LIQUI MOLY Door Lock Care & De-Icer (1528) – Professional Lock Maintenance Spray

Purpose and Specifications

LIQUI MOLY Door Lock Care is a specialized lubricating spray designed to keep door locks, ignition cylinders, and mechanical side mirrors operating smoothly year-round. This 50ml aerosol spray reduces friction between moving parts, prevents rust formation, and thaws frozen locks in winter conditions.

• Reduces friction and wear: Keeps locks moving freely without sticking or grinding
• Lasting corrosion protection: Prevents rust and oxidation inside lock mechanisms
• De-icing action: Thaws frozen door locks in cold weather
• Safe on all surfaces: Does not damage plastics, rubber, or paint finishes
• Container: 50ml pressurized aerosol bottle

When to Use / Replace?

Apply this spray when your door locks become stiff, sticky, or difficult to operate. Use it preventatively before winter arrives to protect against freeze-up. A single 50ml bottle typically treats multiple locks and lasts several months with regular use. Reapply every 3–6 months or whenever locks show signs of resistance or after exposure to salt, moisture, or extreme cold.

How to Apply: Shake the bottle well before use. Insert the spray nozzle directly into the lock barrel and press to spray. Allow excess to drip away naturally.
