4. Clean hard water stains using a lemon.
This solution is simple and smart. Take a lemon and cut it in half. Use each half as a brush for each problematic spot. It is especially good for chrome surfaces. You can also add some salt for the more difficult spots.
Don’t forget to clean mirrors and glass surfaces. But if you forgot to buy a special spray, don’t worry. Domestic baking soda is a good method to make surfaces shiny.
If you don’t have baking soda, brew 3 bags of black tea and pour it into a spray bottle. After spraying on the mirrors, wipe it with a newspaper.
