How To Clean Circular Saw Blades

Keep the following handy:

  1. Water
  2. Soap or detergent
  3. Soft Wired or Plastic bristle brushes
  4. Container or pan

The entire procedure of cleaning circular saw blades is broken into five easy steps.

Step #1: Remove, Brush, and Soak the Blade

Follow the manual procedure of removing the circular blade from the ardor shaft with caution. You need to clean the nuts and screws pulled out from the shaft. You can refer to this detailed guide to learn how to remove the blade from the ardor.

After removing the blade from the shaft carefully, take a large pan or container to put the parts of the disassembled blade. Move on to pre-soak the parts carefully. Once soaked, use the soft-bristled brush to rinse it thoroughly. This step removes all the dirt accumulation.

Always use plastic or rubber gloves while handling the blade. The blade may be blunt, but it still has the sharpness and edge needed to inflict minor cuts and wounds. Wear gloves while rinsing the blades as well.

Step #2: Pour Laundry Soap or Detergent

Estimate the amount of soap or detergent needed and pour it into the container with blades. You don’t need to buy any particular cleaning detergent. Your everyday laundry soap or detergent cleaning agent will suffice.

Stir it using the brush used for cleaning earlier. It would be best to let the soap settle over the metal surface of the blade for ten to fifteen minutes.

Remember not to stir the entire mixture using fingers as the blade edges are sharp and can cause cuts. Even while using a brush, you do not have to mix them excessively — a turn or two is enough.

Step #3: Scrubbing Time

Wait for half an hour and start scrubbing other components using a gentle brush. It is pretty effective on the metallic edges as they don’t cause the wear and tear impact.

Use a soft brush to reach all nooks and crannies of the mechanical blade with so many edgy parts and twisted anatomy. Brass brushes are best for cleaning such large equipment.

The soft texture of these brushes is helpful to minimize wear and tear damage. It is a one-time investment as they last longer.

Step #4: Dry the Metallic Surface

After scrubbing off the accumulations, the next step is to dry the metal surface of the blade. Take it out of the container and wipe off the liquid using a piece of dry cotton cloth. You can even use tongs as an alternative.

Wipe the excess water off its body and place the blade and its screws in the sun. If you don’t get much sunlight, dry it off using a ceiling fan.

Water and steel are known to be “archnemesis.” Thus, it is crucial to dry the metallic blade properly. As the blade runs on electricity mostly, it is essential to dry the edges. A wet blade is hazardous for everyone.

Step #5: Assemble All the Parts

Go through the user manual once again to re-assemble the blade.  Re-assemble and then run a quick check to see whether it is working correctly or not.

Don’t worry if you encounter an issue or if it does not work. Go through this video tutorial that will guide you on re-assembling circular saw blades.

Additional Tips

In some cases, just cleaning a blade may not be enough to fix the bluntness of its edges. Thus, you will need to sharpen the edges of the blade so that it works properly.
