Cleaning new or newly built windows after construction can sometimes be very tasking. Curtain dirt, paint stains, residues from adhesive, and other scrapes can make windows look dull and uninviting. However, with appropriate equipment, some strategies, and a little more time, you can effectively clean the windows.

1. Gather the Necessary Tools and Materials

As with any advanced preparation, check all the necessary tools and materials which will be needed. This will make it easier and more effective when undertaking the process.

• Basic Tools: Bucket, Sponge, Microfiber cloth, squeegee.
• Cleaning Solutions: Any mild dish soap, white vinegar or any commercial window cleaner.
• Specialized Tools: A razor blade scraper, an extension pole and a soft bristle brush.
• Safety Gear: Gloves for hand protection, safety glasses if the operator is making the change himself, and a good secure ladder if the tank is high.

2. Assess the Condition of the Windows

Look at the windows closely to decide how much cleaning will need to be done. Look for:

• Paint splatters or drips.
• Tough stains that are left behind from stickers or tape.
• Suspended particles, external contaminants and construction debris.
• It provides the information required to determine which cleaning method and equipment should be used.

3. Remove Loose Debris First

Begin cleaning the window by sweeping off the outer layer of dirt and dust off the window surfaces. It’s better to use a soft bristle brush or a dry microfiber clean cloth so that there will not be scratches on the glass.

• Tip: For the corners and edges, you should use a vacuum cleaner equipped with a brush.

4. Pre-Rinse the Windows

Use plain water to wash the windows to wash away the surface grime and dust. This step stops dirt and sand from rubbing the glass and causing damage to the surface during cleaning.

• Rinse the windows using a garden hose with moderate pressure.
• Do not use high-pressure washers since they may harm the glass or the windows’ seals.

5. Use a Mild Cleaning Solution

With warm water, add a few drops of dish soap or white vinegar to get a cleaning solution. Wipe the surface with a sponge or a microfiber cloth, from the solution above.

• Tip: To adopt eco-friendly cleaning methods, try a mixture of one part vinegar and one part water. Learn more about the best way to clean windows in New Zealand.

6. Address Stubborn Stains and Residues

For paint spills and any adhesive deposits, you may use a razor blade scraper or a window scraper.

• When using the scraper make sure to tilt it to around 45 degrees to prevent scratching the glass.
• When scraping wet the area to lessen friction.
• Try the scraper on a small hidden area before proceeding.

7. Rinse and Wipe Dry

As a final step clean the windows with clean water to wash away any remaining cleaning compound. The shower screen must be wiped clean with a squeegee.

• From that position bring the hand down in a single smooth arc starting at the top of the circle.
• It is recommended that in each stroke, you clean the blade with a cloth to avoid having streaks on the glass.

8. Clean Window Frames and Tracks

It is also important to wash the window frames and tracts because they get dirty when the construction is going on.

• Wipe gently with a soft brush if possible or with a vacuum cleaner.
• Washing with soap and water as well as washing the frames with a damp cloth.
• As for metal frames, it would be better to use a special cleaner which will not harm the metal and will not cause its rust.

9. Polish the Glass for a Streak-Free Finish

To avoid any buildup of spots and for that clean, shiny, streak-free look, clean with a microfiber cloth or window polishing cloth.

• To remove any last streaks of smudge, you should use circular movements.
• Do not clean the windows on the sunny side of the house; because when the solution dries, it leaves streaks on the windows.

10. Ensure Safety Precautions

Cleaning windows, particularly those outside may be risky because it is mostly done at heights. Follow these safety tips:

• An appropriate type of equipment is a ladder, and you should be sure that it stands steadily.
• Get someone to support and steady the ladder for him.
• Do not wear slippers or any type of slipper shoes and do not stretch beyond your limit.
• For windows in an area that is either difficult to reach or is always exposed to a lot of traffic, it might be wise to hire professionals.

11. Maintain Regular Cleaning

To maintain the shine of the window, it is most recommended that you set some window cleaning routine. This will reduce the chances of the region getting dirty and if ever it does it will be easier to clean.

