Cleaning Tips And Tricks

Ammonia-based cleaners -  Ammonia can damage window tints, seals, and rubber gaskets. It can also release toxic fumes, causing respiratory issues.
Abrasive cleaners - Scouring powders and abrasive sponges can scratch the glass surface, leaving permanent marks.
Vinegar  - on certain windows should not be used on leaded or stained glass windows, as it can damage the glass and deteriorate the leading.
Newspaper - as newspaper ink can leave residues and smear on the glass surface.
Dishwashing soap - Some dishwashing soaps can leave a film on the glass, resulting in streaks and a cloudy appearance.
Chemical-heavy cleaners - Cleaners with harsh chemicals can damage window films and other protective coatings, as well as pose health risks when inhaled.
Bleach or other strong acids -  These can cause irreversible damage to the glass and surrounding materials, as well as pose health and safety risks.

Fill a bucket with warm water and add a few drops of mild dishwashing soap, or use a commercial glass cleaner.

Use a soft brush or cloth to brush away any loose dirt or debris from the window frame and glass surface.

Gently scrub the window frame, paying close attention to corners and crevices. If you're dealing with a wooden window frame, avoid using excessive water to prevent damage to the wood.

Use a damp cloth or sponge to wipe away any remaining dirt and cleaning solution from the window frame. Dry the frame with a clean, dry cloth or towel.

Dip the sponge or soft cloth into the cleaning solution and apply it to the glass surface. Use circular motions to clean the entire window.

Use a squeegee to remove excess water and cleaning solution from the glass. Start at the top of the window and work your way down, making horizontal or vertical strokes. Wipe the squeegee blade with a clean, dry cloth after each stroke.

Use a microfiber cloth or lint-free towel to dry the edges and any remaining streaks on the glass surface.

Firstly, protect yourself _ Wear protective gear such as gloves, a mask, and goggles to prevent contact with mould spores and protect your eyes and lungs.
Then ventilate the area - Open the windows and doors to increase air circulation while you clean.
Remove visible mould, Use a soft brush or cloth to gently remove visible mold from the window frame and glass surface. Be cautious not to spread mould spores to other areas.
Clean the affected areas: Mix a cleaning solution of water and mild dish soap, or water and white vinegar (1 part vinegar to 3 parts water). .
Disinfect the area: After cleaning with soap or vinegar, you can use a solution of water and bleach (1 part bleach to 10 parts water) to disinfect the window frame. Apply the solution with a cloth or sponge and let it sit for a few minutes, then wipe it off with a damp cloth. 

(Avoid using bleach on wooden window frames, as it can damage the wood. Instead, use a fungicide or a mould-killing product designed for wood)
Dry the area: Use a clean, dry cloth or paper towel to wipe the window frame and glass dry. Ensure that all surfaces are completely dry to prevent mould regrowth.
Address the root cause: Identify and fix the cause of dampness and mould, which could be poor ventilation, condensation, or water leaks. Install a dehumidifier or use a moisture-absorbing product to reduce humidity, and ensure proper ventilation in the room.
