Cleaning your hand saw blade using a blade scraper is vital in removing all rust residues on the surface of your blade.

Steps to follow when cleaning your hand saw blade

There are various methods of cleaning and getting rid of rust, grime and dust from your hand saw blade. Here is how you can easily clean your blade using home remedies;

1. Removing the handle

Before you start cleaning your blade, you should remove its handle. By doing this, you will be able to expose the entire blade to the cleaning process. Furthermore, during this time, you should assess whether the bolts are in good condition or need to be replaced once you are through with cleaning.

2. Electrolysis

Electrolysis is one of the best methods of rust removal and can be used on various metal tools at home. When conducting electrolysis, ensure that you are in a well-ventilated area and free from open flames. Here is how you can perform electrolysis at home;

  1. Fill a bucket with warm water
  2. Per gallon of water, you should add one tablespoon of baking soda and stir to dissolve.
  3. On the positive lead, attach iron metal and deep it in the bucket with baking soda solution. You should not place clips or clamps in the solution to prevent them from rusting.
  4. On the negative clam, attach your rusted hand saw blade and deep into the baking soda solution in the bucket. While inside the solution, ensure that positive and negative leads are not touching.
  5. Once you are done setting up, you should turn on the power. Once the power is on, the negative side where the rusty blade is will start to bubble and fizz. The bubbles are hydrogen gas escaping electrolysis. During this process, the rust will become negatively charged ions and separate itself from the blade. Afterwards, the rust will move to the positive side of the electrolysis where it will be deposited. Often this process takes approximately 30 minutes; however, it will depend on the amps of electricity being used.
  6. Once you are through with electrolysis, you can use a wire brush in removing the remaining rust or debris. When done, you should consider treating your hand saw blade with oil or rust inhibitor to prevent rusting in the future.

Importance of cleaning a hand saw blade

Friction is the enemy when it comes to woodworking which means keeping your tools such as a hand saw blade free of pitch and clean is very critical.

Maintaining your hand saw blade clean is essential, especially when dealing with pitchy softwoods. When resin and pitch build up in your blade, it will affect your woodworking experience since it causes a build-up of heat, drag and vibration. Furthermore, this will affect the quality of the cut; therefore, cleaning your blade will help you avoid such situations.

Maintaining a clean hand saw will ensure that you have peak performance in woodworking. Getting rid of materials that dull your blade is essential in improving your performance. When rust accumulates over time on your blade, it can make it lose its strength. Whenever a hand saw blade has any deficiency, it should not be used until it is repaired.

Protecting your hand saw blade from rusting

Protecting your blade from rusting is vital in improving its performance. Once you clean your hand saw, the lasting you would want is it to rust again; therefore, protecting it is essential.

Keeping your blade dry is the first thing you should consider. Always store it in a dry toolbox or place. Furthermore, using lubricants such as gun oil or WD 40 is critical in protecting your blade from rusting. The oil or lubricant helps in preventing oxygen from coming into contact with the surface of your blade.

Always maintain the wood handle of your blade by rubbing it with boiled linseed oil. When the wooden handle is dry and scratched using linseed oil is the best method of protection it. You can use a dry rag to rub the oil on the handle. Moreover, you can unscrew the handle when it appears dirty or rusty and cleans it all round. Often dust particles build in the wooden handle; therefore, getting rid of it is essential.

Conclusion

Once you clean your hand saw blade, you should always store it in a dry place and you should always avoid high humidity or excess moisture to prevent it from rusting. Furthermore, you should often clean it to maintain excellent performance. When sap and pitch accumulate, it will lead to increase heat and friction, which will affect your blade’s performance.

When cleaning using a wire brush, you better use it gently since it might lead to severe damage. However, using brass or nylon brush as a substitute is more considerable. You should always avoid overheating your blade while cutting wood​ since it can lead to a thermal crack in carbide. The crack might cause fragments to come off the blade and possibly injure you while operating.
