Seeing black spots onto the bathroom floor can create disgust to anyone who will come in. Those black spots are most probably because of mold and mildew, which can’t be avoided in wet places such as bathrooms. You can avoid it by slicing a lemon in half, dipping the open side into some salt, and rubbing it over the black spots. And then leave it for about half an hour to allow the fruit’s acidity to do its job, then rinse away. You may have to do this several times to get rid of stubborn spots. However, if you don’t have lemons available, you can use white vinegar since it is also acidic and will work just as well. You may also use mold and mildew removers available in the market.
