Super Rust Breaker
Zep Super Rust Breaker is the solution for your toughest rust frozen bolts. It’s effective for many challenging rust problems, including: nuts, bolts, couplings, fittings, hinges, locks and other components. Its deep freezing action rapidly reduces the temperature of the area sprayed down to as low as -40 degrees Fahrenheit. Shrinkage from this sudden temperature change causes micro-cracks between the rusted surfaces. Rust eating active ingredients then penetrates deep into these micro-cracks to attack rust and loosen seized connections. The spray valve allows use in any position and access to hard-to-reach areas. Ultra Low VOC content, Nonconductive to 33,000 volts.
- Contains rust eating additives
- Deep freezing action cracks rust
- Penetrates into cracks to attack rust
- Ultra low VOC content - 50 state compliant
Directions & Pro Tips+
NOTE: Sudden temperature drop can result in "thermal shock" which may cause crazing of some plastics and paint. While appropriate for use on many plastics and painted surfaces, always test in an inconspicuous area before general use. Accumulated vapors from this product may reach ignition conditions in confide spaces. Always use with adequate ventilation.
- Insert extension tube into the spray tip.
- Shake can well before use.
- Limit the spray to the surrounding area as much as possible to achieve maximum temperature differential.
- Wait 30 seconds to allow the rust eater to penetrate deep into the micro-cracks and attack the rust.
- Tap joints lightly with rubber mallet.
- Loosen and/or remove the seized part.
- Very severely seized parts may require power tool assistance.
DANGER: Flammable. Eye and skin irritant. Contents under pressure. Keep out of reach of children.
