Why Do MacBook Chargers Turn Yellow?

Have you ever wondered why MacBook chargers eventually become yellow? It can be confusing to see this, and you might wonder if it is normal. 

In this article, we’ll examine the causes of this coloring issue and provide helpful prevention advice. Watch as we continue to solve the problem and make sure your MacBook charger is always in excellent condition.

What Causes MacBook Chargers to Turn Yellow?

Users can take steps to keep their chargers in good condition for longer by being aware of the reasons why MacBook chargers turn yellow.

1. Overheating

Overheating is one of the main reasons why MacBook chargers start to turn yellow. The continual use of the charger produces heat, which might cause a gradual color change in the plastic casing.

During charging sessions, exposure to high temperatures on a constant basis contributes to the discoloration process.

2. Environmental Factors

The environment has a big impact on how quickly MacBook chargers turn yellow. Over time, discoloration can occur because of exposure to sunshine, dust, and other pollutants. Sunlight’s UV rays can break down the plastic’s molecular structure, changing its appearance.

3. Chemical Reactions

Some chemical elements in the charger’s plastic case may react with heat or the environment to produce a yellowish color. The charger loses its original color due to the plastic oxidation brought on by these events.

4. Material Quality

The level of plastic used to manufacture MacBook chargers might affect how easily they turn yellow. Higher-grade plastics may be less vulnerable to discoloration than inferior materials.

5. Usage and Handling

The yellowing process might be accelerated by overuse and poor handling. Particularly in areas with high humidity, the accumulation of oils, dirt, and sweat from hands might eventually affect the charger’s look.

6. Age and Wear

Just as with any electrical item, MacBook chargers can suffer from the effects of aging and use. The plastic case naturally experiences wear and tear over time and with repeated use, which causes a progressive color change.

Impact on Charger Performance and Safety

The performance of MacBook chargers may not be significantly impacted by their color fading if the internal parts are functional and in good condition.

However, using a colored charger raises certain potential safety issues:

1. Heat Dissipation

The yellowing plastic could affect the charger’s capacity to dissipate heat effectively over time.

Inefficient heat dissipation during charging can result in overheating problems, which might affect the charger’s functionality and even harm the Macbook being charged.

2. Electrical Insulation

Discoloration may indicate changes in the plastic’s characteristics, which might compromise the material’s ability to provide electrical insulation.

Insulation damage can result in electrical leaks, short circuits, or other electrical dangers, putting the charger and the connected device in danger.

3. Structural Integrity

Plastic that is discolored may have experienced physical changes because of exposure to numerous conditions. The charger can be more susceptible to accidental drops or impacts if its structural integrity is damaged.

4. Potential for Counterfeit Products

In certain cases, the yellowing of a MacBook charger may be a sign that poor-quality or fake parts were used.

These poor chargers could violate safety regulations and present serious dangers, such as electric shocks, fires, or damage to the MacBook.

How Can You Get the Yellow Color Off Your MacBook Charger?

To prevent any electrical dangers, make sure the charger is unplugged from the power source and your MacBook before beginning any cleaning.

1. Clean with Mild Detergent

Use a soft cloth or sponge soaked with water and a small amount of mild detergent to clean. Wipe the charger’s surface gently, paying particular attention to the discolored spots. Keep water out of the charging ports.

2. Rubbing Alcohol or Isopropyl Solution

If the mild detergent doesn’t work, try rubbing alcohol or isopropyl solution. Use the alcohol to wet a clean cloth and gently rub the areas that have become yellow.

3. Baking Soda Paste

Making a paste out of baking soda and water, you can apply it to the parts that have turned yellow. After letting it sit for a while, use a soft towel to scrub it gently. 

4. Hydrogen Peroxide

You can also use a towel to apply diluted hydrogen peroxide (3% solution) to the regions that have become yellow. Before using, test it on a tiny area and then thoroughly rinse.

If everything fails, consider restoring the charger’s appearance with plastic-safe paint or coating. Make sure it is secure to use and compatible with devices.

Preventive Measures and Maintenance Tips

Consider using the following precautions and maintenance advice to keep your MacBook charger in excellent condition and increase its lifespan:

Keep it Clean: Regularly clean the charger with a soft, lint-free cloth to get rid of dust, oils, and dirt. By doing this, accumulation and the possibility of discoloration are reduced.

Avoid Extreme Temperatures: Keep the charger dry and cool, away from harsh sunlight and heat sources. Temperatures that are too high or too low can hasten the fading process.

Proper Handling: The charger should be handled carefully to prevent unnecessary wire bending or twisting. This maintains the charger’s structural integrity.

Use a Cable Organizer: By purchasing a cable organizer, you can assist in reducing needless strain on the charger’s cord, hence minimizing wear and tear.

Original Apple Charger: Use only original Apple chargers or approved third-party chargers made expressly for your model of MacBook. Avoid purchasing cheap imitations that could reduce performance and safety.

Storage During Travel: To prevent the charger from any harm, keep it in a separate compartment or protective case while traveling.

Is It Dangerous when MacBook Charger Turns Yellow?

If the charger is working properly, your safety might not necessarily be at immediate risk if your MacBook charger turns yellow. However, the yellowing process may provide some security problems.

To reduce possible risks and guarantee optimum performance, consider replacing the charger with a genuine and compatible Apple charger if you observe significant yellowing, damage, or overheating.


While the MacBook charger becoming yellow may not immediately present a threat, caution must be taken. A yellowing of the material could be a sign of overheating or environmental exposure, which might harm structural integrity. 

Safety depends on regular inspections, appropriate handling, and the use of legitimate charges. If substantial yellowing or problems continue, consider replacing the charger with an authentic Apple product to guarantee safety and the best performance.
