Hoppe’s No. 9 Moisture Displacing Lubricant is a specialised gun care spray designed to drive out moisture and protect firearm metal surfaces from corrosion, rust, salt, and wear. Packaged in a convenient 100 ml aerosol can, this product offers quick-penetrating protection and light lubrication after cleaning or field use — helping extend the life and reliability of your firearms and metal equipment.
Key Features
Moisture-Displacing Action:
• Penetrates tight spaces to push moisture away from metal parts, helping prevent corrosion before rust starts to form.
Multi-Function Protection:
• Not only displaces water, it also cleans, lightly lubricates, and shields surfaces against environmental damage — reducing friction and wear where metal contacts metal.
Fast-Drying Aerosol:
• The spray delivers an even protective film without leaving a sticky residue, making it ideal for use right after range sessions or in wet conditions.
Compact & Easy to Carry:
• The 100 ml size is range-bag friendly and easy to keep on hand for quick maintenance whenever needed.

Performance & Practical Use
This spray is designed for use after cleaning your firearm or during field use where damp conditions or humidity could lead to corrosion. The moisture-displacing formula reaches into crevices and contact points to expel water and contaminants while leaving behind a protective film that helps slow oxidation and wear.
Unlike heavier oils, this lubricant sprays on easily and dries quickly, which helps keep mechanisms like actions, rails, and linkages moving smoothly without gumming up. It’s particularly effective for protecting firearms stored in humid climates or after wet range sessions.
Best Suited For
✔ Immediate protection after cleaning or shooting sessions
✔ Shooters who want to guard against corrosion and moisture damage
✔ Firearms exposed to rain, humidity, or salt air
✔ Light lubrication and rust prevention in between deep maintenance cycles
User Tips
Use After Cleaning:
• Apply after your usual solvent cleaning products and before heavier oiling — this spray helps seal out moisture that could cause rust.
Spray Sparingly:
• A light, even coat is usually sufficient — excess lubricant can attract dust or debris.
Ventilated Application:
• When spraying, work in a well-ventilated space or outdoors to ensure safe dispersal and drying of the aerosol.
Regular Maintenance:
• For best protection in adverse climates, reapply periodically during extended use or storage.
