Rust Free™ Rust & Stain Remover, Metal Restoration Cleaner for Steel, Cast Iron, Chrome, Tile & Porcelain, 8 oz Spray

Wow, this stuff is amazing! Spray the stuff on and it quickly cleans the rust off with a very light scotchbright pad (I used a glass surfaces/stovetop pad for gentile cutting). It really couldn't be easier! I haven't had any problem with the color of the cast iron getting damaged, which was my main concern. The bottle is kind of small, I wish I had bought a bigger bottle as I can see myself using this a lot. The speed at which it cuts through the rust is just amazing. What used to take quite a lot of time and elbow grease can be done is minutes with this stuff. For safety, I would suggest wearing some rubber gloves and wearing at least a paper mask. The spray does kind of get to your nose and I'm sure it's not good to breath. I can't imagine it's very good for your skin either, but it generally feels like a fairly safe product to use otherwise. Just use some basic common sense about handling chemicals.

It is Good stuff! I have usted in my boat since long time ago

I have used the Boeshield line of products for years. The Rust Remover is good stuff for light rust and stains. Use a different product for heavy rust. Unlike the gels this won't run you out of a well ventilated garage.

I used it on the top of an old cast iron Delta table saw with cast iron extensions. I was hoping it was all surface rust (which it did a good job on) but some of it was slightly deeper pitting. Ideally the RustFree would get at those pits and my hope was it would at least lighten them up, but they remained dark, even though most of the saw top is now rust free and shiny. You have to work very quickly wiping it on with some 360 - 400 grit sandpaper, and then wiping it off (all in less than a minute), and then getting on some acetone to get rid of any residue. Work quickly in small sections. Do not use soapy water like some recommendations say to neutralize the RustFree or you will immediately get more rust on cast iron. Right after the acetone, get the other Boeshield product (T9) on and let it sit overnight to protect it and prevent more rust.

I recently purchased a planer that was probably in a humid environment, or maybe had been left outside. So there was rust everywhere - I cleaned all the functional surfaces manually with sandpaper, steel wool, and elbow grease. Now I wish I had this "rust-free" stuff when I started the job, because I used it on the outside of planer just for cleaning up the look. I was guessing that I'd have some more sanding to do because the rust was pretty thick. But the small spot I tried it on looked great! So I sprayed down a whole section - the results were very impressive... Not only did it remove the rust, but you couldn't tell that the rust was there to begin with - I mean you can see the original machining marks that were covered up with a layer of rust! Where the rust was deep, it left the metal darker than the rest. So with a little steel wool, everything looks great! A couple of catches about this item - It smells BAD BAD BAD! It made me cough something fierce when I inhaled just a bit. WEAR A RESPIRATOR! It made my eyes burn when I had my respirator on, so I used goggles and a big fan (hard to control the spray when the fan is going - but do it anyway!) Don't forget gloves because your skin will begin burning! Heck, get a disposable clean-room suit, they're cheap! The other catch - it leaves a very sticky, gummy surface. Like you let honey dry for a month. So I cleaned up with some solvents (acetone breaks it up nicely). All in all, I'm very happy with this product, as it did exactly what I needed - better than what I thought. I'm glad I don't have to use it everyday because it is toxic. I've already recommended it to friends who have rust issues!

Absolutely the best I have ever used. I've used it 3 times now and I highly recomend it. It was recomended to me by 2 of my You Tube Favorites and they are both great channels that I trust. Colton and Matt the Scrap Whisperer.

Does an OK job removing rust, but the longer you leave it in your metal, the more likely it will discolor it. I used my table saw as a flat place to do a glue up and I used way too much glue, which soaked through the heavy duty paper I had put over the saw top in a couple spots and caused some minor rust. This did an OK job of removing the worst of the rust, but left some residue on the table surface. I made the mistake of spraying some more on and letting it "soak in" in an attempt to remove more of the rust. I ended up with a much bigger mess than what I had originally. I had tested this on my saw before as recommended and it didn't leave any marks on the steel, so I was a little surprised at what it did to my table saw. I would have been better off just using some steel wool and WD-40 to remove the rust.

This cleaner works great but the fumes will gag you. I recommend using in a ventilated area. I used it in my attic HVAC drain pan and suffered through the fumes. It was worth it though. The pan looked great afterwards. Also, make sure you have plenty of rags you don’t want to keep.

Efficace Ça enlève vraiment la rouille!!
