**Washing Soda**, also known as **sodium carbonate** (Na₂CO₃), is a versatile, alkaline compound often used in cleaning products. It is a white, odorless powder or crystalline substance that is highly effective in removing grease, oil, and stains. Washing soda works by breaking down dirt and grime, softening water, and enhancing the effectiveness of detergents. It can be used in various household cleaning tasks such as laundry, cleaning bathrooms, kitchens, and even unclogging drains. Washing soda is also a natural mineral that can be safely used in eco-friendly cleaning formulations. However, it is important to handle it with care, as it is more caustic than baking soda and can cause irritation if it comes into contact with skin or eyes.

**Glass Cleaner** is a specially formulated liquid designed to clean and shine glass surfaces, leaving them clear and streak-free. It effectively removes dirt, dust, fingerprints, smudges, water spots, and grease without leaving behind any residue. Glass cleaners often contain a mix of surfactants, solvents, and sometimes ammonia or alcohol, which help to dissolve grime and evaporate quickly for a streak-free finish. This product can be used on a variety of glass surfaces such as windows, mirrors, tabletops, and even automotive windshields. Many glass cleaners are also safe for use on other shiny surfaces like chrome and stainless steel, providing a versatile cleaning option. Some glass cleaners are available in eco-friendly or ammonia-free formulations, making them safer for indoor use or sensitive environments.
