How To Remove Chrome Off Rims

Chrome wheels can add a fantastic touch to your vehicle, but sometimes they get damaged, pitted, or you simply want a different look. Stripping the chrome off your rims can seem like a daunting task, but with the right tools, patience, and method, it's definitely achievable. This guide will walk you through several methods, from DIY approaches to professional services, and help you decide which is the best option for your situation.

Understanding Your Options

Before we dive into the how-to, it's important to understand the different approaches to removing chrome and the pros and cons of each. The most common methods are:

• Chemical Stripping: Using strong chemicals to dissolve the chrome plating.
• Mechanical Stripping (Grinding/Sanding): Physically removing the chrome layer using abrasive tools.
• Electrolytic Stripping (Reverse Plating): Reversing the plating process to detach the chrome.
• Professional Media Blasting: Having a professional use specialized equipment to blast the chrome off.

Each method has its own level of difficulty, cost, and potential risk to the underlying wheel. Let's explore them in more detail.

Method 1: Chemical Stripping

Chemical stripping is often considered the easiest DIY method. It involves submerging the rims in a chemical solution that dissolves the chrome. While relatively straightforward, it's crucial to handle these chemicals with extreme caution.

Tools and Materials Needed:

• Appropriate Chemical Stripper: Look for specifically formulated chrome strippers. Muriatic acid (hydrochloric acid) is sometimes used, but it's highly corrosive and dangerous – exercise extreme caution if considering this option. Always research compatibility with the wheel material (aluminum, steel, etc.).
• Large Plastic Container: Big enough to fully submerge the rims. Plastic is crucial as the chemicals will react with metal containers.
• Safety Gear: Essential! Includes chemical-resistant gloves, eye protection (goggles or a face shield), and a respirator (especially if using strong acids).
• Wire Brush: For scrubbing away loosened chrome.
• Neutralizing Solution: Baking soda and water to neutralize any acid residue.
• Water: For rinsing.

Steps:

1. Prepare the Area: Work in a well-ventilated area, preferably outdoors. Protect the surrounding area with plastic sheeting.
2. Clean the Rims: Thoroughly clean the rims with soap and water to remove any dirt, grease, or debris.
3. Apply the Chemical Stripper: Carefully pour the chemical stripper into the plastic container. Follow the manufacturer's instructions for dilution (if required) and safety precautions.
4. Submerge the Rims: Slowly and carefully submerge the rims in the chemical solution. Ensure they are fully covered.
5. Wait: Allow the rims to soak for the recommended time (usually several hours or overnight). Check the progress periodically. The chrome should start to bubble and peel.
6. Scrub: Once the chrome has loosened, use a wire brush to scrub away the remaining chrome.
7. Rinse: Thoroughly rinse the rims with water.
8. Neutralize: If you used an acid-based stripper, neutralize the rims with a baking soda solution (mix baking soda with water to form a paste).
9. Final Rinse: Rinse the rims again with water.
10. Inspect: Inspect the rims for any remaining chrome. Repeat the process if necessary.

Pros:

• Relatively inexpensive.
• Can be done at home.

Cons:

• Dangerous chemicals require extreme caution.
• Can be time-consuming.
• May not be effective on heavily pitted or damaged chrome.
• Risk of damaging the underlying wheel material if the chemical is too strong or the soaking time is too long.

Approximate Cost:

The cost of chemicals can range from $50 to $150, depending on the type and quantity needed. Safety gear will add another $30-$50.

Method 2: Mechanical Stripping (Grinding/Sanding)

Mechanical stripping involves using abrasive tools to physically remove the chrome layer. This method requires more effort and skill, but it can be effective on stubborn chrome.

Tools and Materials Needed:

• Angle Grinder: With various grinding and sanding discs. Start with a coarse grit (e.g., 40-grit) and gradually move to finer grits (e.g., 120-grit, 220-grit).
• Sanding Block: For hand-sanding hard-to-reach areas.
• Safety Gear: Essential! Includes safety glasses, a dust mask or respirator, and gloves.
• Ear Protection: Grinding can be noisy.
• Paint Stripper (Optional): Can help soften the chrome before grinding.

Steps:

1. Prepare the Area: Work in a well-ventilated area. Protect the surrounding area with plastic sheeting.
2. Clean the Rims: Thoroughly clean the rims with soap and water.
3. (Optional) Apply Paint Stripper: Apply paint stripper to the chrome and let it sit for the recommended time. This can help soften the chrome and make it easier to grind.
4. Grind: Using the angle grinder with a coarse grinding disc, carefully grind away the chrome. Keep the grinder moving to avoid overheating and damaging the underlying metal.
5. Sand: Switch to a sanding disc and gradually move to finer grits. This will help smooth out the surface and remove any remaining chrome.
6. Hand-Sand: Use a sanding block to hand-sand hard-to-reach areas.
7. Inspect: Inspect the rims for any remaining chrome or imperfections. Repeat the process if necessary.
8. Clean: Thoroughly clean the rims with a degreaser to remove any sanding dust and residue.

Pros:

• Can be effective on stubborn chrome.
• Relatively inexpensive (if you already own the tools).

Cons:

• Requires more skill and effort.
• Can be time-consuming.
• Risk of damaging the underlying wheel material if you're not careful.
• Creates a lot of dust.

Approximate Cost:

If you need to purchase an angle grinder, expect to spend $50-$150. Sanding discs and safety gear will add another $20-$40.

Method 3: Electrolytic Stripping (Reverse Plating)

Electrolytic stripping, also known as reverse plating, is a more advanced method that uses electricity and a chemical solution to reverse the chrome plating process. This method is generally more effective and less damaging than chemical stripping or mechanical stripping, but it requires specialized equipment and knowledge.

This method is not recommended for beginners due to the complexity and potential hazards.

Tools and Materials Needed:

• Electrolyte Solution: Specifically designed for chrome stripping (typically contains sodium hydroxide).
• Rectifier: A DC power supply with adjustable voltage and amperage.
• Anode: A piece of metal (usually steel or stainless steel) that acts as the positive electrode.
• Cathode: The wheel itself, which acts as the negative electrode.
• Tank: A non-conductive tank to hold the electrolyte solution.
• Safety Gear: Essential! Includes chemical-resistant gloves, eye protection, and a respirator.

Steps (Simplified Overview):

1. Prepare the Solution: Mix the electrolyte solution according to the manufacturer's instructions.
2. Connect the Electrodes: Connect the anode to the positive terminal of the rectifier and the wheel (cathode) to the negative terminal.
3. Submerge the Wheel: Submerge the wheel in the electrolyte solution, ensuring that it is not touching the anode.
4. Apply Current: Turn on the rectifier and adjust the voltage and amperage according to the manufacturer's instructions.
