4. Setup and Preparation
- Clean the Surface: Ensure the metal surface to be polished is clean and free of loose dirt, grease, and grime. Wash with a suitable cleaner and dry thoroughly.
- Gather Supplies: You will need a clean applicator pad (microfiber or foam) and several clean, soft microfiber towels for buffing.
- Shake Well: Shake the Zephyr Pro-40 bottle thoroughly before each use to ensure the polishing agents are evenly distributed.
- Test Area: Always test the polish on an inconspicuous area first to ensure compatibility and desired results, especially on plated or coated surfaces.
5. Operating Instructions
Follow these steps for optimal results when using Zephyr Pro-40 Metal Polish:
- Step 1: Wipe On
Apply a small amount of Zephyr Pro-40 onto a clean applicator pad. Work in small sections, applying the polish evenly to the metal surface. Use moderate pressure to work the polish into the surface, focusing on areas with oxidation or dullness.
- Step 2: Let It Dry
Allow the polish to dry to a haze. The drying time may vary depending on temperature and humidity. This typically takes a few minutes.
- Step 3: Wipe Off
Using a clean, soft microfiber towel, buff off the dried haze with firm, overlapping strokes. Turn the towel frequently to a clean side to avoid re-depositing residue. Continue buffing until a brilliant shine is achieved.

- Applicator Care: Clean applicator pads and microfiber towels immediately after use to prolong their life and prevent cross-contamination. Wash separately from other laundry.
- Polished Surface Maintenance: To maintain the shine, regularly clean polished surfaces with a mild, pH-neutral cleaner. Reapply Zephyr Pro-40 as needed to address new oxidation or to refresh the shine.
