result is usually a visibly smoother surface where the scratch becomes much less noticeable or even disappears entirely.
Its Limitations with Deeper Scratches
When dealing with deep scratches, BKF may improve the shine of the immediate area, but it won’t eliminate the scratch. Deep grooves often involve physical deformation of the steel surface beyond what a chemical cleaner can handle. For these cases, mechanical sanding or professional refinishing may be required.
Step-by-Step Guide to Using Bar Keepers Friend on Stainless Steel Scratches
To get the best results from BKF when tackling surface scratches, follow these steps:
- Clean the surface thoroughly. Remove grease, oil, or debris using warm water and dish soap. Dry with a soft cloth.
- Make a paste. Mix the Bar Keepers Friend powder with water to create a thick, toothpaste-like consistency.
- Test on a small area. Apply a small amount to an inconspicuous part of the steel to check for any adverse reactions or discoloration.
- Apply in the direction of the grain. Always rub along the grain of the stainless steel—not circularly or against the grain—using a soft sponge or cloth. This minimizes the risk of creating new scratches.
- Work in small sections at a time. Gentle but firm pressure works best. Continue rubbing for about 30 seconds to a minute per section.
- Rinse and dry thoroughly. Use clean water to remove all residue. Then dry with a soft, lint-free towel to avoid water spots.
- Inspect the results. Repeat the process if needed, especially for tougher spots or persistent blemishes.
Remember, for best results:
- Use non-abrasive cloths or sponges to avoid further scratches.
- Avoid using steel wool or wire brushes, which can leave behind metal particles and cause rusting.
- Never mix BKF with bleach or ammonia; it can create harmful fumes.
Realistic Expectations: What Bar Keepers Friend Can and Can’t Do
The effectiveness of BKF on scratches depends heavily on a few key factors:
1. Depth of the Scratches
As discussed, surface-level scratches can often be improved or fully removed by BKF’s polishing action. However, deep indentations will not disappear, only look shinier.
2. Frequency of Use
Using Bar Keepers Friend consistently can slow the appearance of new scratches and maintain a polished look, but it won’t build up metal or fill in grooves.
3. Cleaning Technique
Using the right technique—such as following the grain and avoiding applying excessive pressure—is crucial for avoiding more damage and achieving an even finish.
4. Quality of Stainless Steel
Cheaper stainless steel, such as lower-grade 304 or 430 varieties, is often thinner and more prone to visible scratching than higher-grade steel like 316, which is more commonly used for marine or industrial applications.
Alternatives to Bar Keepers Friend for Removing Scratches
If Bar Keepers Friend isn’t suitable for deeper scratches or larger jobs, there are alternative options to consider:
1. Stainless Steel Scratch Removers and Polishes
Several commercial products like Never Dull, Reuben’s Polish, or 3M Stainless Steel Cleaner & Polish are formulated specifically for polishing and protecting stainless steel from scratches. These are more specialized and may provide different results.
2. Mechanical Sanding
For deep scratches, especially on sinks or metal furniture, you can use fine-grade sandpaper (starting from 120 grit up to 2000 grit) in combination with lubricants or oils. This method involves sanding along the grain and is best for more advanced DIYers.
3. Metal Buffing and Professional Refinishing
If the scratches are widespread or the metal is valuable (such as a high-end appliance or custom stainless steel countertop), hiring a professional to buff and refinish it may be the most effective route.
Additional Care Tips for Maintaining Stainless Steel
Once you’ve restored your stainless steel surface, maintaining it properly is the key to keeping it looking like new for as long as possible.
Daily Cleaning Practices
- Wipe down stainless steel daily with a mild soap or stainless steel cleaner.
- Use microfiber cloths to reduce streaks and scratching.
- Always follow the grain when cleaning or using any abrasive pad, no matter how fine.
Safe Storage and Handling
- Store pots, pans, and utensils in ways that prevent them from scratching one another.
- Avoid placing sharp or hard-edged items directly onto stainless steel surfaces.
- Use protective mats or racks when drying dishes and cookware.
Use of Protective Coatings
Some users apply a thin layer of food-safe mineral oil or specialized stainless steel protectants to enhance shine and offer a protective barrier against future scratches and fingerprints.
Case Studies and Real-World Applications
Let’s look at a few common real-world scenarios where people have used Bar Keepers Friend on stainless steel:
Case 1: Stainless Steel Sink Restoration
A homeowner with a moderately scratched sink used BKF paste alongside a soft cloth over the course of a weekend. After several rounds of careful polishing, the sink looked significantly better, with surface scratches and water spots minimized.
Case 2: Appliance Damage From Improper Cleaning Tools
A dishwasher owner noticed long, fine scratches caused by a stainless steel cleaner that contained harsh abrasive pads. By switching to BKF and cleaning only along the grain, they managed to restore most of the panel’s appearance without further damage.
Case 3: Deep Scratches on a Professional Stove
A chef accidentally scratched the surface of a commercial-quality stainless steel cooktop with a metal spatula. Despite several attempts with Bar Keepers Friend and other abrasives, the scratch remained—illustrating BKF’s limitations with deep surface damage.
Conclusion: Is Bar Keepers Friend Worth It for Scratches?
In conclusion, Bar Keepers Friend can effectively reduce or remove light scratches and minor scuffs on stainless steel surfaces by lifting oxidation and polishing the top layer. However, it is not a miracle solution for deep scratches or extensive surface damage.
Used with the proper technique and the right expectations in mind, BKF can be a powerful part of your stainless steel care routine. For more severe damage, professional polishing techniques or alternative products may be more appropriate. The best approach is a combination of regular maintenance, gentle cleaning, and using trusted products like Bar Keepers Friend to keep your stainless steel looking pristine.
