Rust is a silent killer that slowly but surely destroys iron and steel without your knowledge. It's a serious problem that can cause massive damage to vehicles, suspension bridges and even warships.
Fortunately, rust can be treated with a range of products that can dissolve and remove stubborn rust stains on items like tools, cars and antiques. Some contain hydrochloric acid or phosphoric acid, while others use a fancy-sounding process called chelation to chemically break down iron oxide.
Most of these rust dissolvers work by eating away at the rust stain on your metal item, and some will actually break down the iron oxide so it falls off in little flakes, as opposed to turning into lumpy, reddish crumbles that need to be scraped off with an angle grinder or sandblasted.
In most cases, a metal part will only need to be submerged in the rust-removing liquid for a period of five minutes to a few hours depending on the extent of the rust. However, some alloys can be particularly prone to damage from the rust-removing chemical, so we recommend testing a sample first to make sure it doesn't have any issues before fully soaking it.
The Metal Rescue rust remover is designed to be used at room temperature, but it can be heated up to 150 degrees Fahrenheit to speed up the rust-removal process. If you're working outside in extreme temperatures, be sure to keep your rust-removing liquid covered. Otherwise, it can dry out and slow down its performance.
