Removing Chrome from Wheels(aluminum 7075 vs 6061 Martin)

Chrome-plated wheels are a popular choice among car enthusiasts, as they add a sleek and shiny appearance to vehicles. However, over time, the chrome coating may become scratched, damaged, or you may simply wish to change the look of your wheels. In such cases, removing the chrome from your wheels becomes necessary. This article will guide you through the process of removing chrome from wheels while preserving their original condition.

Before diving into the process, it's crucial to note that removing chrome from wheels requires patience, precision, and proper safety measures. It is best to seek professional assistance if you are unsure about tackling this task on your own.

The three primary methods for removing chrome from wheels are mechanical stripping, chemical stripping, and sandblasting. Each method has its advantages and disadvantages, so let's explore them individually.

1. Mechanical Stripping:
Mechanical stripping involves using abrasive materials such as sandpaper, steel wool, or wire brushes to physically remove the chrome layer from the wheels. This method is time-consuming and labor-intensive, but it offers greater control and avoids potential damage to the underlying metal.

Begin by thoroughly cleaning the wheels to remove any dirt or grime. Then, using medium-grit sandpaper (around 80-120 grit), gently rub the chrome surface in small circular motions. Be sure not to apply excessive pressure, as this could scratch or gouge the wheel's surface. Repeat this process until most of the chrome layer is removed.

To tackle hard-to-reach areas or intricate designs, use steel wool or wire brushes. Remember to carefully remove all remaining traces of chrome before moving on to the next step.

2. Chemical Stripping:
Chemical stripping involves using specialized paint strippers or chrome removers to dissolve the chrome layer chemically. This method is relatively faster than mechanical stripping, but it requires caution due to the harmful nature of the chemicals involved.

Start by wearing protective gloves, goggles, and working in a well-ventilated area. Apply the chosen chrome remover to the wheels using a brush or spray bottle, ensuring complete coverage. Allow the chemical to sit for the recommended time specified on the product label.

After the designated time, you can use a plastic scraper, nylon brush, or steel wool to gently remove the softened chrome layer. Take care not to apply excessive force to avoid damaging the wheel's surface. Repeat this process until all the chrome has been removed.

3. Sandblasting:
Sandblasting is an aggressive method that involves forcefully spraying high-pressure abrasive materials onto the chrome surface to remove it. This technique requires specialized equipment and expertise, making it a viable option for professionals with access to proper facilities.

During sandblasting, aluminum oxide or crushed glass media is propelled by compressed air onto the chrome-plated surface. The abrasives break down the chrome layer, which can then be easily rinsed off. However, sandblasting may cause pitting or roughening of the underlying metal, requiring additional refinishing processes.

Once you have successfully removed the chrome from your wheels, it is essential to restore their appearance and protect them against future damage. You can achieve this through various methods, such as:

1. Polishing and Buffing:
Using polishing compounds, buffing pads, and a power polisher, carefully polish the bare metal surface to eliminate any scratches or imperfections left behind. This will help restore the wheels' original shine while preparing them for further treatment.

2. Powder Coating or Painting:
To give your wheels a fresh look and enhance durability, consider powder coating or painting them. Powder coating offers a more robust finish and provides protection against corrosion and chips. On the other hand, painting allows you to choose from a wide variety of colors and finishes to match your personal style.

Whichever option you decide to pursue, ensure proper preparation, including degreasing and sanding, before applying the powder coat or paint. This will help ensure a long-lasting and aesthetically pleasing finish.

In conclusion, removing chrome from wheels can be a challenging process but is achievable with the right methods and attention to detail. Whether you opt for mechanical stripping, chemical stripping, or sandblasting, always consider your skill level and safety precautions.

Remember, seeking professional assistance is highly recommended if you lack experience or access to proper equipment. With careful execution and diligent post-removal restoration steps, you can transform your wheels while maintaining their original condition. CNC Milling
