Chalkboard Cleaning – The O.G Method

Who doesn’t remember as a kid wiping the chalkboard down at the end of the day and someone going outside to bang two erasers together trying to rid them of chalk dust? Every couple of weeks, the blackboard might even get a wash with a sponge and water. But your chalkboard would still be left with some traces of dust or even a faint grey wash leftover. Time to learn how to clean a chalkboard like a pro! We will even explain how to get crayon off a chalkboard for those stubborn chalkboard stains.

Set Up A Good Routine

Try and clean your chalkboard after every use with an eraser. This quick and simple action will remove most of the dust and prevent significant build-up. Reducing build-up will make it easier to maintain and extend the lifetime of your board. Start in the top left-hand corner and work your way down to the boards bottom right to ensure you cover the whole area and use long, consistent strokes to ensure you remove as much dust as possible. 

While water can be an effective way to help clean your chalkboard it can also leave residual stains. Using as little water as possible, try using a squeegee after cleaning to remove excess water from the board and avoid any potential stains. Just like with your eraser, ensure you are using long consistent strokes to avoid any unwanted streaks.

Don’t forget: Although your board may look nice and clean and you are eager to use it again, make sure it has dried out before starting. Using chalk on a wet board will significantly increase build-up, which means more cleaning!

Want to know how to clean a chalkboard using natural products? It’s certainly possible! There are many natural products around the house which you can use to revive your dusty old chalkboard.

Once you’ve done that, prepare a warm bucket of water with half a cup of vinegar. Use as much of this mixture with a cloth as needed to get those extra stubborn marks. White vinegar is best as it is free from colouring compared to other vinegar such as balsamic.

Using Cola

Although not a natural product, many of us have a bottle or two of cola around the house – at the least it is an expensive product that can be picked up from your local shops. Now I know what you’re thinking – isn’t it going to be messy, sticky and ruin my chalkboard? In actual fact, using cola is a fairly easy and effective way to clean a chalkboard.

Dishwashing liquid

Dishwashing liquid is another great product to help you clean your chalkboard. Prepare a warm bucket of water with a few drops of dishwashing liquid in it and apply using a clean, soft cloth to your blackboard.


Windex is perfect for removing liquid chalk. All you need to do is spray some Windex onto your board and let it sit for a period of time before wiping it off with a soft cloth. If you can still see writing after the first run, repeat the process and it should be off in no time.
