Here’s a guide to expert post-construction window cleaning, ideal for professionals or anyone tackling tough construction residue:

1. Assess the Windows First

• Check for any scratches or damage. This will help you avoid causing further damage during cleaning.
• Identify types of debris like paint splatter, cement dust, or adhesive residue, as different methods will address each effectively.

2. Gather the Right Tools

• Soft bristle brush for dust and loose debris.
• Razor scraper with a fresh blade to gently remove hardened paint or stickers.
• Microfiber cloths for polishing and final touches.
• Window cleaning solution or a DIY mix (equal parts distilled vinegar and water).
• Non-abrasive scrubbing pads for stubborn spots.
• Extension poles or scaffolding for hard-to-reach windows.

3. Start with Dusting and Brushing

• Use a soft bristle brush to remove loose dust and debris from the window surface, frame, and surrounding areas.

4. Use a Razor Scraper Carefully

• Wet the window with cleaning solution before scraping.
• Gently use the razor at a 45-degree angle to lift paint or adhesive. Avoid scraping dry surfaces, as this can cause scratches.

5. Apply Cleaning Solution Generously

• Spray the cleaning solution over the window, let it sit for a few seconds, and wipe with a microfiber cloth.
• For stubborn stains, use a non-abrasive pad. Circular motions often work best.

6. Polish the Window

• Finish by polishing with a dry microfiber cloth for a streak-free finish. Wipe horizontally inside and vertically outside, so streaks are easy to identify.

7. Final Inspection

• Check from different angles to ensure all debris and streaks are removed. Pay attention to corners and edges where dust can accumulate.

Tips:

• Change blades often and use them only for one job to avoid scratching.
• Avoid harsh chemicals that can damage the glass or frames.
• For tinted or coated glass, consult the manufacturer’s guidelines before using a razor or harsh cleaner.

This approach ensures post-construction windows are clean, scratch-free, and polished to a high standard.
