Effective Home Remedies
For a cost-effective and chemical-free solution, you can create your own glass cleaner using common household items. 
Vinegar Solution: Mix one cup of white vinegar with one cup of water for a basic, effective cleaner. Add a tablespoon of cornstarch to the mixture to prevent streaks and achieve a polished finish.
Washing-up Liquid: For general dirt, a small amount of non-balsam washing-up liquid mixed with lukewarm water can produce great results.
Black Tea: Brew strong black tea and mix a large cup with approximately 3 litres of water. The tannins help cut through grease and even nicotine stains. 
Tip for best results: Clean windows on a cloudy day to prevent the solution from evaporating too quickly and causing streaks. Always use a microfiber cloth or squeegee for wiping to avoid lint and ensure a streak-free shine.
