Understanding the problem: Why does rust occur?
Rust is a relatively common problem that can occur in tools that are exposed to moisture or air for extended periods. Handsaws, in particular, are prone to developing rust because they’re often used outdoors or in damp locations. Rust is caused by a chemical reaction between iron and oxygen in the presence of water or moisture. Over time, this reaction can corrode metal, resulting in the formation of rust.
While rust doesn’t necessarily make a handsaw unusable, it can cause the blade to become dull and make cutting difficult. In some cases, the rust may cause the blade to warp or break, which could render the saw useless. Fortunately, there are steps that you can take to fix a rusty handsaw and prevent further damage.
Tools and materials you’ll need:
- Gloves for protection
- Baking soda
- Water
- Steel wool pads
- Silicone spray lubricant
Step 1: Removing the rust
To start, fill a bucket or container with warm water and add a few tablespoons of baking soda. Stir the solution until the baking soda dissolves. Soak the saw blade in the solution for at least 10 minutes to loosen the rust.
Next, use a steel wool pad to lightly scrub the rust away, adding more baking soda solution to the pad if necessary. Be careful not to apply too much pressure, as this could scratch or damage the blade.
Step 2: Dry the handsaw
Once you’ve scrubbed away as much rust as possible, rinse the saw blade with clean water to remove any remaining baking soda residue. Use a clean cloth to dry the blade thoroughly, paying special attention to any nooks or crannies where moisture might accumulate.
At this point, the handsaw should be rust-free, but it will likely be dry and lacking lubrication. To remedy this, apply a generous amount of silicone spray lubricant to the blade and handle. Spread the lubricant evenly with a clean cloth to help protect the saw from future rust and corrosion.
Step 3: Checking for damage
Once you’ve removed the rust and applied lubricant, take a close look at the saw blade to check for any damage. Look for any signs of warping, cracking, or bending which might prevent the saw from functioning correctly.
If you find any damage, determine whether it’s severe enough to prevent the saw from being used effectively. If the blade is severely warped or has cracks, it may be best to replace it.
Taking steps to prevent future rust
After you’ve fixed the handsaw, take steps to protect it from future rust by storing it in a dry location and avoiding exposure to moisture and humidity. If you’re using the saw outdoors or in a damp environment, consider using a protective cover or carrying case to prevent rust from forming.
You may also consider applying a rust inhibitor to the blade periodically to help maintain its condition. There are several products available that are designed specifically for preventing rust and corrosion in tools.
