A:  Good question Susan. Rust-Oleum Krud Kutter The Must For Rust can be used on metal mechanisms. The Must For Rust penetrates into voids on the metal surface and dissolves rust and oxidation through chemical action. Small rust-inhibiting crystals are formed and become integral with the surface molecules of the metal to resist future rusting. Remove oil and grease from the metal to be treated. Rinse the metal to break the surface tension and wash away loose dirt. Apply the remover by brush, spray or by dipping. Disassemble units composed of movable parts before cleaning. Clean parts and allow to dry before reassembling. Always test on an inconspicuous area first. - Rust-Oleum Product Support 6

A:  Real aluminum will not rust so perhaps whatever they were using it on was not all aluminum. I think it can oxidize though in which case this product will work on that. If there were metal parts against the aluminum, like lug nuts that rusted they can stain the aluminum and this product will work on those stains. Here is what Krud Kutter says about aluminum: ALUMINUM/CHROME: Apply the remover to wet surface. Allow time to clean, then rinse away with clean water and buff dry with a cloth.

A:  Great question PJ! Rust-Oleum Krud Kutter The Must For Rust penetrates into every void of a metal surface and dissolves rust/oxidation through chemical action. Then tiny, rust-inhibiting crystals are formed and become integral with the surface molecules of the metal to resist future rusting. The corrosive agents attack these crystals instead of the metal. Once completely dry, the surface is ready for the next step, whether it be painting or welding, plating. No rinsing necessary. - Rust-Oleum Product Support 6

A:  Yes, it leaves a white residue, and will need to be cleaned prior to putting any coating on.

The Must For Rust does contain phosphoric acid, be sure to test first in a small inconspicuous area on the chrome plating to ensure favorable results. - Rust-Oleum Product Support 6

A:  It shouldn’t ruin the chrome you might have to use some chrome polish to bring the shine back after you use it

A:  I can not confidently tell you that it won't damage the chrome plating, however I can tell you that I removed rust from some chrome plated bicycle gears and components and it did not damage the chrome plating. This stuff works awesome!

A:  No, it will not damage any of the chrome that is still attached to the sockets.

A:  I found this stuff to be pretty ineffective and useless, even on lighter rust and that included soaking. Better stick with the wire wheel or try another product like Naval Jelly.

A:  Thank you for reaching out, Dave! How Rust-Oleum Krud Kutter The Must for Rust is applied is determined by the type of metal the surface is. This product can be applied with a sprayer if desired. - Rust-Oleum Product Support 3

Medium to light rust will be dissolved in 30 minutes or less, while heavier deposits may require a second application.
