Bolt Loosens Penetrate And Remove Rust Easily Twist The Bolts
Function:
This product is made of advanced formula, with the performance of penetrating and removing rust, cleaning and lubricating, inhibiting corrosion, and protecting metal. It can eliminate hinge noise, penetrate and loosen mechanical crankshafts, bolts or locks that are stuck due to rust. It effectively eliminates rust, corrosion, dust, graphite and grease, and forms a protective film to inhibit corrosion caused by moisture and many other chemical components. It can form and store a lubricating film on the surface of the parts.

Product Advantages:
- It has the functions of penetrating and removing rust, cleaning and lubricating, and can effectively act on various components.
- Suitable for various places such as homes, factories, offices, farms, ships, and vehicles; it can eliminate the noise of hinges, and perform penetrating rust removal, cleaning and lubrication on crankshafts, bolts, locks, etc.
- For rusted and stuck bolts, it can quickly penetrate into their gaps, helping to loosen them easily and reduce the difficulty of disassembly.
- Used for precision components such as crankshafts in vehicle engines, it can reduce component wear and extend service life while cleaning and lubricating.

Usage Method:
- Pretreatment: First, remove obvious stains, dust or loose rust on and around the bolt to ensure no large-area impurities block the spraying area.
- Spraying operation: Keep the can 10-15 cm away from the bolt, spray the loosener evenly to ensure the liquid fully covers the bolt surface and thread gaps. For severely rusted bolts, spray 2-3 times repeatedly with 1-2 minutes interval each time to allow the agent to penetrate fully.
- Loosening and follow-up treatment: After the agent penetrates for 5-10 minutes, use a wrench to slowly turn the bolt until it loosens. Wipe off any residual agent with a clean cloth after use to avoid dust contamination affecting subsequent use.
- Special scenario treatment: For small parts such as lock cores and hinges, spray the loosener on the moving parts, let it stand for a while, then move the parts repeatedly (e.g., turn the lock core, open/close hinges) to enhance lubrication and eliminate noise.



Precautions:
- Storage and environment: Store in a cool, dry place, away from open flames, heat sources (e.g., heaters, stoves) and direct sunlight to prevent the can from leaking or bursting due to thermal expansion. Keep out of reach of children and pets.
- Health protection: Ensure good ventilation during use; avoid prolonged operation in enclosed spaces to prevent inhalation of spray. It is recommended to wear gloves and goggles to avoid direct contact with skin, eyes or mucous membranes. If contact occurs, rinse immediately with plenty of water and seek medical attention if necessary.
- Material compatibility: Avoid using on corrosion-sensitive materials such as plastics and rubbers (e.g., some plastic pipes, rubber seals). It is recommended to test compatibility in a hidden area before use. Do not use on food-contact surfaces or high-temperature operating mechanical parts (e.g., engine parts during operation).
- Residue treatment: Wipe off residual agent promptly after use to prevent dust from adhering and forming dirt. Cleaning tools (e.g., extension tubes) should be cleaned before storage to avoid nozzle clogging affecting next use.
