How To Remove Rust From a Circular Saw Blade In Easy Ways

Vinegar or acetic acid is a strong cleaning agent. It may take time but this way is 100% effective in removing saw blade rust from the circular saw. In this rust removal process, you need some materials like a tray, metal brush, and white vinegar.

First of all, take a small amount of white vinegar according to the size of the blade. Now, as it is impossible to clean the blade with the saw, unplug the saw and remove the blade.

Next, soak the saw blades in the white vinegar solution for a couple of hours. For big and heavy saw blades, you can pour the vinegar on the surface rust. We suggest you soak it for the whole night for better results.

Once the saw blade is dipped for hours, take it from the vinegar. After taking the blade, the rust ends up like liquid sediments. To remove the rusty mess, scrape the saw blade with a metal brush or steel wool. 

As a metal brush can easily clean the rusty surface, use the brush for a few minutes. As soon as you remove this rust, use a paper towel to wipe this rusty mess.

Finally, you can use a wool brush for cleaning circular saw blades. If the circular saw blade remains rusty, repeat the whole process one or more times to get better results.

Using baking soda needs a little bit of effort compared to cleaning with white vinegar. But, it will take only a few hours to remove rust. For the cleaning process, you need materials like a bowl, tray, soda paste, toothbrush, cloth, and metal brush.

Now, as you need a paste to clean the rusty saw blade, take the baking powder and baking soda in a 1: 1 ratio. Take the amount according to the size of the blade. Next, add a small amount of water to make a thick paste of soda.

Then, take a toothbrush and apply the paste to the rusty areas of the saw blade. If the blade is thick and small, you can pour the paste on the whole blade and spread it. This paste will take around one hour to remove the rust from the saw blade.
 
After one hour, scrape the saw blade with a metal brush or steel wool. Use the metal brush until you get the metal of the sharp blade. Once you find the metal, rinse the blade with clean water.

Finally, use a dry cloth to wipe out the excessive paste. As you’re using a paste, some of it may stick with metal. You can also use a little bit of oil to lubricate the blade. As a result, the blade will be safe from future contamination

WD-40 is a non-toxic and biodegradable rust protection formula that is ideal for removing light rust from the saw blade, razor blade, or knife. Using this chemical solution is simple as it comes in a spray bottle.

But, it may take a couple of hours to remove the rust. Before going into the process, pick materials like a bottle of WD-40, a metal brush, and a cleaning cloth.

Let’s spray the WD-40 in the rusty areas first. Next, use a metal brush or fine steel wool to remove the rusty mess from the blade surface and arbor hole. Repeat the process a few times with a break of 15-20 minutes. It is better to repeat than go for a long spray. Once you remove the rust, clean it with a clean cloth.

If the rust is stubborn even after multiple sprays, you can take liquid WD-40 in a bucket or tray and drip the blades on it. Take out the blade after 1-2 hours and clean it with a cloth.

With such cleaning, stubborn rust will be removed easily. As WD-40 is a rust protection formula that works to prevent rust, it can keep your blade safe from further risk of corrosion.
