5. Why Cornstarch Outshines Commercial Cleaners
Cornstarch offers several advantages over commercial window cleaners. Firstly, it is non-toxic and free from harsh chemicals, making it safe for both the environment and your family. Many commercial cleaners contain ammonia or other strong chemicals that can irritate the skin and respiratory system.
Additionally, cornstarch is incredibly cost-effective. A single box can last for months, saving you money in the long run. Its natural properties ensure that it leaves no streaks or residues, providing a superior clean that many commercial products struggle to achieve.
6. The Environmental Benefits of Using Cornstarch
Using cornstarch as a cleaning agent is not only effective but also environmentally friendly. Cornstarch is biodegradable and derived from renewable resources, unlike many synthetic cleaning agents that contribute to pollution.
By choosing cornstarch, you reduce your reliance on plastic packaging and chemical-laden products, helping to minimize your carbon footprint. This small change in your cleaning routine can have a positive impact on the planet, making it a sustainable choice for eco-conscious households.
7. Common Mistakes to Avoid When Cleaning with Cornstarch
While cornstarch is a fantastic cleaning agent, there are some common mistakes to avoid for the best results. One mistake is using too much cornstarch, which can leave a residue on the glass. Stick to the recommended measurement of one tablespoon per quart of water.
Another mistake is not dissolving the cornstarch completely before use. Ensure you shake the solution well to avoid clumps that can cause streaks. Lastly, avoid cleaning windows in direct sunlight, as the solution can dry too quickly, leading to streaks.
8. How to Achieve Streak-Free Windows Every Time
To achieve streak-free windows, start by cleaning on a cloudy day or when the windows are in the shade. This prevents the solution from drying too quickly. Use a microfiber cloth or a squeegee to wipe the solution away, as these tools are designed to leave surfaces lint-free and spotless.
Work in sections, starting from the top and moving downwards. This ensures that any drips are caught and cleaned as you go. Finally, buff the windows with a dry microfiber cloth for an extra shine, ensuring no streaks are left behind.
9. Tips for Maintaining Clean Windows Longer
To keep your windows clean for longer, consider applying a water-repellent treatment after cleaning. These treatments cause water to bead and roll off the glass, reducing the buildup of dirt and grime.
Regularly dust window sills and frames to prevent dirt from transferring to the glass. Additionally, avoid touching the glass with your hands, as oils and fingerprints can quickly mar a clean surface. By incorporating these habits, you can enjoy clearer windows for extended periods.