• Wash the windows at least once in half a year or more often depending on where you live.
• In each cleaning session, one should check for signs of damage or signs of wear and tear.

What to Do If the Windows Are Still Streaky After Cleaning

Sometimes, even after following all the proper steps, your windows may still have streaks or smudges. This can be frustrating, but it’s usually easy to resolve with a few additional tricks. Here’s what you can do:

1. Reapply the Cleaning Solution

If streaks persist, it might be because there’s still some residue left on the surface. Reapply your cleaning solution (dish soap and water, vinegar and water, or a commercial cleaner) to the window, making sure to spray it evenly.

Then, use a soft microfiber cloth or squeegee to wipe it clean. Sometimes a second application is needed to lift stubborn marks.

2. Switch to a Clean, Lint-Free Cloth

If you’re using the same cloth repeatedly, it can transfer dust or dirt back onto the window. Make sure you’re using a clean, lint-free cloth, like a microfiber cloth. These fabrics are excellent for lifting dust, dirt, and grease without leaving streaks.

3. Use Distilled Water

Sometimes, tap water can leave mineral deposits on windows, leading to streaks. If you’re still noticing streaks, try using distilled water instead of regular tap water for your final rinse.

This eliminates the minerals that can cause streaks, ensuring a smooth, streak-free finish.

4. Buff with a Dry Microfiber Cloth

Once you’ve squeegeed the window, it’s helpful to buff the glass with a dry microfiber cloth. Buffing gently in a circular motion will pick up any leftover moisture or smudges that the squeegee couldn’t catch, leaving your window sparkling clean.

5. Use a Razor Blade for Stubborn Spots

For very persistent streaks or stuck-on residue (such as dried paint or adhesive), you may need to use a razor blade scraper.

Be sure to wet the surface first and scrape gently at a 45-degree angle to avoid scratching the glass. This should help remove any tough spots.

How Often Should You Clean Windows After Construction?

After a construction or renovation project, your windows are likely to have accumulated dust, debris, and even construction materials like paint splatters, adhesive, and grout.

To keep them looking their best, it’s important to clean them thoroughly after the work is completed.

However, the frequency of window cleaning after construction can vary based on a few key factors:

1. Immediately After Construction or Renovation

A thorough cleaning is necessary right after construction to remove any debris, dust, and stains that have accumulated.

This ensures that your windows are clear, and any potential damage caused by construction materials (like paint or adhesive) is addressed early.

You might need to clean the windows multiple times in the first few weeks to ensure you’ve removed all remnants.

2. Post-Renovation Cleaning Frequency

For general window upkeep, it’s recommended to clean your windows at least every 3 to 6 months after the construction is complete.

This timeframe helps ensure that any residual construction dust or grime that might have been missed in the initial cleaning is effectively removed.

3. Factors That Affect Cleaning Frequency

• Location: In New Zealand, homes near busy streets, coastal areas, or in urban environments will accumulate dust and dirt more quickly due to air pollution, pollen, or salt from the sea. In these cases, cleaning windows every 3 months may be a good option.

• Climate and Weather: New Zealand’s climate can have a major impact on window cleanliness. Coastal areas may experience salty air that can leave residue on windows, while areas with heavy rainfall can accumulate grime and algae. Cleaning frequency may need to increase if your windows are exposed to more environmental factors.

• Type of Renovation: If you’ve undergone a major renovation involving a lot of dust and construction activity, your windows may require more frequent cleaning immediately after. On the other hand, if the renovation was limited to a small area or non-invasive, window cleaning may only need to be done once.

4. Regular Maintenance
   After the initial cleaning, it’s advisable to maintain a regular cleaning schedule to keep your windows in good condition. Regular cleaning will prevent buildup of dirt, grime, and other pollutants, extending the life of your window surfaces and improving visibility. Aim for at least 2 to 4 cleanings a year, depending on your local environment.
