Metal Blast - 1 Gallon - Rust Remover & Metal Prep, Cleaner & Conditioner for Superior Adhesion, Eliminates Grease, Contaminants & Corrosion

WOW! I have never used a rust product before, but I have an old 1981 vespa that needed some touching up - both where paint had rusted and the entire muffler. I sprayed this on and drank a beer, expecting to come back and scrub the heck out the rust. Without even touching it, the rust disappeared and revealed clean steel. I was astonished. I didn't scrub it at all and had amazing results. It didn't smell too caustic or anything, and some got in my eye from the wind but it didn't hurt or need any attention.

This rust remover works great. Highly recommend.

I had one bad spot on my beater truck frame, used this stuff to try to get rid of the rust so I could fix it. (Ignore the garbage weld) It works great! It ate most of the rust in a few minutes, however it dries quickly and you have to keep it wet for it to work. It also is super hard to wash off. I used a pressure washer and a rag 6 times just to wash the chemical off enough so i could paint it. Other than that, I highly recommend.

I was looking for something that would take the rust off my white patio furniture. This is the real deal. Have been using on all sorts of rust. Had to buy more. Spray on and wait a bit. So easy.

Product definitely works, and vigorously! Upon dipping a rusty knife tip into the solution just covering the rust, it began bubbling, attacking and dissolving it. Foolishly and tragically, the rusty knife that was my late dad's from the 1960s or so I left in the solution overnight, and now I have a pitted, partly dissolved away stub. Salvageable, I can probably grind it down into a serviceable if shorter blade, but dang it, that's what I get for trying to be industrious when tired! Anyway, great product, does what it claims for sure, the blade when I checked it before bed was almost devoid of rust altogether.

Didn't work as advertised

This works well on minor rust. For heavy rust, need to wrap/set a towel on the rust and spray it on to keep product working on the rust. First time using it, happy with the purchase due to the good reviews.

I used this to help clean up some excessive rust on my car's body. For context, my 2005 Ford Escape has rust on the fenders by the wheel wells that was rusted almost completely through the metal. This was able to clean up most of that rust with relative ease. Many surface rust spots cleaned up much easier than my rusted out holes and broken bits but great quality for the price I paid. This also cleaned up my rust stains on other portions of paint and metal, adding to the overall cleanliness look. Caution: Ensure you clean the area properly after use.
