Sanding can create a huge junk of dust within a short time, whether you are using hand-held sandpaper or a power sander. That’s why the easiest method to remove dust is to brush it away with a dusting brush.

You can also improvise and use a clean and dry paintbrush to tackle the same dust problem. This method is best suited for wood furniture and hard-to-reach areas of the wood.

The steps

 Step 1: Use a soft-bristled brush to brush the sand dust away from the surface.

Aim to remove as much as possible. Remember to use gentle brushing strokes not to lift the dust and cause them to fly and scatter further.

Step 2: Collect the accumulated dust in a dustpan and dispose of it.

Step 3: Wipe the surface clean using a cloth dampened in water.

Using a Vacuum

A vacuum cleaner is an essential item in most households. Other than using it to keep the home clean, you can bring it to your workshop, and it will help you keep your space cleaner. Most electric sanders have a vacuum installed in them.

This method would be for you if you sanded your wood surfaces using a palm-sandpaper or a sander without the vacuum.

The Steps

Step 1: Switch on your shop vacuum (preferably a soft vacuum hose nozzle) and hover it on areas covered with loose dust.

Step 2: Ensure the vacuum has sucked up all the dust on and around the wood surfaces.

Step 3: Wipe the remaining dust from the wood using a cloth soaked in mineral spirits or water or denatured alcohol.

Using Air Compressor

Using an air compressor is another easy way to remove dust particles from the wood after sanding. This tool does the opposite of vacuum: it blows the sawdust dust away from the wood’s surface. If you have it around, try using it in the simple steps below.

The steps

Step 1: Set up the high-pressure air on your compressor, then switch it on

Step 2: Aim the compressor blower nozzle at an angle of about 45-degree.

Step 3: Allow the compressed air to flow out and blow away the dust from your sanded area.

Step 4: Give your surface a final wipe with a damp cloth.

Using a Tack Cloth

First things first: a tack cloth is a specialized sticky fabric designed to wipe loose dust, dirt, and lint from wooden surfaces before painting, staining, or any other form of finishing is done. Another common name for tack cloth is cheesecloth.

You can buy tack clothes from local hardware stores. However, you can make your cheesecloth if you’re interested in DIY. First, soak a 12-inch cheesecloth in a bit of Tung oil. Then keep it in a zip-lock plastic bag to prevent it from drying upon repeated usage.

The Steps

Step 1:  Fold the tack in whichever shape works for you, then use it to wipe off the dust in back and forth motions.

Step 2: Use a cleaner side of the cloth once one side gets clogged with accumulated dust. Ensure no dust is left lingering on the surface.

Step 4: Apply more mineral spirits to a cleaner part of the cloth and continue wiping. Repeat the process as many times as needed on every inch of your dusty wood.

Step 5: Use a clean, dry cloth to run passes on the surface. This is to ensure the wood is now free of mineral spirits and sawdust residues.

The wood might appear darker in color because of the number of mineral spirits used. But, as the wood dries, the original wood color will be restored.

Using Denatured Alcohol

You can use denatured alcohol to remove sandpaper dust from the wood surface. This alcohol evaporates fast, which means it won’t discolor the wood. It’s safe to use on any wood project idea.

The Steps

Step 1: Soak a clean cloth in denatured alcohol.

Step 2: Wipe the dust away from the wood using the soaked cloth. Use as much alcohol and several clean cloths as necessary.

Step 3: Ensure the last wipe comes clean, meaning all the sanding residues have been lifted, and the wood is ready for what’s next.
