How to Clean a Whiteboard: 5 Step Method

If your board looks dingy or you accidentally used a permanent marker, don’t panic. We have the best methods to restore your whiteboard to its original shine using simple household items.

Types of Whiteboards

Not all whiteboards are created equal. Knowing which type of material you own will help you choose the right cleaning method and avoid damaging the surface.

Melamine

Melamine boards consist of a plastic resin backed by pressboard. These are the most common and affordable options, but they are also the most porous.

Because the surface absorbs ink easily, melamine is prone to ghosting (faint remnants of old writing). You need to clean these immediately after use to prevent permanent staining.

Porcelain

Porcelain (or ceramic) whiteboards feature a hard enamel surface backed by steel. They are highly durable, magnetic, and much more resistant to staining than melamine.

Since the ceramic surface is non-porous, ink sits on top rather than soaking in. You can use standard markers and cleaners without worrying too much about heavy scrubbing.

Tempered Glass

Glass whiteboards are the gold standard for durability and aesthetics. Made from toughened glass, they are completely non-porous.

You rarely see ghosting on glass boards because the ink cannot penetrate the surface. While they are expensive, they are incredibly low-maintenance and can withstand harsh cleaners if necessary.

How to Clean a Whiteboard That Won’t Erase

If you have old ink that refuses to budge, or if someone accidentally used a Sharpie, this method works like magic. It rehydrates the dried ink so you can wipe it away.

• Time: 10 minutes
• Difficulty: Easy

What You’ll Need

• Fresh dry-erase marker (dark colors work best)
• Whiteboard eraser
• Whiteboard cleaner (like Expo)
• Microfiber cloth
• Water

1. Scribble Over the Stain

Take your fresh dry-erase marker and color completely over the dried stain or permanent marker ink. The solvent in the fresh ink will dissolve the hardened bond of the old ink.

2. Wait and Erase

Let the fresh ink sit for about 30 seconds to one minute. Use your standard whiteboard eraser to wipe away the markings. The old stain should peel away with the new ink. Repeat this step if stubborn spots remain.

3. Spray and Wipe

Once the bulk of the ink is gone, spray the area with a commercial whiteboard cleaner or rubbing alcohol. Wipe it down with a cloth to remove any oily residue.

4. Rinse With Water

Chemical residues can build up over time. Dampen a clean cloth with plain water and wipe the board one last time, then dry it immediately.

How to Clean a Whiteboard After Each Use

Routine maintenance is the secret to longevity. If you use your board daily, follow these simple steps to keep it looking brand new.

• Time: 5 minutes
• Difficulty: Easy

What You’ll Need

• Whiteboard cleaner OR DIY solution (50/50 water and rubbing alcohol)
• Whiteboard eraser
• Microfiber cloths

1. Dry Erase First

Always start by removing loose dust and ink with a felt eraser. This prevents you from smearing ink sludge across the board once you add liquid.

2. Apply Cleaner

Spray your commercial cleaner or DIY alcohol mixture onto the board. A light mist is all you need; do not soak the frame or tray.

3. Wipe Clean

Use a clean microfiber cloth to wipe the board in a circular motion. This lifts the dissolved ink and dust.

4. Dry the Surface

Follow up with a dry section of the cloth. Leaving a whiteboard wet can cause future ink to bubble or smear.

Whiteboard Cleaning Hacks

If you don’t have Expo spray on hand, check your pantry or bathroom cabinet. These household items are surprisingly effective at cutting through ink and grime.

Rubbing Alcohol (Isopropyl)

This is the main ingredient in most commercial cleaners. Mix 90% or 99% isopropyl alcohol with water in a 1:1 ratio. It cuts through ink oil instantly and dries fast.

White Vinegar

The acidity in distilled white vinegar breaks down buildup. Mix a teaspoon of vinegar into a cup of water. It smells strong, but it is effective for removing water spots and light grime.

WD-40

The oil in WD-40 lubricates the surface and lifts old stubborn ink. Spray a small amount onto a cloth (never directly on the board) and wipe the stain. You must clean the board with soapy water afterward to remove the oily slickness, or new markers won’t write properly.

Glass Cleaner (Windex)

For tempered glass boards, Windex is perfect. For melamine or porcelain, use it sparingly. It removes stains well but can strip the board’s conditioning if used too often.

Dish Soap

A drop of mild dish detergent like Dawn mixed with water cuts through grease and finger oils. This is great for a weekly deep clean.

Magic Eraser (Use with Caution)

Melamine sponges (Magic Erasers) are essentially micro-sandpaper. They will remove stains, but they also strip the smooth finish off the whiteboard. Only use this on old boards that are already on their last legs.

Nail Polish Remover (Acetone)

Acetone is a powerful solvent. Apply a small amount to a cotton ball or cloth to rub out permanent marker stains. Like the Magic Eraser, this is harsh on the surface coating, so use it as a spot treatment only.

