Clear glass lets you enjoy your view and get the full benefit of your windows, whether they’re picture windows, double hung, or bay and bow styles.

This blog shares simple interior window cleaning tips you can do at home. No need for fancy tools or chemicals; just a few basics and the right approach. These tips help your windows stay streak-free between deep cleans or replacements.

6 Interior Window Cleaning Tips

These easy tips can help you clean your window glass, frames, and screens with simple tools and a few everyday ingredients:

1. Start With a Dry Dusting First
2. Make or Choose the Right Glass Cleaning Solution
3. Use the Right Cloth for a Streak-Free Finish
4. Clean Window Screens Separately
5. Don’t Forget About Interior Exterior Window Cleaning
6. When to Clean and How Often

1. Start With a Dry Dusting First

Dust and debris stick to windows and frames, so it’s best to dry dust before adding any cleaner. This helps avoid smearing and makes your work easier.

• Always start at the top and work your way down
• Use a microfiber cloth or lint-free towel
• Wipe down window frames, sills, and corners
• Don’t forget to dust the glass itself

2. Make or Choose the Right Glass Cleaning Solution

You don’t need to buy expensive cleaners. A quick homemade mix works just as well for most indoor window cleaning jobs.

• Mix equal parts white vinegar and water for a simple solution
• For extra grease-cutting power, add a drop of dish soap
• You can also use a store-bought glass cleaning solution
• Stay away from anything too harsh that might damage the finish or coating

3. Use the Right Cloth for a Streak-Free Finish

Old towels and paper towels can leave lint behind. The right cloth gives a clean finish with fewer streaks.

• Use a clean cloth, lint-free towel, or microfiber cloth
• Wipe in an “S” motion instead of circles
• Buff dry with a second cloth for extra shine

4. Clean Window Screens Separately

Dirty screens block light and transfer grime to your glass. Cleaning them takes just a few minutes.

• Take screens off and rinse them outdoors
• Use soapy water and a soft cloth or sponge
• Let them dry completely before reinstalling

5. Don’t Forget About Interior Exterior Window Cleaning

Some windows are made to be cleaned inside and out, especially double-hung, casement, or horizontal sliding windows. If yours tilt in, take advantage.

• Clean both the interior and exterior window surfaces when the design allows
• Wipe down the window sashes, tracks, and hardware
• Use a soft brush to knock off dust and dirt from the outer frame
• Clean on a cloudy day to prevent streaks from fast-drying cleaner
• For upper-story windows that don’t tilt in, consider using a long-handled tool or hiring a pro

6. When to Clean and How Often

Not all windows get dirty at the same pace. Some need cleaning more often than others, especially near kitchens or bathrooms.

• Clean your windows at least once per season
• In busy areas, plan for a monthly wipe-down
• Wipe up smudges and fingerprints as needed between full cleanings
• Use cleaning time to check for foggy glass, seal failure, or frame damage
