DIY Window Cleaning for Streak-Free Results: Professional Secrets

Professional window cleaners charge $150-300 for whole-house cleaning, but you can achieve the same crystal-clear, streak-free results yourself. With the right techniques, tools, and homemade solutions, your windows will sparkle like never before. These professional secrets will transform your window cleaning routine and save you hundreds of dollars annually.

The Science Behind Streak-Free Windows

Understanding why streaks form helps prevent them:

• Soap residue: Too much detergent leaves film
• Hard water minerals: Create spots when water evaporates
• Wrong tools: Paper towels leave lint and streaks
• Hot surfaces: Solution dries too quickly
• Dirty tools: Spread grime instead of removing it
