Boeshield RustFree Rust and Stain Remover, 8 oz

It works very well but you need to be deliberate with your application. It will affect nearby surfaces so be mindful when you 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.

This stuff is amazing!

I used this to remove surface rust on my cast iron table saw, and it works great! I sprayed the affected areas directly, let it sit for about 45 seconds, then with medium pressure, I scrubbed with the green side of a Scotch-Brite pad. The rust began to come right off. I immediately wiped up the area with a clean rag. For the stain removing portion, it did not work so great. I have a stain on my cast iron table saw top that the Boeshield RustFree and Stain Remover was unable to remove. To be fair, I wasn't really expecting it to remove the stain completely, as it seems once you get a stain on the cast iron top, you aren't ever going to be able to get it out without milling down the surface of the table. For those who are purchasing this to remove cast iron table saw stains, this might not work for you. It is possible I didn't let the product soak enough on the table, so your results may vary. I might try for a longer soak time in the future. This is a great product overall though, and I plan on purchasing more as my supply runs out. As far as rust removal goes, no other product I have used works better than this. I recommend you give this a try as well.

Save time and money instead buying individual products. Sorry, but I have no patience with two products, this is the way to go.

Works as advertised. Removed the rust on my cast iron tablesaw top, which had a fine coating of rust after 10 months of storage before using.

A total waste of money. Doesn’t remove rust as claimed. Completely ineffective. Deserves ZERO stars. Use Bar Keeper’s Friend instead. It works MUCH better and is MUCH LESS EXPENSIVE.

Great solution for PM work on my F250 and fifth wheel RV. Just a little goes a pretty long way and definitely eases the little bit of wire brushing needed after the application!

Great product