By taking a proactive cleaning and care strategy, you can preserve the lustrous finish of your stainless steel for years to come. Whether you’re a home cook or a professional chef, a little care goes a long way in protecting your investment and keeping your metal looking like new.

Can Bar Keepers Friend remove scratches from stainless steel?
Yes, Bar Keepers Friend can help reduce the appearance of light scratches on stainless steel surfaces. Its formula contains oxalic acid, which is effective at dissolving mineral deposits, rust stains, and other surface imperfections that contribute to dullness and blemishes. When applied correctly with a soft cloth and used in the direction of the grain, it can polish the metal and help make superficial scratches less noticeable.
However, it’s important to note that Bar Keepers Friend does not actually “remove” deep scratches in the mechanical sense. Instead, it works by cleaning and polishing the surface, which can smooth out minor flaws and refinish the top layer of the steel. For deeper scratches that have altered the metal’s integrity, more aggressive methods such as sanding with fine-grit abrasives followed by polishing may be necessary to fully restore the surface.
Is Bar Keepers Friend safe for stainless steel?
Bar Keepers Friend is generally safe for use on stainless steel when used as directed. It is specifically formulated for non-porous surfaces and does not contain harsh abrasives that could damage the thin, polished layer of the steel. However, it’s always a good idea to test it on a small, inconspicuous area before applying it more broadly, especially if the steel has a brushed or matte finish, which may react differently to chemical cleaners.
Prolonged or overly aggressive use of Bar Keepers Friend can, over time, wear down the protective layer of stainless steel, particularly on lower-quality or thinner alloys. To avoid harm, avoid scrubbing too hard and rinse the surface thoroughly after application. Additionally, it should not be used on aluminum or non-stick surfaces, so confirming the material you’re cleaning is crucial before proceeding.
How should I apply Bar Keepers Friend to fix scratches on stainless steel?
To properly apply Bar Keepers Friend on stainless steel, start by moistening a soft cloth or sponge and sprinkling a small amount of the powder onto the wet surface. Apply the mixture to the scratched area in the direction of the grain, using gentle pressure and a circular or back-and-forth motion depending on the scratch depth. It’s important to follow the steel’s natural grain pattern to avoid causing further visible damage.
After scrubbing for a few minutes, wash away the paste thoroughly with warm, soapy water and dry the area with a clean microfiber cloth. Inspect the area to see if the scratch has diminished. If necessary, repeat the process, but avoid over-scrubbing. Afterward, apply a stainless steel polish or food-safe mineral oil to help restore shine and provide an added layer of protection against future scratches and stains.
Can I use Bar Keepers Friend on appliances with a stainless steel finish?
Yes, Bar Keepers Friend can be used safely on stainless steel appliances provided the finish is not coated with protective elements like lacquers or sealants that might react to the product. Many modern refrigerators, ovens, and dishwashers feature a stainless steel finish that can benefit from occasional use of Bar Keepers Friend, especially when dealing with water spots, minor scratches, or soap scum buildup.
Before applying it to a large area, always check the manufacturer’s instructions or look for warnings about chemical or acidic cleaners. If the finish is sealed or painted, Bar Keepers Friend may strip away the protective layer and cause discoloration. Once confirmed as safe, use a soft cloth and avoid abrasive tools like steel wool, which could worsen the appearance of scratches or leave behind unwanted lint and debris.
Will using Bar Keepers Friend scratch the stainless steel surface?
Bar Keepers Friend is not abrasive in the way that products containing grit or sanding agents are, but its active ingredient—oxalic acid—can leave swirl marks or marring if used improperly or aggressively. This is especially true on brushed stainless steel, where applying pressure against the grain can cause the finish to appear inconsistent or more damaged than before the treatment.
To avoid any induced scratching or surface marring, always follow the grain when scrubbing and use minimal pressure. A soft microfiber cloth or sponge will help ensure effective cleaning without leaving unwanted marks. After polishing, rinse the surface thoroughly and dry it gently to preserve the aesthetics and integrity of the stainless steel finish.
What causes scratches on stainless steel, and can they be prevented?
Scratches on stainless steel are often caused by abrasive cleaning tools like steel wool, harsh scrub brushes, coarse particles such as sand or dirt, or even using improper microfiber cloths that trap grit. Everyday use, improper stacking of pans or tools, and sliding objects across flat surfaces can all lead to visible marks and scratches. Although stainless steel is durable, the protective chromium oxide layer can still be marred by repeated contact with hard objects.
While it’s nearly impossible to prevent all scratches, several strategies can minimize their occurrence. Use soft cloths and non-abrasive cleaning tools, and avoid scrubbing against the grain. Always clean the surface before wiping it down to remove particulates that may scratch it. Proper maintenance with mild soaps and periodic use of stainless steel protectants can help reduce the visibility of scratches and maintain the pristine appearance of the surface over time.
Are there alternatives to Bar Keepers Friend for removing scratches from stainless steel?
Yes, there are several alternatives to Bar Keepers Friend that can also help in reducing scratches and restoring the appearance of stainless steel. Products such as Cameo Aluminum & Stainless Steel Cleaner, Revere Copper and Stainless Steel Cleaner, and even natural remedies like vinegar and baking soda can be effective for lighter marks. Some users also prefer commercial stainless steel polishes or specialty scratch removers designed for the metal, which may offer similar or improved results depending on the severity of the scratch.
In addition to chemical cleaners, mechanical approaches like using fine steel wool (Grade 0000) with oil or metal polish compounds such as Wenol or Flitz can help buff out minor imperfections. For deeper scratches, wet sanding with extra-fine grit sandpaper (e.g., 1500-2000 grit) followed by polishing may be required. Each method has its pros and cons, so it’s often helpful to test a small area or combine techniques to achieve the best finish without compromising the steel’s surface.
