5. Making your own glass cleaner
Why would you want to buy glass cleaners when you can make your own product that is cheap and non-toxic? Just pour 2 liters of lukewarm water into a deep bowl. Then add 50 ml white vinegar and half teaspoon of dishwashing liquid. Stir well and then fill up a plastic spray bottle with the mixture. Use it to clean windows and mirrors. Make your glass surfaces clean and shiny.
