Operating Instructions
The Sea-Dog 491070-1 brush is designed for gentle yet effective cleaning of marine surfaces. Follow these guidelines for optimal results:
- Wet the Surface: Before cleaning, thoroughly wet the surface to be cleaned with fresh water. This helps to loosen dirt and prevents scratching.
- Apply Cleaning Solution (Optional): If using a marine-safe cleaning solution, apply it according to the solution's instructions.
- Gentle Scrubbing: Use light to moderate pressure when scrubbing. The soft bristles are effective without requiring excessive force.
- Utilize Side Bristles: For corners, crevices, and other hard-to-reach areas, angle the brush to engage the side bristles.
- Rinse Thoroughly: After scrubbing, rinse the cleaned area thoroughly with fresh water to remove all cleaning solution and loosened debris.
- Avoid Abrasive Surfaces: Do not use this brush on highly abrasive or rough surfaces that could damage the soft bristles.

Maintenance
Proper maintenance will extend the life of your Sea-Dog brush and ensure its continued effectiveness.
- Rinse After Each Use: After every cleaning session, thoroughly rinse the brush head with fresh water to remove all dirt, debris, and cleaning solution residue.
- Inspect for Damage: Periodically inspect the bristles for wear or damage. While durable, excessive force or contact with sharp objects can cause damage.
- Storage: Store the brush head in a clean, dry place, away from direct sunlight and extreme temperatures. Hanging the brush with bristles facing down can help maintain their shape.
- Avoid Harsh Chemicals: Do not use harsh solvents or chemicals to clean the brush itself, as this may degrade the plastic or bristles.
Troubleshooting
| Problem | Possible Cause | Solution |

| Brush not cleaning effectively. | Insufficient cleaning solution; bristles are worn; surface not pre-wet. | Ensure adequate cleaning solution is used. Inspect bristles for wear and replace if necessary. Always pre-wet the surface. |
