Removing Caulk
To remove old or discolored caulk, use the sharp edge of the scraper. Apply firm, even pressure along the caulk line to cut and lift it from the surface. For stubborn areas, the pointed tip can help dislodge material from tight corners.

Scraping Surfaces
For general scraping of paint or other materials, hold the tool at a shallow angle to the surface and push forward. The stiff blade provides excellent leverage. The thumb depression on the handle (for models with this feature) enhances grip and control during scraping.

Maintenance
To ensure the longevity and optimal performance of your Warner ProGrip 5-IN-1 Glazier Knife, follow these maintenance tips:
- Cleaning: After each use, clean the blade thoroughly to remove any paint, putty, or other materials. Use a damp cloth or appropriate solvent if necessary.
- Drying: Dry the blade completely after cleaning to prevent rust.
- Storage: Store the tool in a dry place, away from moisture, to maintain its condition.
Troubleshooting
If you encounter issues with your tool, consider the following:
- Dull Blade: While designed for durability, prolonged heavy use may dull the blade. Sharpening is generally not recommended for this type of tool; replacement may be necessary for optimal performance.
- Material Buildup: If material is difficult to remove, ensure the blade is clean and free of hardened residue. Soaking in an appropriate solvent (e.g., paint thinner for oil-based paint) may help.
