How to Wash & Clean Your Electric Vehicle (EV) Safely

Key takeaways

• You can safely wash an electric vehicle (EV) as long as you follow the manufacturer’s washing instructions.

• Disconnect the charger, close the charge-port door properly, switch off automatic features where required, and follow your manufacturer’s washing instructions.

• Rinse off loose grit first, use automotive shampoo and clean microfibre tools, take extra care around the charge port and sensors, then rinse and dry the car thoroughly.

• Hand washing gives you the most control, while pressure washers and automatic car washes can also be suitable if you follow your EV manufacturer’s guidance.

• Wash your EV about every two weeks, or more often if it is parked outdoors or regularly exposed to bird droppings, tree sap, construction dust, or heavy road grime.

The first time you wash an electric car, you may hesitate to clean around the charging port or wonder whether a pressure washer is safe near a high-voltage vehicle. You may also find yourself second-guessing familiar habits that never seemed worth thinking about with a petrol car.

How to wash an electric car safely 

In practice, washing an EV is usually much more straightforward than it sounds. 

Fortunately, most of the usual car-washing steps still apply, with a few extra checks around the charging port, automated features, and any model-specific instructions from the manufacturer.

Step 1: Prepare your car washing materials

Having everything ready before you start makes it easier to keep dirt from being transferred back onto the paintwork.

Prepare:

• 3 pails: One with automotive shampoo and water, one with clean water for rinsing your wash mitt, and one reserved for cleaning the wheels

• 1 clean microfibre wash mitt for the bodywork

• 2-3 clean microfibre towels for drying the car and wiping smaller areas

• 1 separate wheel brush or mitt for the wheels

• 1 can of compressed air for the charging port

• Automotive shampoo, diluted according to the product instructions

• A hose or pressure washer, if you are using one

• An automotive cleaner for stubborn marks such as tar or tree sap, if needed

You should also keep the wheel-cleaning pail and tools separate to prevent brake dust and road grit from being transferred onto the car’s paint.

Step 2: Disconnect the charger & secure the car 

Before you begin rinsing or washing the car:

• Unplug the charging cable

• Close the charging inlet cover and charge-port door fully. Give it a light press to confirm that it is properly latched

• Close the windows, doors, boot, and sunroof

• Switch off automatic windscreen wipers

• Secure or retract automatic door handles if required

• Fold the mirrors if recommended

You should also check whether your EV has a car wash mode. In some EVs, car wash mode locks the charge port and disables the windscreen wipers, among other functions.

Step 3: Rinse off loose dirt & grit first

Use a hose or pressure washer to rinse the car and remove loose dust, grit, and road debris before washing it with a mitt. Pay extra attention to lower doors, bumpers, and wheel arches, where dirt tends to build up.

This reduces the chance of dragging abrasive particles across the paint during the contact wash.

Step 4: Wash with automotive shampoo 

Use automotive shampoo and a clean microfibre wash mitt. Work from cleaner areas, such as the roof and glass, toward dirtier lower panels.

Rinse the mitt regularly, and use separate tools for the wheels so brake dust and road grit do not end up on the paint.

For stubborn marks such as dried bird droppings, place a microfibre cloth soaked in water or diluted car shampoo over the spot for a few minutes before wiping gently. Use a suitable automotive cleaner for substances such as tree sap or tar rather than scraping them off.

Step 5: Take care around the charge port & sensors 

With the charge-port door properly closed, wash the surrounding bodywork normally, but avoid directing concentrated high-pressure water at:

• The charge-port door

• Cameras and sensors

• Rubber seals

• Loose trim

• Damaged areas

If you are using a pressure washer, keep the nozzle moving and follow the distance recommended in your owner’s manual.

Step 6: Rinse & dry thoroughly 

Rinse your car until no shampoo remains. You should also check the areas where residue tends to accumulate, such as mirrors, door handles, panel gaps, and around the charge-port door.

Dry the car with a clean microfibre towel rather than leaving it to air-dry, which can lead to visible water spots.

Step 7: Clean the charging port

So, how do you clean the charging port of an electric car?

Before setting off:

• Make sure cameras and sensors are clean

• Return folded mirrors or retracted handles to their normal position

• Switch automatic wipers back on if needed

• Exit car wash mode where required

Is it safe to wash an electric car?

Yes. 

EVs are built to handle normal exposure to rain and routine washing, as long as the vehicle is in good condition and you follow the manufacturer’s care instructions. In Singapore, EVs must also meet recognised vehicle safety standards, including safeguards against electrical hazards such as those set out in UN Regulation No. 100.

The main thing to check is your model’s specific washing requirements. Features such as flush door handles, automatic wipers, sensors, and car wash mode may require extra preparation. 

Before using a pressure washer or automatic wash, check the owner’s manual, especially if the vehicle has damaged seals, a faulty charge-port door, or exposed components.

What is the best way to wash EV?

No single washing method suits every EV, but hand washing gives you the most control over the paintwork, charge-port area, cameras, sensors, and other exterior components. 

How to prepare your EV for an automatic car wash

If an automatic car wash sounds more appealing, check your owner’s manual, as required settings vary by EV model. Depending on your vehicle and the type of car wash, you may need to:

• Activate car wash mode

• Select Neutral or a free-rolling setting for a conveyor wash

• Switch off automatic wipers

• Fold the mirrors

• Retract or secure automatic door handles

You should also consider whether the wash uses brushes or is touchless. Brushes can trap grit and leave fine scratches on the paint, while touchless systems avoid physical contact but may use stronger cleaning products.

How often should you wash an electric car in Singapore?

We recommend washing your electric car about once every two weeks. However, you can adjust that schedule based on how you use and park your car:

• About once a week: If you park outdoors, regularly park under trees, drive daily, or frequently encounter construction dust and heavy road grime.

• About every two weeks: If you drive several times a week and usually park in a sheltered car park.

• Up to every three to four weeks: If the car is driven infrequently and kept under cover.

Regular washing is just one part of keeping your EV in good condition. You should also check your tyres, brakes, battery condition, charging habits, and other key components as part of routine EV maintenance.

Look after your EV & prepare for the unexpected

A proper washing routine can help keep your EV’s exterior, cameras, sensors, and charge-port area clean. If you are a first-time electric car owner, however, it is also worth understanding what support is available if you run into an emergency on the road.

This is where EV insurance comes in. Like regular car insurance, it can provide financial support after incidents such as accidents or vehicle damage, while some policies also include benefits relevant to electric vehicles, such as battery-related support or roadside charging assistance.

Under Income's eDrivo Car Insurance, for example:

• Get peace of mind with unlimited replacement for your battery1 in the event it is damaged in an accident.

• Cyber hacking coverage2: protect your car against loss or damage due to malicious cyber acts.

• Public EV charging station cover3 – we cover up to $5,000 for the accidental damage to the charger caused by you or your authorised driver during charging

Frequently Asked Questions (FAQs) about washing an electric vehicle

1. What should you do if the charging port gets wet?

Do not plug the charging cable in straight away if water has entered the charging area. Let the area dry, check for debris or visible damage, and follow your owner’s manual before charging again. If the car shows a warning, have it checked.

2. Can you wax or polish an electric car?

Yes. EV paintwork can generally be waxed or polished like that of other cars. Use products suitable for your vehicle’s finish, and avoid applying polish or coating over camera lenses, sensors, or textured exterior trim unless the product instructions say it is suitable.

3. Should you wash an EV immediately after driving?

It is better to let the car cool first, particularly after a long drive. Hot wheels, brakes, and body panels can cause water or cleaning products to dry too quickly, which may leave marks or make cleaning less effective.
