However, in this article, you will learn about the simple and most effective process of removing rust from a table saw, and everything related to how to keep it away from rust.

10 Steps To Remove Rust From Cast Iron Table Saw: Use This For Long

There are some approved steps to remove rust from cast iron table saw that are easy and powerful enough. Follow these steps below to help keep your cast iron table saw safe from getting rust: 

Step-1: Gather Necessary Equipment

As a first step in removing rust from a cast iron table saw you have to collect some necessary equipment that will help you to get the job done smoothly. Below are the things you’ll need to do this:

  • WD-40 or mineral oil
  • Scouring pad
  • Paste wax
  • Clean rags
  • Protective gear ( Safety Gloves)

Step-2: Evaluate The Level Of Rust

Determine the depth of rust because surface rust is easy to remove but in the case of deep rust, you have to take a different approach. Deep rust is difficult to clean. This permanently damages the surface and prevents the table saw from becoming smooth again.

So, you need to evaluate the presence of rust and its levels before starting the final rust removal activities. Also, it is important to make sure that the tools you want to start working on are sufficient to remove rust from the table saw.

Step-3: Remove The Accessories From The Table

Things other than what you want to clean up become temporarily unnecessary. As you just want to clean the cast iron table saw rust, you should remove the rest except the necessary tools of the easy moment. Remove things like meter gauges, blades, and fences before you start work.

Start the main step of your work by removing the accessories from the table. You may know that rust causes the table saw to become uneven, so it is crucial to keep the entire space empty for proper cleaning.

Step-4: Remove The Light Dirt And Rust

Cast iron table saw carries rust as well as some dirt which should be cleaned. Also, you should remove first the light dirt or rust on the surface that can be easily loosened. The advantage of this approach is that you no longer have to pay attention to the places where the rust is easily removed and you will understand where more effort is needed.

Now the question is how do you clean light dirt and rust, right? Wash the whole table saw thoroughly with soap and water mixture. You can use a stiff brush to remove rust and dirt with pressure.

Step-5: Wear Safety Gloves

Take some precautionary measures before applying rust remover. It is harmful to come in contact with some rust remover. Some rust removers contain toxins that can cause sores on your skin as soon as they are applied. It is therefore advisable to wear protective gloves before applying any rust remover.

Wear goggles if possible. But how many precautions you should take depends on the chemical remover. For example, when using mineral oil you have to take less protection because it is not so harmful, although effective.

Step-6: Use A Good Rust Remover

Isn’t it better that you apply rust remover on a waterless metal? After cleaning, the table saw should be wiped so that no water droplets are left anywhere. Now apply a good quality rust remover to remove the rust residue. Although there are various options on the market, the application of WD-40 and mineral oil is still recommended.

When using WD-40 or mineral oil you need to apply it sparingly, and make sure that the rusted areas are evenly covered. When applying rust remover, be careful not to get into the motor. Anyways, leave the table until the remover works on it properly.

Step-7: Clean The Rust

When the rust remover is finished working on the table saw, now is the time to remove the rust. Since it requires some pressure to remove rust, you may want to consider using things like steel wool or sandpaper. Steel wool or sandpaper usually causes excess and ugly stains on cast iron products.

A scouring pad is the best solution to this task because rust can be easily removed by rubbing with it and there are no stains. To speed up your work, use a power sander that cleans the whole area very quickly and in a short time.

Step-8: Wipe Table Top Surface

If your scrubbing seems satisfactory, now is the time to remove the loose rust. Use something that will not scratch your table saw to remove rust. Remove these with a clean and soft rag.

After removing the rust, if the appearance of your cast iron table saw does not satisfy you and some rust remains, apply rust remover a few more times and wait a while.

Step-9: Use Of Wax

You certainly don’t want your hard work to fail, that is, the rust of the table saw will come back. It is important to make sure that the table saw is cleaned after going through so many steps so that it does not get rusted easily later. Waxing is a good solution in this case, but you have to be generous in applying it.

Different types of wax are on the market. You should choose a recommended and readily available wax. Most carpenters recommend using Johnson’s Paste Wax, which you can find at nearby hardware stores.

Step-10: Prepare The Table Saw For Further Use

After applying Paste wax well, the table surface and saw will look smooth and clean. Now it is ready to use. Re-attach the open blade to the saw properly and make sure it is stuck properly. Now bring back all the necessary accessories that you had removed from the table.

Although the methods of removing rust from cast iron table saw are simple, it is quite time-consuming. You have to spend a lot of time on this, otherwise, the rust may come back very quickly due to your unconsciousness.
