USE CASE: Application of Magica Rust Remover and Rust Blocker on U.S. Navy Surface Vessels

Purpose:
To remove surface rust stains and prevent short-term reappearance on exposed topside surfaces using Magica Rust Remover and Rust Blocker as part of general corrosion control and appearance maintenance.

Scope:
This SOP applies to cleaning and treatment of rust stains on non-structural, exterior areas such as stanchions, lifelines, bulkheads, non-skid decks, and painted metal surfaces.

Frequency:
As needed during weekly topside preservation walkdowns or prior to inspections and port visits.

STANDARD OPERATING PROCEDURE (SOP)

Required Materials:

  • Magica Rust Stain Remover (gel or spray)
  • Magica Rust Blocker (rust inhibitor spray or wipe-on)
  • Clean rags or sponge
  • Soft bristle brush (optional)
  • Freshwater spray bottle or hose
  • PPE: gloves, goggles, coveralls

Step-by-Step Instructions:

  1. Inspect & Identify
    • Locate surface rust stains, typically reddish-brown discoloration on painted or metallic surfaces.
    • Confirm that corrosion has not penetrated through the substrate (no blistered paint or pitting).
  2. Prepare Area
    • Rinse area with fresh water to remove loose salt and debris. Allow to dry.
    • Mask off adjacent sensitive equipment or electronics if needed.
  3. Apply Magica Rust Remover
    • Spray or brush a thin layer directly onto rust-stained areas.
    • Allow 3–5 minutes for the remover to react.
    • Do not allow the product to dry on the surface.
  4. Agitate (If Needed)
    • Lightly scrub with a soft bristle brush if stain is persistent.
    • Reapply if necessary for deeper staining.
  5. Rinse Thoroughly
    • Rinse the treated area with fresh water to neutralize and remove residue.
    • Wipe dry with a clean cloth.
  6. Apply Magica Rust Blocker
    • Once the area is dry, apply a light coat of Magica Rust Blocker to prevent rust return.
    • Let air dry. Product forms a clear barrier film.
  7. Document
    • Log the treatment area, date, and any follow-up needs in corrosion control records (e.g., PMS 4790/2K form or electronic log).

Safety Notes:

  • Always use PPE.
  • Do not use on hot surfaces or in direct sunlight.
  • Store Magica products in a cool, dry space away from ignition sources.
