Quick and Easy Advice to Clean Windows
Window glass should always be clean therefore you have to wash it from time to time and rub it regularly with a soft cloth slightly moistened with sunflower oil, then wipe with dry cotton duster or blotting paper. It's recommended to clean and wash the window glass when the weather is cool and calm, since when the sun is too bright and there's a strong wind the glass dries very fast with iridescent stroke marks appearing on them.
It is thought that cleaners based on the chemical substances are the best for easy window cleaning but they can affect our skin and respiratory system because of toxic elements containing there, causing skin irritation, asthma and other serious diseases.
Today you can find a lot of natural detergents able to perform the same fast and perfect cleaning as the chemical ones. If you have time you can make it by yourself. If the glass is not very dirty, it can be cleaned with a solution of starch (1 tablespoon per 1 liter of cold water).
Too muddy glass can be washed with a solution of bleach (50 g per liter of water) or a warm solution of vinegar (2 tablespoons per 1 liter of water). Thus you'll save the health of your family and money.
Some people think that the window cleaning is not about the detergent but the tools they use. If you've decided to clean all the windows in your house from inside and outside, you have to remove all the screens at first and clean them with a sudsy water using a bristle brush to clear out some dead insects or spider webs.
Since the glass has a sensitive surface, it cannot be cleaned with sharp and bristle tools. If there are remains of plaster, paint, or dry dirt carefully cut them off with a blade, pressed to the glass at a small angle.
Window frames and sills are washed with liquid cleansers or warm water laced with ammonia (2 tablespoon per 1 liter of water). Don't add baking soda to the water when washing window sills and frames as it corrodes the oil-based paint, making it dull.
In winter it is recommended to apply a thin layer of glycerin on both sides of the glass to prevent it from freezing.
