Aluminum wheels are a popular choice for many vehicles due to their lightweight, durable properties, and stylish appearance. However, they can be a honeypot for dirt, grime, and brake dust adhesion over time, dulling their shine and affecting their performance.

I will provide you with a step-by-step guide on performing aluminum wheel cleaning effectively, whether they are polished, oxidized, or coated with a clear coat.

How To Clean Aluminum Wheels

Cleaning aluminum wheels can help keep them looking shiny and new, but it’s important to use the right techniques and products to avoid damaging the metal. Below is a step-by-step guide on the cleaning process.

Step 1: Preparation

Before cleaning your aluminum wheels, ensure they are cool to the touch and out of direct sunlight. It’s also a good idea to wear protective gloves to prevent skin irritation or chemical burns.

Step 2: Rinse the wheels

Use a hose or pressure washer to rinse any loose dirt or debris from the cool wheels. This will make it easier to clean them properly.

Step 3: Apply detergent or wheel cleaner

Mix a mild detergent with water in a bucket, or use a specialized aluminum wheel cleaner according to the manufacturer’s instructions. Apply the cleaner to the wheels using a sponge or a soft brush, covering all surfaces evenly.

Step 4: Scrub the wheels

Using the brush or sponge, gently scrub the wheels to eliminate any dirt, grime, or brake dust build-up. Pay extra attention to the nooks and crannies around the spokes and lug nuts.

Step 5: Rinse thoroughly

Use a hose or pressure washer to thoroughly rinse off the wheels, removing all traces of detergent or cleaner. Rinse from top to bottom so that any dirt or debris on the lower part of the wheels doesn’t splash back onto the clean areas.

Step 6: Dry the wheels

Use a microfiber towel or chamois to dry the wheels thoroughly. This will help prevent water spots or streaks from forming.

Bonus Step: Make it look like new by applying polish or wax

Let’s say you want to give your aluminum wheels extra shine and protection. In this case, you can use a wheel polish or wax according to the manufacturer’s instructions.

This will also help prevent corrosive brake dust and other contaminants from sticking to the surface of the wheels. Here is what you need to do.

Step 1: Choose a polishing product specifically designed for aluminum wheels and apply it evenly using a foam applicator pad or soft cloth in circular motions.
Step 2: Buff the wheel to a shine with a clean microfiber cloth or buffing pad, removing any excess cleaning product until the surface is smooth and shiny. My tip is to always use a fresh cloth to buff a new polish to prevent getting old polish back on the wheel.
Step 3: Repeat the buffing process as necessary for optimal results.

For Polished Aluminum Wheels

Cleaning polished aluminum wheels is a slightly different cleaning technique that can help avoid damaging the wheel finish. Here is a tried-and-true method to get the best results.

Step 1: Prepare the wheels

Park your vehicle in a shaded area away from direct sunlight.

This is because a sunkissed place with high temperature will probably dry out the cleaner on the wheel before being washed off. And when it sticks to the surface, you have to rub it hard to remove, increasing the risk of scratching the polished finish.

Remove any center caps or hubcaps and set them aside in a safe location.

Step 2: Rinse the wheels

Use a hose or pressure washer to rinse off any loose dirt and debris from the wheels.

Step 3: Apply the cleaner

Apply a generous amount of specialized cleaners on wheels. Ensure the cleaner is specifically designed on polished aluminum wheels to avoid damaging the finish.

Step 4: Let the cleaner sit

Allow the cleaner to sit on the wheels for a couple of minutes to dissolve dirt, grime, and brake dust buildup.

Step 5: Scrub the wheels

Rub the wheels’ surface with a sponge or a soft-bristled brush, focusing on any areas with heavy dirt or grime buildup. Remember to exert a light force to not scratch the polished surface.

Step 6: Rinse thoroughly

Rinse the wheels thoroughly with clean water, removing all traces of the cleaner.

Step 7: Dry the wheels

Use a dry microfiber cloth or chamois to dry the wheels completely. Be sure to path dry any water spots or streaks.

Step 8: Apply a protective coating

Use a specialized aluminum wheel wax or sealant to help safeguard the polished surface from future damage.

For Oxidized Aluminum Wheels

Aluminum wheels can oxidize over time due to exposure to air, moisture, and other environmental factors. Oxidation layer can make the wheels look dull, discolored, and even rough to the touch. Apply the following instructions if you want to get rid of these annoying stains.

Step 1: Mix the vinegar solution

Mix equal parts of white vinegar and water in a bucket or spray bottle. This will create a mild vinegar cleaning solution safe for cleaning aluminum alloy wheels.

Step 2: Apply the solution

Spray or apply the vinegar solution to the oxidized aluminum wheels. Use a sponge or soft-bristled brush to work the cleaning agent into the wheels, paying extra attention to the areas that are heavily oxidized.

Step 3: Allow this aluminum wheel cleaner solution to sit

Let the vinegar solution sit on the wheels for 7-10 minutes. This will give the mixture enough time to dissolve and remove the oxidized layer.

Step 4: Scrub the wheels

Scrub the wheels thoroughly using the brush or sponge to get rid of any remaining dirt or debris. Tread with caution and steer clear from using abrasive cleaners or rough brushes that can scratch the surface of the metal.

Step 5: Rinse thoroughly

Use a hose or pressure washer to thoroughly rinse off the wheels, eliminating all traces of the wheel cleaning solution. Notice to always rinse from top to bottom to not dirty the clean areas again.

Step 6: Dry the wheels

Use a microfiber towel or chamois to dry the wheels thoroughly. Or else, you will see water spots or streaks forming afterwards.

How To Remove Clear Coat On Aluminum Wheels

Erasing the clear coat from cast aluminum wheels can be done using various methods, depending on the type and condition of the clear coat. Here is a step-by-step guide on removing clear-coated aluminum wheels using a chemical stripper.

Step 1: Preparation

Before starting, make sure you are in a well-ventilated area or work outdoors. Wear protective gloves, eyewear, and a respirator or mask to avoid breathing in fumes or getting the stripper on your skin or eyes.

Also, protect the surrounding area from the stripper and cover any parts of the wheel that you don’t want to strip.

Step 2: Apply the chemical stripper

Apply a chemical paint stripper for metal polishing surfaces to the aluminum wheel. Follow the manufacturer’s instructions on how to use the product. Brush on the stripper in a thick, even layer, covering the entire wheel surface.

Step 3: Allow the stripper to sit

Allow the stripper to work its magic on the wheel for the amount of time specified by the manufacturer. This is for the stripper to dissolve the clear coat.

Step 4: Scrape off the clear coat

Use a plastic scraper or putty knife to scrape off the clear coat from the aluminum wheel. Stay away from metal scrapers or knives that can scratch the surface of the wheel.

Step 5: Sand the wheel

Utilize steel wool or fine-grit sandpaper to sand the aluminum wheel thoroughly. Sand in a circular motion, working in small areas at a time. This will help erase any remaining clear coat and smooth out the surface of the wheel.

Step 6: Rinse thoroughly

Rinse the wheel thoroughly with a stream of water to wash off any remaining stripper or debris.

Step 7: Apply a protective coating

To protect your aluminum wheels from further damage, you can apply a protective coating, such as wheel wax or sealant, following the manufacturer’s instructions.
