When the saw blade in your electric saw starts to burn through workpieces or cut horribly, three things should cross your mind. Either the blade is dull, dirty, or you are feeding stock too fast. Also, wet lumber, especially hardwood, can cause the blade to cut badly or cause kickback.

If the blade is dull, just sharpen or replace it, and if it is dirty, clean it or install a new blade. But if the burning is happening because you are pushing the stock too aggressively, you need to change how you do it. It is time to be soft with your saw. Start pushing the workpiece slowly through the blade and trust me your saw will thank you. You will also notice an improvement in the quality of cuts and the noise will also reduce.

In this article, I will focus on how to deal with a dirty saw blade effectively without breaking the bank. You will learn that replacing or resharpening a blade is not always the solution to a bad blade. Sometimes all you need is to deeply clean the saw blade to restore its sharpness.

#2. Clean with oven cleaner spray

Some oven cleaners are not only useful in the kitchen but also in the garage for cleaning equipment and saw blades. These oven cleaners cut through grime, pitch, resin, and carbon build-up on saw blades and other shop equipment just like they do on greasy ovens.

One of the best oven and grill cleaners you can use as blade cleaner is the Heavy-Duty Easy-Off oven cleaner. It contains a strong formula that cleans gummy surfaces within minutes.

Tpically, cleaning dirty saw blades with oven cleaners involves the following steps:

  1. Remove the circular saw blade safely from the saw tool
  2. Spray the oven cleaner generously on both sides of the blade. Let it sit for about 5 – 10 minutes to dissolve away the gunk.
  3. Wipe off the gunk with a damp sponge or piece of cloth. However, if you still see stains on the blade, spray the grill cleaner again and scrub lightly with a soft bristle brush.
  4. Spray dry lubricant to protect the blade from rusting and to reduce buildup.

Note: The only downside of some oven cleaning sprays is that they produce choking fumes. So, make sure you wear a mask and if possible, work in an open area or clean intermittently to minimize exposure. Also, most oven cleaners do not have anti-rust properties.

#3. Use WD40

WD40 is not only good for penetrating stuck bolts and nuts but also for cleaning equipment parts. You can use it to remove crud from a saw blade to make it cut more smoothly.

To clean a saw blade with WD-40, just squirt a sufficient amount the surface of the gunky blade and let it sit for about 10 minutes. Then wipe off with a rug. However, if the gunk is very stubborn, use an old toothbrush to scrub the grimy spots then wipe off with a rug.

Baking soda has a property that makes grime and grease dissolve in water. This makes it one of the most common ordinary household cleaning agents for porcelain and metallic surfaces. You can also use it to clean the saw blade of your table saw when it gets too dirty to cut clean edges. However, this DIY blade cleaner does not do a perfect job as the other 4 blade cleaning methods.

  2. Mix hot water and baking soda. Mix baking soda with hot water to form a thick paste.

  4. Scrub the blade surface with a brush. Use a scrub brush or a sponge to scrub off stains from the blade gently. Be careful not to scratch the paint.
  5. Rinse off with water. Use clean water to wash off the gunk.
