Why Summer Window Cleaning Is Especially Challenging

The Science Behind Streaks in the Sun

Summer sun speeds up evaporation. Fast drying of water and cleaning solutions produces residue on surfaces. The remaining substance that produces bothersome streaks appears after cleaning solutions evaporate too fast. The speed of this process increases directly with rising temperature levels.

Common Mistakes People Make in Hot Weather

• Cleaning during midday when sunlight is strongest
• Using too much cleaning solution
• Not rinsing or drying properly
• Ignoring dusty window frames

The Best Time to Clean Your Windows in the Summer

Morning or Evening – What’s Better?

Summer window cleaning should take place during early morning hours or from 6 PM onwards. During these times when temperatures remain cool and sunlight shines indirectly the cleaning solutions can operate effectively before they dry too quickly.

Why You Should Avoid Direct Sunlight

Sunlight creates rapid drying while showing all window flaws to the naked eye. The absence of direct sunlight exposes all window defects because streaks and smudges become more noticeable.

A cloudy day serves as your top tool for achieving streak-free window cleaning.

Tools and Supplies That Make a Difference

Essential Supplies for Streak-Free Cleaning

Here’s what you’ll need:

• • Microfiber cloths (no lint, reusable)
  • Rubber squeegee (10″-14″ works best)
  • Bucket with warm water
  • Spray bottle with homemade or eco cleaner
  • Paper towels or lint-free towels
  • Optional: window vacuum

Homemade vs. Store-Bought Products

A popular homemade recipe includes:

• 1 cup white vinegar
• 1 cup distilled water
• 1 tbsp rubbing alcohol

The mixture works well while preserving environmental safety and proving suitable for interior applications. Windex and Sprayway remain effective commercial cleaners for windows but choose high heat versions that are free from ammonia.

Step-by-Step Guide to Streak-Free Windows

Step 1: Prep Your Area

Place towels under the windows to collect any dripping solution. Cobwebs and dust require removal through the use of a handheld vacuum or brush. A dirty frame will result in window smudges so you must clean it.

Step 2: Wash With Purpose

Apply your prepared solution by spraying it directly onto the glass surface or by spraying it onto a microfiber cloth. Use circular motions to remove dirt from the window surface. Apply the squeegee in a straight pass through an “S” pattern starting from the top to the bottom.

Step 3: Dry Carefully

A clean microfiber towel or paper towel should be used to dry the edges of the glass. Make sure to blot, not rub.

Still seeing streaks? You should either change your cleaning tools or use less solution during the process.

What to Avoid When Cleaning Windows in the Summer

Avoid these streak-causing habits:

• Midday Cleaning: Fast evaporation = streaks.
• Old Cloths: Towels with lint or oils leave marks.
• Excess Cleaner: More doesn’t mean better.
• Skipping the Rinse: Always finish with a clean-water pass or drying step.

Hot windows should never be cleaned because it creates an effect similar to dirty steam during ironing.

Bonus Tips from Professional Cleaners

• • Clean from the top down to avoid drips.
  • Use a second person to speed up drying.
  • Keep two cloths handy: one damp, one dry.
  • Don’t forget the screens! Remove and rinse with a hose.
  • Spray solution on the cloth, not the glass, for inside windows to avoid over-spray.
