Preparation for Use
Before applying Liquid Wrench L106, ensure the area around the stuck part is clean and free of loose debris. Shake the can well for several seconds to ensure the formula is properly mixed and ready for optimal performance.
Application Instructions
General Application
Spray Liquid Wrench L106 directly onto the rusted or stuck component. Ensure thorough coverage of the affected area, allowing the penetrating oil to seep into threads and crevices. For best results, allow the product to sit for a period of time to enable deep penetration.
For Severely Rusted Parts
For extremely stubborn or long-standing rust, multiple applications over several hours or even days may be necessary. Apply the product, allow it to soak, and then attempt to loosen the part. If resistance is still met, reapply and allow more time for the formula to penetrate deeply. Patience is key for heavily corroded items.
Care and Storage
Store Liquid Wrench L106 Penetrating Oil in a cool, dry, and well-ventilated area. Keep the container tightly closed when not in use. Protect from direct sunlight, heat sources, and open flames. Ensure the product is stored out of reach of children and pets.
Troubleshooting
Part Remains Stuck After Application
If the part does not loosen immediately after the initial application, it indicates severe corrosion. Reapply Liquid Wrench L106 generously and allow a significantly longer soaking period. For deeply rusted components, this may require soaking for several hours or even multiple days with intermittent reapplications. Applying light taps to the part may also help the oil penetrate.
Product Not Dispensing
Ensure the included straw is firmly inserted into the nozzle. If the can is cold, the internal pressure may be reduced. Warm the can slightly by bringing it to room temperature (do not use external heat sources like open flames). If the nozzle is clogged, remove the straw and clear any obstruction.
