Never let someone barrow your table saw. I have a nearly new saw, and I made the a fore mentioned mistake. The saw top now has a bit of rust on it. It is cast iron. I have read several articles and noted many products are listed. This is my question. Years a go while still farming, we had plow shears that would rust if not protected. We put Coke Syrup on these shears. It removed as well as protected the shears from rust.
I realize this is going to be a bit sticky, but I just wondered if any one else has ever used this on a saw table top. It will clean off very quickly with vinegar. I do not want to put something on the top that is going to create more damage. It looks like the rust is not deep and will clean with elbow grease and a rust remover. Thanks, any thoughts are welcome.
I think that the Coke Syrup would work just fine in that it would keep air and mositiure from coming into contact with the cast iron. The problem however would be adding it and removing it on a regular basis, but for long term strorage it should work. In many cases however one's TS is used on such a regular basis that the syrup removeable every few days or so would get to be a real pain in my opinion.
A year or so ago a tornado took part of the roof off the tin building that my shop tools are in. Everything was drenched and all of the cast iron tables turned to solid rust. At first I was horrified. Then I realized that the rust probably was only surface rust as the time element was short. Sooooo I took a chance and put some 220 grit paper on my palm sander, didn't own a ROS at that time. I then put a liberal coat of WD 40 on the cast iron surfaces and went for it, the surface rust came off alright, it took some time but the surfaces on the TS, BS and jointer looked like brand new after a fashion and I was able to breath easy again.
A short time later I was advised to wax the cast iron with Johnson's wax, which really id work well for me as far as being able to easlly wipe off any dirt and grim that settled on the surfaces.
I have used up most of that first can of wax and it has almost turned to a liquid, probably due tot he heat in the shop during the summer. It no longer has the effect on the cast iron as it did, it's time to buy a new can of wax and I will do that soon.
I do try to keep the cast iron covered with some sort of cloth sheets when the tools are not in use, this minimizes the grit and grim from accumulating, and the surfaces are easily wiped clean or the air hose will blow what little grit may have settled even with the coverings in place. My shop is in a relatively dirty environment, farm land all around and lots of wind here in West Texas.
You will probably get several good answers to your thread, most of which will be more sophisticated than mine, I'm just relating my personal experience for what it's worth.
Do let us know how things come out, I doubt if your TS is going to be hurt much from the rust on it's table.
