No matter what the rust condition of your table saw, you can restore it.

2. Using Mineral Oil and WD-40

You can completely remove rust from your saw’s table with a scouring pad. However, it is not wise to use some extra lubricating oil.

Mineral Oil is the first thing that you should consider. You just need to use a little of this oil and apply it evenly to the surface of the table. You should use a sufficient amount of oil. Using too much oil can make it difficult for you to clean the oil.

After applying Mineral Oil, you need to scrub the saw’s table thoroughly until you can remove all the rust. After that, you need to use a dry towel to wipe off the oil.

You can also use WD-40 as a perfect substitute for Mineral Oil. However, if you choose WD-40, you will have to apply it regularly during the rust removal process. In general, WD-40 works well but is not as effective as Mineral Oil.

3. Using Naval Jelly

If you do not want to use Mineral Oil and WD-40, it is time to consider Naval Jelly. It’s a great choice for a severely rusted cast iron table saw top. However, Naval Jelly has a strong rust removal effect. Therefore, you need to follow the instructions for use to avoid pitting the table saw top.
