Why Trust Us
All of our reviews are based on market research, expert input, and practical experience with each product we include. This way, we offer genuine, accurate guides to help you find the best picks.
Benefits of Metal Polish
- Aesthetics. The simple and straightforward answer to why you need metal polish is that it makes your car look good. All the chrome and metal parts on your car need to be taken care of as well. Metal polish lets you do just that.
- Maintenance. As part of your car maintenance routine, you should include a regular polishing of all chrome and metal parts. That not only helps them (and your car) look their best but will also aid in keeping everything in good condition.
- Restoration. If your car’s details are already looking a little worn, fear not. Certain types of metal polish have restorative properties that will help buff out the signs of wear on metal parts, helping them to look new again.
- Resale value. This one almost goes without saying, but keeping your car in excellent condition overall will retain the maximum resale value for as long as possible. That will come in handy when you’re looking to trade up down the line.
Types of Metal Polish
Restorative metal polishes contain higher levels of abrasives, which help to restore the surface of the metal you’re polishing. Best for worn, rusted, or pitted metal and chrome details, this type of metal polish is a real life-saver for metal parts that have lost their lustre.
A milder type of metal polish, polishing products tend to require a bit more elbow grease to use. They are, however, mild enough to use regularly without damaging the surface of whatever metal parts you’re using them on. They won’t restore metal parts, but they are ideal for keeping the lustre alive and well.

Metal Polish Pricing
- Under $10: You’ll find a lot of basic metal polishes at this price point, some of which will be decent to good quality, and others which will be of poor quality. In this price range, it’s important to be on the lookout for the quality of the formulation, as bad additives can be damaging.
- $10-$20: In the mid-range, you’ll find a number of great products that will take care of your metal polishing needs. There are still some differences between brands in terms of quality of the formulation, but most will get the job done.
- Over $20: If you’re looking for the best of the best, this price range will deliver. Quality will be high, eco-friendliness is often considered, and toxic additives are left to the wayside. That being said, a couple of products can be overpriced for what they are, so watch out for hype.
The strength of the polish corresponds to the number of abrasives in the formulation. Higher grits are better for restoring rusted and pitted metal parts, whereas lower grit is ideal for upkeep. You can also switch between the two as your needs change, starting off with the higher abrasive polish to restore your metal parts and then switching to the milder formulation to keep things lustreful.
A major point to keep in mind is the formulation itself. Generally, metal polishes come in one of two forms: as a viscous, wax-like product or a runny, watery one. The thicker, paste-like formulation is easier to use, as it doesn’t drip down or runoff, helping to get the product right where you need it.
A number of products have formulations that will offer some degree of long-term protection. Metal polishes do this by building up a layer over several applications, which works to block grime and dirt, and may help prevent pitting. Through this, the metal will also maintain its shine over long periods of time.
- Eco-Friendly: All metal polishes are chemical products, but some contain more harmful ingredients than others. If eco-friendliness is an important factor for you, watch out for petroleum-based products, which both smell strangely and aren’t great for the environment.
- Multiple Application: Some metal polishes can be used on other surfaces as well. These can include porcelain, wheels, and even silver. If a multi-use product appeals to you, check the label for all recommended use cases.
- Packaging Size: If you’ve got lots of metal to polish, you’ll want a bigger bottle or tub of product. But keep in mind that some polishes tend to wear down once opened, so don’t buy too much at once.
- Quality: Metal polishes contain abrasives that could potentially damage your vehicle if they’re too coarse. Watch out for poor quality metal polishes, which could end up doing more harm than good to your vehicle.
Best Metal Polish Reviews & Recommendations 2019
Best Overall: Chemical Guys Heavy Metal Polish Restorer
Suitable for a number of different metal surfaces, this heavy-duty metal polish is our top pick thanks to its all-rounder status. It’s ideal for cleaning and restoring a number of different metal surfaces, including chrome bumpers, stainless steel exhaust tips, and aluminum trim. Light rust stains and oxidation are removed with one application, even from billet wheels. Also suitable for diamond plate metal work, this metal polish works even better when topped with a protectant to seal in the shine.
Ideal for use with polishing pads, we’ve seen this product do great work on restoring worn down metal trim and chrome finishings. If you’ve got an older car with a chrome bumper, this will do wonders for its lustre, even if pitting has already set in. The heavy-duty nature of this product does a great job of restoring a number of metal finishings on your vehicle.
