How to restore cast iron table saw top
To remove rust and restore the cast iron table saw top, you can do a few actions:
- Assess the condition of the cast iron table saw top
- Using Mineral Oil and WD-40
- Using Naval Jelly
- Using vinegar
- Protect your table saw even better
1. Assess the condition of the cast iron table saw top
Assessing the condition of the table saw is the first thing you must do. If the saw’s table has slight surface rust, this is not a serious problem. You can solve it quickly.
However, if rust stains have accumulated over a long period of time, this is really a challenge. Your table saw is unlikely to return to its original shape. Of course, you can still use it. However, its working performance is no longer high. Its accuracy will also decrease significantly.
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.
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.
4. Using vinegar
Vinegar is also very helpful in removing rust from cast iron surfaces. After you have applied the above methods to remove rust, you can add a little vinegar.
Wipe the surface of the table with the right amount of vinegar. It works to clean up small rust stains that may remain. In particular, it also has the effect of limiting new rust.
5. Protect your table saw even better
After you have successfully removed any rust, take good care of the cast iron table saw top. You can prevent the table saw top from rusting again with some commercial products like the Boeshield T-9 or Slipit. You can easily buy them at convenience stores. You can even buy them online.
