Rust Free bubbles as it penetrates
and breaks down the rust. It also
emits a strong odor, so work in a
well-ventilated area.

about 5 minutes.

Boeshild Rust Free

Boeshield Rust Free attacks rust with a phosphoric-acid formula, so when applying it wear latex or rubber gloves to prevent skin burns. Spray Rust Free onto affected areas, allow it to penetrate for 30 to 60 seconds, and then scrub with a scouring pad or steel wool, middle photo. (If left on more than a couple of minutes, Rust Free will create dark stains that could become permanent on cast iron.) Repeat if necessary. This product removes the rust as well as dark stains, but it dulls the patina, bottom photo. If you're cleaning only part of the top, this dull look will be noticeable.

Been using Johnsons paste wax for years now, just wipe on a thin coat and leave it. One winter the temperature jumped up from freezing to 60 degrees F and all my cast iron tops were sweating. That time I used Boeshield T-9 and let it dry. Saved everythibng from even the slightest rust.

Although WD40 is a great lubricant, it should never be used to inhibit or prevent rust. Check the ingredients and you'll find it contains hydrogen and what do we get when we mix hydrogen and air? H2O of course. when that comes in contact with bare steel such as a saw blade, you get FeO2 otherwise known as rust. Try spraying a light coat on a saw blade and leave it where it's exposed to regular unconditioned air over night. The next morning you should see a light coating of surface rust.

A couple years ago I was restoring a bunch of old planes. I bought a couple gallons of Evapo-Rust and put the plane parts in a bath for a day or two. Then polished off the scale with steel wool or a dremel tool brass brush. Nice look and doesn't remove all the patina.

I never much cared for T9. It didn't seem to protect all that well and made my saw table a bit sticky. I recently read about CRC's 3-36 Multi-Purpose Lubricany and Corrosion Inhibitor and I've become a believer. Spray it on, rub it around so every things is wetted, and let it dry.

Good luck finding anywhere to buy Top Saver! As far as I could determine, there is only one company that sells the product in a separate bottle and they have not had any available for the last two months. You can find kits that contain Top Saver, but then you have to buy other products that come with the kit. Top Saver works great, I would love to be able to buy more and hope that maybe someone out there knows where it is available!

Whenever I get rust on my 66 year old cast iron table saw top I use WD-40 & a piece of fine grit (300) emery paper. It leaves a fine protection on my saw when I'm done.
