Assassin’s Creed Metal Hidden Blade Maintenance Guide: Rust Prevention & Scratch Repair Tips

You’ve finally got your beloved Assassin’s Creed Hidden Blade. But how do you maintain it to keep it shiny as new? And how to prevent rust?

This guide shares professional rust prevention and scratch repair tips for your metal Assassin’s Creed Hidden Blade.

Clean to Eliminate Risks: After each use, wipe the blade with a lint-free cloth dipped in neutral soapy water to remove fingerprint residue, then dry thoroughly with a clean cloth.
Regular Protective Reinforcement: Apply a thin layer of anti-rust oil (e.g., sewing machine oil) to the joints between the blade and wrist guard every 3 months. Add 1-2 drops of lubricating oil to the mechanical components.
Emergency Rust Treatment: If light brown rust spots appear, immediately wipe them with a 1:1 mixture of gasoline and engine oil. Alternatively, lightly sand the area with fine sandpaper dipped in water, then seal the surface with polishing wax.
Environmental Red Lines:
- Avoid storing in spaces with humidity > 70% (e.g., basements). Place silica gel desiccants in the display cabinet and replace them monthly.
- Coastal users should keep it away from salt-laden air and wipe it regularly with a dry cloth.

Corrosion-Proof Cleaning: Avoid acidic/alkaline cleaners (e.g., formaldehyde removers, white vinegar). Use a slightly damp soft cloth instead. For tough stains, use a small amount of neutral cleaner and dry immediately after wiping.
Coating Reinforcement: Every 2 months, apply a specialized metal protectant (e.g., car interior protectant wax) to the coating with a cotton swab, focusing on wear-prone areas like wrist guard edges.
Emergency Oxidation Treatment: If local blackening occurs, gently polish the area with a cotton swab dipped in toothpaste to remove the oxide layer, then apply protectant immediately.
Environmental Red Lines:
- Keep away from fumes of salt, detergent, etc. Store far from kitchens and bathrooms.
- Apply anti-rust oil every 6 months in dry areas, and every 3 months in humid regions—always clean oil stains thoroughly before application.

Stainless Steel: Use a soft wool wheel dipped in polishing wax to buff the scratch clockwise until the shine is uniform.
Zinc Alloy: Do not use sandpaper (it damages the coating). Apply a thin layer of matching nail polish to the scratch. After drying, gently wipe the edges with a soft cloth.

Stainless Steel: First sand the scratch in one direction with 400-grit wet sandpaper, then refine with 800-grit sandpaper, and finally polish with wax to restore the matte finish.
Zinc Alloy: Lightly sand the scratch edges with extra-fine wet sandpaper (1000-grit or higher), apply a specialized metal touch-up pen, and buff with wax after drying to reduce color difference.

Storage Tools: Use the original velvet bag for storage. Avoid direct contact with other metal collectibles. Place desiccants and anti-rust paper in the storage box.
Display Taboos: Avoid direct sunlight (it fades zinc alloy coatings and causes moisture buildup on stainless steel). Use a cork pad on the display stand to reduce friction damage.
Regular Activation: Extend and retract the mechanical structure 10-15 times monthly. Add 1 drop of lubricating oil to the slide rail to prevent spring aging and component jamming.

Cleaning Mistakes: Using steel wool or hard brushes (they scratch stainless steel’s passive film and damage zinc alloy coatings). Correct tools: soft cloths, cotton swabs, and extra-fine wet sandpaper.
Over-Maintenance: Frequent anti-rust oil application (attracts dust and forms sludge). Apply every 3 months for stainless steel and every 2 months for zinc alloy.
Poor Storage: Exposed display or long-term contact with plastic/leather (leather grease corrodes zinc alloy). Always store independently in a dry environment.
