Frustrated because your saw isn’t cutting as smoothly as it used to? Maybe it’s leaving burn marks on your wood or it just feels like you’re using more force to make those cuts.
This could be a sign that your saw blades are dirty. You see, things like tree sap, old wood bits, and even glue can stick to your blades over time. This gunk makes your blades work harder than they should, which isn’t good for you or your saw.
But don’t worry, we’ve got you covered! In this article, we’re going to show you how to clean saw blades properly. We’ll break it down into simple steps so you can easily follow along, no matter what type of saw blade you’re dealing with.
Why Clean Your Saw Blades?
Cleaning your saw blades is an essential part of maintaining their performance and longevity. When saw blades become dirty, whether it’s from wood resin, pitch, or glue build-up, they can lead to various issues. A dirty blade can cause burn marks on your cuts and result in splintered edges, compromising the quality of your work.
By regularly cleaning your saw blades, you can experience several benefits. Firstly, cleaning improves the efficiency of your blades, allowing them to cut through material with ease and precision. not only saves you time but also enhances the overall quality of your woodworking projects.
Secondly, cleaning extends the lifespan of your saw blades. Accumulated debris can cause unnecessary wear and tear on the teeth, leading to faster dulling and the need for frequent blade replacements. By keeping your blades clean, you can prolong their lifespan and save money in the long run.
Furthermore, neglecting to clean your saw blades can have safety implications. Dirt increases friction and puts additional stress on the saw’s motor, potentially leading to overheating or even motor failure. Additionally, a dirty blade is more likely to kick back, causing accidents and injuries.
When Should You Clean Your Saw Blades?
Here are some signs to look for that indicate your saw blade needs cleaning

Step-by-Step Guide to Cleaning Saw Blades
These steps apply to circular blades, but they can also be adapted for other types of blades.
Step 1: Safety Precautions
Before starting the cleaning process, it’s important to prioritize personal safety and prevent any damage to the blade or saw. Here are some tips to follow
- Ensure the saw is powered off and unplugged to prevent accidental startup or injury.
- Wear safety goggles and protective gloves to shield your eyes and hands from debris or cleaning solutions.
- Use caution when handling the sharp edges of the blade to avoid cuts or accidents.
- Work in a well-ventilated area to avoid inhaling fumes from cleaning solutions.
- Follow the manufacturer’s instructions for your specific saw and blade to ensure proper handling and safety precautions.
Step 2: Removing The Blade
While the process may vary slightly depending on the type of saw you have, here are general instructions for safely detaching the blade:
For Circular Saws
- Ensure that the saw is powered off and unplugged for safety.
- Locate the blade lock button or lever, usually located near the blade guard or handle of the saw.
- Depress the blade lock button or engage the blade lock lever to hold the blade in place.
- Use the appropriate sized wrench or tool provided with your circular saw to loosen the arbor nut, which secures the blade.
- Turn the nut counterclockwise (lefty loosey!) to loosen it, then remove the nut and any washers or spacers from the arbor.
- Carefully lift the blade out of the saw, holding it by the edges or using a rag or gloves to avoid contact with the teeth.
- Place the blade on a clean surface, away from any potential hazards, in preparation for cleaning.

Step 3: Cleaning the Blade
Now that your saw blade is removed safely, it’s time to get it clean and shiny.
Soaking in Cleaning Solution
Prepare a cleaning solution. You could use a commercial saw blade cleaner recommended by the blade manufacturer or any of the cleaning solutions we stated above.
Place the blade in a shallow pan or tray and pour enough cleaning solution over it to completely cover the blade. Let it soak for about 10 to 15 minutes. This soaking time helps loosen the tough residue.
Scrubbing the Blade
After soaking, take the blade out of the solution and use your brush to scrub it gently. You will notice the residue is much easier to remove now.
Pay special attention to the areas around the teeth and any notches. These spots can harbor more buildup because they often have more contact with the materials you’re cutting.
Rinsing
Rinse the blade thoroughly under running water to wash away all the cleaning solution and loosened debris.
