Rust Removal with Vinegar
Media blasting and electrolysis are common methods for rust removal from metal, however these treatments require professional application. Specialty products and kits are available for do-it-yourself jobs, although many on the market are expensive and caustic. But anyone who wants to remove a rust stain should take advantage of a readily available pantry item. Household vinegar can be just as effective as a specialized rust remover when it comes to reinvigorating metal. In addition to being an economical option, vinegar is an all natural and non-toxic rust removal solution. And since it is not caustic to the skin like many rust removers, it is easy to apply.
To remove rust with household vinegar, spray it directly onto a rust stain and scrub it into the surface. Spray the area again with vinegar and leave it alone to soak for 20 to 30 minutes. After the vinegar has penetrated the rust, the stain should lift as the solution is wiped away.
Alternatively, smaller rusted objects can be steeped in vinegar for at least 20 minutes and wiped clean after they’re removed. Once the rust stain has been removed, swab the area with rubbing alcohol or paint thinner to prevent rust from developing again.
