Blade & Bit cleaner works ok, but other products are cheaper and probably work better than T-9 and Rust-Free
on June 5, 2014
Update 2014-07-21: I have to say I'm more than a little disappointed with the T-9. After less than 2 months, one of the cast iron wings on my brand new table saw started showing signs of surface rust--it looked like a big reddish stain covering about 1/4 of the surface. I stripped the wax and T-9 off with mineral spirits, and continued to scrub for a while with a rag but the rusty-looking stain wouldn't go away so I thought I'd try the Rust-Free. That was a mistake. Sure, it got rid of the rust, but it turned the formerly shiny, polished table saw wing into a blotchy gray mess. I'd recommend only using Rust-Free on heavily-rusted items, and lightly sanding other rust with steel wool or 2000 grit sandpaper.
I bought this value pack because it wasn't much more than just getting the T-9.
Boeshield T-9: Numerous people in online woodworking circles recommend Boeshield T-9 as an anti-rust coating for cast iron tools. You can either spray it on and wipe it off for a thin coat, or spray it on and leave it for a thick coat. After each coat, you have to let it dry overnight. The finish after curing is a bit tacky, so you need to apply a coat of non-silicone wax over the T-9. I ended up putting heavy coats on the sides of my table saw top and extension wings, and two thin coats over the top. After putting a coat of Renaissance Wax over the top surface of the table saw, the surface is nice and slick again.
Blade & Bit cleaner: I was using some of the milky white eco-friendly mineral spirits to clean the grease off various parts of my new table saw, including the saw blade. It worked ok, but on the saw blade it didn't do very well around the teeth. I did a second and third pass with the blade & bit cleaner, and the blade seemed a lot cleaner. I'll probably also try this out on my circular saw blades since they're pretty gummed up.
Rust Free: I do NOT recommend using this for light surface rust. If you apply Rust-Free to a nicely-polished cast iron table saw top, it will ruin the finish. You're probably better off with just a light sanding.
