As the vibrant hues of spring start to paint the world outside, it’s the perfect time to rejuvenate your home, starting with your sash windows. Parsons Joinery understands the importance of maintaining the timeless elegance of these classic features. In this guide, we’ll walk you through the steps to ensure your sash windows sparkle from the inside out, ready to welcome the sunshine and fresh breeze of the season.


Step 1: Gather Your Supplies

Before diving into the cleaning process, gather all the necessary supplies. You’ll need:

  • Mild detergent or window cleaner
  • Microfiber cloths or sponges
  • Soft-bristled brush or vacuum cleaner with a brush attachment
  • Bucket of warm water
  • Old newspaper or absorbent cloths

Ensure that your chosen cleaning products are suitable for use on glass and won’t damage the delicate framework of your sash windows.


Step 2: Prepare the Area

Start by preparing the area around your sash windows. Remove obstacles such as curtains, blinds, or decorative items to ensure unobstructed access. Lay down old newspapers or clothes to catch any drips and prevent mess on your floors or windowsills.


Step 3: Dust and Vacuum

Begin by dusting the window frames and sills using a soft-bristled brush or a vacuum cleaner with a brush attachment. Pay attention to corners and crevices where dust and debris tend to accumulate. This initial step will help prevent dirt from spreading when you apply water later.


Step 4: Wash the Glass

Next, prepare a mild detergent or window cleaner diluted in warm water. Dip a microfiber cloth or sponge into the solution and gently scrub the glass panes, starting from the top and working your way down. Avoid using abrasive materials or harsh chemicals that could scratch or damage the glass surface.


Step 5: Rinse and Dry

Once thoroughly cleaned, rinse the glass with clean water to remove any soapy residue. Wipe the glass dry using a clean microfiber cloth to prevent streaks and watermarks. You may need to repeat the cleaning process or use a specialised glass cleaner for stubborn stains or spots.


Step 6: Clean the Frames and Sills

Remember to clean the window frames and sills to complete the rejuvenation process. Dip a cloth or sponge into the soapy water solution and gently scrub the frames and sills, especially areas with built-up grime or mould. Rinse with clean water and wipe dry with a separate cloth.


Step 7: Polish and Shine

For extra brilliance, polish the glass and frames using a clean, dry microfiber cloth or newspaper. Buff the surfaces in circular motions to remove any remaining streaks and enhance the shine of your sash windows.


Step 8: Final Touches

Once you’ve finished cleaning your sash windows, inspect them for any signs of damage or wear. Repair loose or damaged components, such as cords, pulleys, or weather-stripping, to ensure smooth operation and optimal energy efficiency.



With these simple steps, you can ensure that your sash windows are sparkling clean and ready to embrace the beauty of spring. Regular maintenance and cleaning not only enhance the appearance of your windows but also prolong their lifespan, preserving their timeless charm for years to come.
