4. Operating Instructions
This multi-purpose oil can be used for a variety of applications. Always apply sparingly and wipe away any excess.
4.1. Lubricating Moving Parts
Apply a small amount of oil to moving parts to reduce friction and eliminate squeaks. Common applications include:
- Door hinges
- Bicycle chains and gears
- Small motor bearings
- Tools and equipment
4.2. Penetrating Rust
For rusted bolts, nuts, or other metal components, apply the oil directly to the rusted area. Allow several minutes for the oil to penetrate before attempting to loosen the part. Reapply if necessary.

- Insufficient Application: Ensure enough oil has been applied to fully penetrate the affected area.
- Deeply Rusted Parts: For heavily rusted components, multiple applications over a period of time may be necessary to allow the oil to work effectively.
