4.0 out of 5 stars It is not magic June 21, 2010
Size Name:8 Ounce|Verified Purchase
Good to soften rust on iron, however it is not magic, some sanding before and after applying is needed. Also, a second or third coat is needed to complete the job. Unable to remove the rust from a forged steel piece with all those pores.

5.0 out of 5 stars Worked as advertised September 15, 2011
Size Name:8 Ounce|Verified Purchase
I lightly srubbed the rust and other build up with a wire brush which made the scars on my Jeep look much better. I then dabbed the rust with Naval Jelly using a q-tip for application and waited for 10 minutes then rinsed with water. The Naval Jelly got rid of all of the rust on the first try except for the areas that I hadn't scrubbed enough lose rust and paint off of first. Bottom line, do adequate prep work and the stuff will work great but be forewarned that it can discolor the metal (which I was fine with as I was painting over it anyway).

3.0 out of 5 stars Didn't work for the job at hand May 25, 2012
Size Name:8 Ounce
I have used this stuff in the distant past and it worked. This time I had old rusty motorcycle parts to restore and it did nothing. I think this is more geared toward simple shallow surface rust. Multi-decade hard core rust is not what it's for. I'm going to try evapo-rust, if that doesn't work it's time for a glass bead blasting.

2.0 out of 5 stars Does not work November 4, 2012
By K. Ross
Size Name:8 Ounce|Verified Purchase
This product does not work as advertised. I tried several applications but still had to sand the surface to get the rust off. Save your money and buy sandpaper.

5.0 out of 5 stars Worked well on heavily rusted metal shelf. May 1, 2014
Size Name:8 Ounce|Verified Purchase
I used a drill brush to get off the rough stuff and score what was left. After doing so, I applied this and waited 10 minutes. After rinsing the shelf off with water, all of the rust was gone. Nice.

2.0 out of 5 stars Weak. Not sure it even did anything. April 17, 2014
By icawn
Size Name:8 Ounce
Tried to remove rust from the underside of a 3yr old mower. It is not magic and cannot "dissolve" rust as you might think. It's basically like using windex to wash your windows instead of water--no strength just polish. If you need it to remove REAL rust, you'll have to go elsewhere. Otherwise, this stuff will just help you polish off the rust dust after scraping/sanding it all manually.

It says to leave it on for 10 minutes. Maybe if I left a glob of it on there overnight it might have worked better, but it's too expensive but such a small amount to go that route.

4.0 out of 5 stars Packing not withstanding, very good product... January 30, 2014
By Scott
Size Name:8 Ounce|Verified Purchase
The box arrived a bit soiled, the cap wasn't on tight enough so some of it leaked out. Luckly the gel is thick so not to much was lost. The product is good, works well; did the job I needed. Would recommend putting in a ziplock bag before shipping.

I received it today, and discovered that it had slightly leaked into the box. The cap wasn't screwed on tight, and the safety seal was damaged.

5.0 out of 5 stars Great
This was a perfect product to remove the rust on my car and washed off leaving clean metal verses a black coating that many rust removers leave behind.

3.0 out of 5 stars Removes rust, very strong.
This does remove rust, but didn't work for what I was trying to do. It's certainly strong and I would highly recommend using thick gloves for the application. Read more