The one downside is that it’s a little bit on the pricey side, which makes it a little less appealing for those sticking to a tight budget. That being said, you get a great product with the investment, and the bottle should last you a while, so keep that in mind when deciding on a metal polish.
Best Value: Mothers Mag & Aluminum Polish
A gentler alternative to high grit polishes, this Mothers Mag & Aluminum Polish is suitable for regular use, making it ideal for all your metal polishing upkeep purposes. Regular use protects your vehicle’s aluminum finishing and other metal trim from fading, dirt, and grime. The easy-to-apply formula works best when applied with a clean cloth and a little elbow grease. As a multi-use product, this metal polish can be used on stainless steel and many other metals outside of your car.
Although the formula is on the less abrasive side, you can still use this product on mild oxidation to clean up the metal and restore lustre. It also works on headlights that have been scuffed or fogged up, although we recommend caution in this approach to avoid damage. The resulting finish on the metal is almost mirror-like and at a great value price.
If you’re looking for something to polish up your chrome, this is not the right product for you, as it isn’t made for this purpose. That being said, it works exceptionally well on a number of other metals and metal alloys, so double-check the type of finish you have.
Honorable Mention: Simichrome All Metal Polish
The choice of many professional car detailers, Simichrome All Metal Polish does a beautiful job at removing surface rust from chrome, polishing up aluminum to look like new, and sprucing up delicate silver pieces without leaving scratches, scuffs, or any other abrasive marks. The paste-like formula makes the product really easy to use, producing a rich, brilliant shine on any uncoated, non-ferrous metal surface.
The formulation is also designed to leave an invisible, protective coating that prevents further tarnishing, protecting the shine and lustre for longer; that also saves you time and energy down the line. Since it’s suitable for almost any metal surface, one tube will go a long way of taking care of your metal polishing needs.
The big downside with this polishing product is the ingredient list. As a petroleum-based product, it does an excellent job at polishing up metal, but it does so at a cost to the environment and maybe even your health, as prolonged contact with the product can be harmful. Keeping that in mind, if you’re cautious when using this product, you should have no problems.
- Make sure you wash your car properly before polishing any metal details. This will ensure a superb finished lustre, as well as protection from damage, as dirt and grime can cause harm to the finish.
- Paste-like metal polish formulations are easiest to use since you can easily control the movement of the product.
- Apply metal polishing in small circular strokes for an even finish, and always use a clean cloth or applicator to avoid damage.
- For polishing first-timers, remember that a little product goes a long way. Also, keep in mind that the final results depend a lot on both your elbow grease and the product itself, so keep at it.
- Rusting, pitting, and other damage can be restored using a heavy duty polishing solution. Apply it with a power tool for best results, and seal it up with a protecting polish when you’re done.
Q: What’s the best way to polish chrome details?
A: The first step in any polishing routine should always be a thorough wash and dry. This will remove any built-up dirt and grime, making space for the metal polish to do its work. Next up, apply your choice of metal polish to a microfiber cloth or sponge. With a little elbow grease, work in the product until the level of lustre you desire is achieved. That’s it!
Q: Can I use metal polish to restore the shine of a chrome exhaust pipe?
A: The short answer is yes! Since a chrome exhaust is a metal detail just like any other, you can use the same steps we detailed above to restore the pipe’s lustre. Keep in mind that exhaust pipes do get hot, so make sure that it’s cool to the touch before beginning the wash, dry, and polish routine to avoid injury and unflattering results.
Q: How often can I polish my metal details?
A: We recommend about twice a year, but you can do it a little more frequently, provided you’re using a high-quality, mild metal polish. Anything with a high grit can damage the finish with repeated use.
Q: Can I use a polishing tool to shine up chrome and aluminum details?
A: You can use any application method you desire to polish up chrome and aluminum details, although power tools are best used in extreme cases to restore the finish using heavy-duty polishes. If you’re wanting to do some upkeep polishing, we recommend skipping the power tools or being extra gentle while using them to avoid over-polishing.
Our top pick is the Chemical Guys Heavy Metal Polish Restorer. It does an excellent job at restoring rusted and worn metal components without too much of a hassle.
