Directions for Use
Shake gently before use.
Ensure the leather surface is free of loose dust or dirt.
Application:
Drying - Allow to dry naturally at room temperature.
Crucial Note:
Avoid heat guns or drying temperatures above 50°C (122°F) to ensure the active bactericide does not degrade.
Once dry, brush suede gently to restore its original plush texture.
For Smooth Leather:
Apply evenly using a soft lint-free cloth, a wool dauber, or a light mist spray.
Wipe away any excess run-off.
For Suede & Nubuck:
Spray a very fine mist from a distance of 20–30 cm (8–12 inches).
Do not saturate or soak it.
Recommended Application Frequency
To keep your favorite leather goods continuously protected against destructive bacteria, mold, and daily odors, use LeatherGuard 3.7 according to your lifestyle:
- Everyday Essentials (Shoes, Jackets, Bags, Wallets):
- Apply every 3 to 4 months.
- Regular contact with skin oils, sweat, and outdoor elements wears down standard protection.
- A quick seasonal mist keeps your items fresh and safe.
- High-Moisture & Rainy Seasons:
- Apply every 2 months.
- If you live in a humid climate or frequently wear your leather boots and coats in the rain, apply more often to stop mold spores from taking root.
- Car Interiors & Leather Furniture:
- Apply twice a year (every 6 months).
- This provides a long-lasting, invisible shield against deep-set spills, pet odors, and trapped moisture in enclosed spaces.
- Seasonal Storage (Winter Coats, Boots, Travel Bags):
- Apply once right before storing.
- Spray your items lightly and let them dry completely before packing them away to guarantee they stay mold-free and smell fresh for the next season.
