How to prevent streaks or spotting on surfaces during cleaning.

Streaks or spotting can occur when dirt, debris, or uneven cleaning solution application leaves marks on surfaces. This guide will show you how to clean efficiently and achieve streak-free results.

Step 1: Pre-Rinse the Surface

• Lightly rinse the surface with water to remove loose dirt, dust, and debris.
• This prevents particles from causing streaks when the cleaning solution is applied.

Step 2: Choose the Right Cleaning Solution

• Select a soft wash chemical suitable for the surface (roof, siding, concrete, etc.).
• Mix the solution according to instructions and avoid over-concentrating, which can leave residue.

Step 3: Work in Small Sections

• Divide large surfaces into manageable sections.
• Apply the solution evenly across each section before moving on to the next.

Step 4: Avoid Overlapping Wet Areas

• Apply the cleaning solution consistently without letting it pool or dry unevenly.
• Overlapping wet areas can create streaks once rinsed.

Step 5: Use a Consistent Spray Pattern

• Keep the nozzle moving steadily at a consistent distance from the surface.
• Avoid lingering in one spot or spraying too close, which can leave marks.

Step 6: Rinse Immediately and Evenly

• Rinse each section right after applying the solution.
• Work from top to bottom on vertical surfaces to prevent dirty water from running over already cleaned areas.

Step 7: Inspect and Spot-Rinse if Needed

• After rinsing, check for any streaks or spots.
• Lightly re-rinse or gently scrub any areas that need extra attention.

Step 8: Allow Proper Drying

• Let the surface dry naturally.
• Avoid walking on it or applying additional chemicals until fully dry.

Step 9: Optional: Prevent Future Streaks

• Keep nozzles and wands clean to avoid uneven spray patterns.
• Avoid harsh sunlight during rinsing, which can highlight streaks.
• Inspect connections and fittings regularly for consistent performance.

Conclusion:
Following these steps will help you achieve a streak-free finish every time. Proper preparation, consistent technique, and careful rinsing prevent spotting and ensure professional results.

✅ Pro Tip: If streaks still appear, check your nozzle for clogs or wear—uneven spray is a common cause of streaking.
