3. Apply Cleaning Solution

• Mix cleaning solution in bucket (or use spray bottle)

• Scrub frames and sills thoroughly
• Use circular motions for best results
• Be careful not to scratch the glass

5. Squeegee Off Excess Liquid

• Overlap each pass slightly (about 1-2 inches)

• Use horizontal strokes for horizontal windows

6. Dry & Polish

• Never use sharp tools on the surface

Skylights & High Windows

• Always use proper safety equipment (harness, ladder)
• Consider hiring professionals for high-up windows
• Use extension poles for safer reach

Problems & Solutions

Streaks

• Use distilled water instead of tap water
• Ensure squeegee blade is clean
• Dry immediately with lint-free cloth
• Avoid cleaning in direct sunlight

Water Spots

• Use vinegar solution to remove mineral deposits
• Use distilled water for final rinse
• Polish dry immediately
• Consider water softener for regular cleaning

Stuck-On Residue

• Use plastic scraper (not metal) for stubborn spots
• Apply rubbing alcohol for dried paint or glue
• Repeat application if necessary

Professional Tips for Streak-Free Windows

• ✓ Timing: Clean on a cloudy day or when sun isn't directly on windows. Direct sun causes solution to dry too quickly, causing streaks.
• ✓ Newspaper vs Cloth: Crumpled newspaper is excellent for streak-free drying. Coffee filters also work well.
• ✓ Water Temperature: Warm water works better than cold for dissolving soap and dirt.
• ✓ Squeegee Technique: The key is keeping the blade clean. Wipe the blade after every pass.
• ✓ Order Matters: Clean outside first, then inside. This prevents dirty water from dripping on clean areas.
