Directions for Use

Rust Free contains phosphoric acid. Always make sure to protect your eyes and skin from contact with this product. Contact with Rust Free may cause severe burns. Take special care to protect your material surface and the surrounding area as well. Always test Rust Free on a hidden area of your project before broad application.

Rust Free is designed to work best in temperatures above 70° F. It is recommended for use on all bare stainless steel or aluminum hardware. Rust Free may also be used on cast iron, fiberglass, chrome, tile, porcelain, vinyl, and cloth. Use Boeshield T-9 after cleaning to protect and preserve your hardware.

Cleaning Light Rust Stains

For light rust, apply Boeshield RustFree to a soft cloth and wipe off rusty and spotted areas. Avoid spraying directly on the surface to minimize the risk of spotting.

Treating Heavy Rust

For heavy rust, spray directly on the rusted surface and scrub with a mildly abrasive pad. Wipe off and repeat as necessary. Wipe your surface clean and repeat the process as necessary. Please note that using an abrasive pad on your Cable Bullet hardware will alter the machine finish.