Toothpaste

Non-gel toothpaste acts as a mild abrasive. Apply a dab to the stain and rub gently with a wet cloth. Wipe clean thoroughly to remove the sticky residue.

Hairspray

Most hairsprays contain alcohol. Spray it on the ink, let it sit for a minute, and wipe it away with soapy water. The soap is necessary to remove the sticky hairspray hold.

What Not to Use on a Whiteboard

To prevent ruining the surface of your board, steer clear of these damaging products:

• Abrasive scrubbers: Steel wool, the rough side of a kitchen sponge, and baking soda will scratch the finish, creating traps for ink to settle permanently.
• Wax-based polish: Furniture polishes leave a film that makes markers streak and smear.
• Bleach: This is too harsh for most synthetic whiteboard surfaces and can cause discoloration.
• Oily skin: Avoid wiping the board with your bare hands. Natural skin oils mix with ink dust to create smears that are hard to erase.
• Paper towels: While common, paper towels are abrasive over time. They also leave behind lint. Stick to soft microfiber cloths.

How to Recondition a Whiteboard

If your board is old and porous, ink will stick no matter how much you clean it. You can try reconditioning the surface with automotive wax to fill in the microscopic scratches.

• Time: 1 hour
• Difficulty: Intermediate

What You’ll Need

• Deep cleaning solution (Isopropryl alcohol)
• Carnauba-based car wax (like Chemical Guys Banana Spray)
• Clean microfiber towels
• Buffing cloth

1. Deep Clean

Clean the board thoroughly using the alcohol or “fresh marker” method. The surface must be completely free of dust and ink before you seal it.

2. Apply Wax

Squeeze a small amount of liquid carnauba wax onto a soft cloth. Apply it to the whiteboard in circular motions, covering the entire surface evenly.

3. Let It Haze

Allow the wax to dry until it turns into a cloudy haze. This usually takes 10 to 20 minutes depending on the product instructions.

4. Buff It Out

Take a clean, dry terry cloth or microfiber towel and buff the wax off. Keep rubbing until the surface feels slick and looks glossy. This fills the pores and allows markers to erase smoothly again.

How to Clean a Whiteboard Eraser

A dirty eraser just spreads ink back onto the board. You should clean your eraser whenever the felt looks matted or saturated with dust.

1. Remove dust: Take the eraser outside and clap it against a wall or use a vacuum hose to suck out loose dust.
2. Soak: Mix a bowl of warm water and a teaspoon of dish soap. Submerge the felt side of the eraser for 15 minutes.
3. Scrub: Use an old toothbrush to gently scrub the felt and release the ink particles.
4. Rinse and dry: Rinse under cold water until the water runs clear. Press it onto a towel to remove excess moisture and let it air dry completely in the sun.

FAQs

Why Do Whiteboards Stop Erasing?

Whiteboards stop erasing well when the protective surface coating wears down. Over time, frequent use and harsh cleaners strip the slick finish, exposing the porous material underneath. This allows ink to seep into the board’s pores, causing “ghosting” and stains that are difficult to wipe away.

Can You Use Baby Wipes on a Whiteboard?

Yes, baby wipes are great for quick cleaning. Most contain small amounts of alcohol and mild detergents that lift fresh ink effectively. However, some brands contain lotions or oils that may leave a streaky residue, so it is best to follow up with a dry cloth wipe.

Can You Use Hand Sanitizer to Clean a Whiteboard?

Yes, hand sanitizer works in a pinch because of its high alcohol content. Apply a dime-sized amount to a paper towel or cloth and rub the stain. Be sure to wipe the board with a damp cloth afterward, as the glycerin in sanitizer can leave a sticky film.

What Are the Best Markers to Use on a Whiteboard?

Stick to high-quality dry-erase markers specifically designed for whiteboards. Avoid low-odor markers if you have a glass board, as they sometimes lack the bold pigment needed. Popular trusted brands include:

• Arteza Dry Erase Markers (Great for glass)
• U Brands Liquid Glass Markers
• Expo Low Odor Markers (The industry standard)

How Do You Remove Permanent Marker From a Whiteboard?

The easiest way to remove permanent marker is to trace over it with a fresh dry-erase marker. The solvents in the wet dry-erase ink dissolve the permanent ink. Let it sit for a few seconds, then wipe it all away with a standard eraser or cloth.

Whiteboard Wrap Up

Keeping your whiteboard clean doesn’t require expensive supplies. Regular maintenance is the key. Erase your board at the end of every day, and give it a wet wipe-down with alcohol or whiteboard cleaner once a week.

If you encounter stubborn stains, remember the “fresh marker” trick before reaching for abrasive scrubbers. With these simple habits, your whiteboard will stay bright, white, and ready for your next big idea.
