How to use it:
- Choose a rust remover gel or spray specifically formulated for outdoor metal surfaces.
- Apply according to the manufacturer’s instructions.
- Let it sit for the recommended time (usually 10–30 minutes).
- Scrub with a steel brush or scouring pad.
- Rinse and wipe dry.
Safety tip: Always wear gloves and work in a well-ventilated area when using chemical products.
4. Seal the Surface with Oil or Wax to Prevent Future Rust
Once you’ve removed the rust, it’s important to protect the surface to keep rust from coming back.
How to seal it:
- Apply a thin coat of mineral oil, WD-40, or beeswax polish using a clean cloth.
- Buff until the surface looks shiny and smooth.
- Repeat every few months, especially in humid or coastal areas.
Why it matters: This barrier repels moisture—the main culprit behind rust formation.
Final Thoughts
