How to Clean the EV Charger: A Step-by-step Guide


In recent years, electric vehicles (EVs) have become increasingly popular as a more environmentally friendly transportation option. Along with the rise of EVs, the need for electric vehicle chargers has also grown. These chargers, usually installed in homes, public parking lots, and other public spaces, require regular cleaning to maintain functionality and extend their lifespan. In this blog post, we will discuss how to clean an EV charger and the steps to keep it in good condition.

What is EV Charger?

An EV charger is an electronic device that transfers electricity to an electric vehicle’s battery to charge it. It can be either a portable charger connected to an outlet or a more permanent device installed at a specific location. EV chargers come in different shapes and sizes and can be categorized into three types: Level 1, Level 2, and DC fast chargers. Level 1 chargers use a standard 120V outlet and can take up to 24 hours to fully charge an EV, while Level 2 chargers use a 240V outlet and can charge an EV in a few hours. On the other hand, DC fast chargers can charge an electric car in as little as 30 minutes.

Importance of cleaning an EV charger

Keeping a charger clean is crucial to maintaining its functionality and preventing potential hazards. Over time, dirt, dust, and debris can accumulate on the device, affecting its performance and leading to corrosion or electrical problems. Regular cleaning can prevent these issues and prolong the lifespan of the charger. Moreover, maintaining a clean charging station can also ensure that it charges the vehicle’s battery efficiently and safely.

Possible Risks and Dangers of not Cleaning Your EV Charger

If you neglect to clean your charger regularly, you may be exposing your electric car and yourself to some risks and dangers, including:

Electric Shock: Water and electricity don’t mix, and a dirty charging station can trap moisture or debris inside it, leading to electric shock or short circuits.

Fire Hazards: A dirty charger can also pose a fire hazard. Dust, dirt, and debris can accumulate inside the device and create a spark or arc that could ignite a fire.

Reduced Charging Performance: A dirty charging station can impede the efficient flow of electricity, leading to slower charging times or even a malfunction of the charging station.

Supplies Needed for Cleaning the EV Charger

When cleaning a charger, you don’t need any fancy equipment or tools. All you need are simple supplies you probably already have at home. Here are the supplies you will need:

Cleaning Solution

A cleaning solution is one of the most important supplies you’ll need to clean your EV charging station. It’s essential to use a cleaning solution that your EV charging station manufacturer explicitly recommends. Using the wrong type of cleaning solution can damage the charging station and void your warranty. You can find cleaning solutions for EV chargers at most hardware stores or order them online.

Microfiber Cloth

Another important supply you’ll need to clean your EV charging station is a microfiber cloth. Microfiber cloths are great for cleaning because they are soft, absorbent, and won’t scratch the surface of your charging station. When choosing a microfiber cloth, choose one that is clean and free of debris or dirt.


In addition to a cleaning solution and microfiber cloth, you’ll also need some water to rinse your charger after cleaning it. It’s important to use clean, cold water for rinsing. Avoid using hot water, as it can damage the charger.

Optional: Soft-Bristled Brush

If your EV charging station is particularly dirty or has hard-to-reach areas, you may also want to use a soft-bristled brush. A soft-bristled brush can help you clean any dirt or debris stuck in the crevices of your charging station. When using a soft-bristled brush, make sure to use gentle, circular motions to avoid scratching the surface of your charger.

Cleaning your charging station is a simple maintenance task that requires just a few basic supplies. By using the right cleaning solution, microfiber cloth, and water, you can keep your charger clean and functioning properly for years to come.

Steps To Clean An EV Charger

Here are the steps to follow in cleaning an EV charger:

  1. Turn off the charger: Before you start to clean, make sure you have turned off the charger to avoid any electrical hazards.
  2. Unplug the charger: Unplug the charger from the power source to ensure no power flows through it while you want to clean it.
  3. Remove debris and dust: Use a soft-bristled brush or a dry microfiber cloth to remove debris or dust from the charger. Be gentle and avoid scratching the surface.
  4. Apply the cleaning solution: Apply the cleaning solution recommended by the manufacturer to a microfiber cloth. Do not spray the cleaning solution directly on the charger, as it can damage the electronics.
  5. Clean the charger with a microfiber cloth:Using the microfiber cloth, gently wipe down the charger’s surface, paying attention to any areas with visible dirt or grime. Be sure to wipe down the cords and connectors as well.
  6. Rinse the charger with water: Once you’ve finished wiping down the charger with the cleaning solution, rinse it off with water using a separate clean microfiber cloth. Do not use a hose or pressure washer to rinse off the charger, as this can damage the electronics.
  7. Dry the charger: After rinsing off the charger, dry it with a clean but dry towel or microfiber cloth. Make sure it is completely dry before plugging it back in.

Tips For Cleaning An EV Charger

Properly cleaning a charging station is vital for ensuring it functions efficiently and safely. Here are some tips to keep in mind:

Avoid using abrasive materials or harsh chemicals

Avoid using abrasive materials or harsh chemicals to clean the charger. This includes anything that can scratch or damage the surface of the charging station. Abrasive materials such as steel wool, scrubbing pads, or harsh chemicals can cause the surface of the charging station to become scratched or discolored. It’s best to use a soft microfiber cloth to clean the charger.

Do not use a pressure washer or hose to clean the charger

As briefly mentioned before, using a pressure washer or hose to clean the charger is not recommended. The high pressure of the water can cause damage to the charger, especially if it enters any of the electrical components. This can cause electrical faults, corrosion, or even a short circuit. It’s best to use a damp cloth and avoid getting any water into the electrical components of the charger.

Clean the charger regularly

Regular charger cleaning is essential to maintain its efficiency and prolong its lifespan. Ideally, you should clean your EV charging station every three to six months. If it is in a dusty or dirty environment, you may need to clean it more often. Make sure to clean the charger thoroughly, including the cable and plug.


Regularly cleaning your electric vehicle charger is essential to ensure its proper functioning and longevity. Not only dust, dirt, and debris can potentially cause damage to the electrical components. Environmental factors such as rain, snow, and extreme temperatures can also affect the charger’s performance. Therefore, it is crucial to maintain a clean EV charger to keep it functioning correctly. Cleaning a charging station is a simple and straightforward process that people can finish using household cleaning supplies. By following the steps outlined in this guide, you can ensure that your charging station is always in top condition, providing a reliable and fast charging experience for your electric vehicle.

Moreover, keeping your EV charging station clean and well-maintained also helps preserve the environment. Electric cars are becoming more popular due to their low carbon emissions, and by maintaining your charging station correctly, you are playing your part in reducing your carbon footprint.
