22. Tea Kettle
Simply mix 1 cup of lemon juice to 2 cups of water, and pour that into your kettle. Bring it to a boil and then let it cool. Empty the kettle, give it a good rinse, and voila: your kettle will be shiny and clean once again.
23. Soap Scum
To remove soap scum, cut a lemon in half and rub it on all scummy surfaces – or simply mix some lemon juice in a spray bottle and spritz it around. Let the lemon juice sit for a minute and then wipe clean using a damp cloth.
