Removing chrome plating from plastic parts can be a tricky process. While some suggest using diluted bleach, others recommend trying floor cleaner, oven cleaner, or brake fluid. It's important to note that the process may vary depending on the type of plastic and the thickness of the chrome plating. In some cases, it may be necessary to use a combination of methods or to repeat the process multiple times to completely remove the chrome. Additionally, it's always a good idea to take the necessary safety precautions, such as wearing gloves and safety goggles, when working with chemicals.

What You'll Learn
Soak in brake fluid
Soaking plastic in brake fluid is a common method for stripping chrome. It is often used in scale modelling to remove paint and chrome from parts.
To do this, brush on a light coating of brake fluid and let it sit for at least 15 minutes. Then, use steel wool to rub the parts until the chrome has been removed. You may need to reapply the brake fluid a few times for stubborn spots. This method will leave you with clean plastic.
It is important to note that brake fluid can make ABS plastic brittle and weaken its structure. This may not be an issue for some plastic parts, but it is something to be aware of before starting the process.
There are alternative methods to stripping chrome from plastic, such as using oven cleaner or bleach. However, these methods may not be as effective as using brake fluid. For example, one person reported that oven cleaner did not remove the chrome from their plastic grill, and they had to trash the part.

Use a strong detergent
If you want to strip chrome from plastic, one option is to use a strong detergent. This method is effective and will not harm the plastic. Mr Muscle Professional Floor Cleaner is a good option and will quickly remove the chrome. Simply soak the chrome-plated plastic in the detergent, and the chrome will come off in a short time. If you don't have access to this specific detergent, ordinary washing-up liquid will also work, although it will take longer as it is a milder detergent.
Another option for a strong detergent is to use an oven cleaner. This can be sprayed on and left overnight in an airtight container. By morning, the chrome plating should be gone. One user recommends Easy Off oven cleaner, which can strip chrome in about 10 minutes.
If you are looking for a more natural option, household ammonia is a good choice. Pour a small amount into a plastic container, and the chrome plating should come off overnight. However, this method may not work if the plastic has been clear-coated.
It is important to note that when using any of these methods, you should always wear gloves and safety goggles to protect yourself from any potential harm. Additionally, some of these chemicals may have strong fumes, so ensure you are in a well-ventilated area.
Overall, using a strong detergent is an effective and safe way to strip chrome from plastic without causing any damage to the underlying material.

Try diluted bleach with a 12V battery
Stripping chrome from plastic can be a challenging task, and it may require some experimentation to find the most effective method for your specific situation. One approach that has proven successful for some is the use of diluted bleach in combination with a 12V battery. Here's a step-by-step guide on how to try this method:
Prepare the Materials
Firstly, gather your supplies. You will need diluted bleach, a 12V battery, a plastic container, a piece of scrap metal, and some safety gear, including gloves and eye protection. It is also recommended to work in a well-ventilated area or outdoors to avoid inhaling any fumes.
Set Up the Battery
Connect the positive terminal of the 12V battery to the metal object from which you want to strip the chrome. Ensure that the connection is secure and that the metal surface is fully in contact with the battery terminal. Then, connect the negative terminal of the battery to the piece of scrap metal. This setup will create an electrical current that will assist in the stripping process.
Soak the Object in Diluted Bleach
Fill the plastic container with enough diluted bleach to completely submerge the object you are treating. Refer to the dilution instructions on the bleach container and prepare a solution suitable for your specific task. Place the object into the bleach solution, ensuring that it is fully immersed. The bleach will react with the chrome, causing it to dissolve over time.
Monitor the Process
Keep an eye on the object as it soaks in the bleach solution. Depending on the thickness of the chrome plating and the concentration of the bleach, it may take several hours or even longer for the chrome to strip completely. You may need to agitate the object or brush it gently with a soft-bristled brush to speed up the process and ensure that the bleach reaches all areas.
Rinse and Inspect the Object
Once you are satisfied that the chrome has been sufficiently stripped, remove the object from the bleach solution and rinse it thoroughly with clean water. Examine the object to ensure that all traces of chrome have been removed. If there are any remaining chrome deposits, you may need to repeat the process or try a different method.
Safety Precautions
It is important to exercise caution when working with chemicals like bleach. Always wear protective gear, including gloves and eye protection, to safeguard your skin and eyes from irritation or injury. Ensure that the work area is well-ventilated, and avoid inhaling any fumes. Keep children and pets away from the work area, and properly dispose of any leftover bleach solution according to local regulations.

Soak in household ammonia
Soaking in household ammonia is an effective method to strip chrome from plastic. This method is recommended by several people and can be done using an ultrasonic cleaner or a simple plastic container. The process involves pouring a small amount of household ammonia into the container and letting the chrome-plated plastic part soak in it. The duration of the soak can vary, but it typically takes a few hours or overnight for the chrome plating to come off.
It is important to note that household ammonia should be handled with caution as it is a strong chemical that can cause watering eyes. When working with ammonia, it is recommended to wear protective gear, such as gloves and eye protection. Proper ventilation or working outdoors is also advised to avoid inhaling the fumes.
The effectiveness of this method may depend on the type of plastic and the thickness of the chrome plating. While household ammonia can successfully remove chrome plating, it may not always remove the clear coat or primer that is sometimes present on plastic parts. These additional coatings may require a different approach or a longer soaking time.
Before soaking the chrome-plated plastic in ammonia, it is advisable to do a small test on a similar piece of plastic to ensure that the process does not damage the underlying material. Additionally, if the chrome-plated plastic has intricate details or tight corners, additional steps may be necessary to ensure complete removal of the chrome. This could include scrubbing with a toothbrush and warm soapy water after the soaking process.
Overall, using household ammonia is a straightforward and relatively safe method to strip chrome from plastic. With the proper precautions and techniques, this method can effectively remove chrome plating without damaging the plastic underneath. However, it is always important to exercise caution when working with chemicals and to follow the necessary safety procedures.

Use an oven cleaner
Oven cleaner is an effective method for removing chrome plating from plastic parts. It is important to use a commercial-grade oven cleaner, which usually comes in an aerosol can as a foam or liquid spray.
To start, ensure the chrome part is protected from any potential damage by the oven cleaner. If there are any other metal parts cast into the housing, coat them with a waterproof layer. This is because the oven cleaner may eat into the metal, and slightly etch the plastic, if left for too long.
Once you have prepared the chrome part, apply a generous coating of the oven cleaner. Allow the cleaner to sit and soak for around 10 minutes. Then, simply wipe away the chrome and the cleaner. You may need to repeat this process a few times to ensure all the chrome is removed, especially in tight corners.
One user suggests placing the chrome part in an airtight container overnight after spraying with the oven cleaner. This method ensures the plating is removed without the need for scrubbing.
