Mother doesn’t necessarily know best. Most of us clean our houses with the products that we remember from childhood—if it was good enough for mom, it’s good enough for us. But the chemicals in cleaning products introduced since the 1950s have been linked to illnesses like asthma and allergies, among other nasties too numerous to mention. Try simple, chemical-free formulas based on tried-and-true cleaners like baking soda and vinegar. You can even make your own for pennies, and add essential oils for a more pleasantly scented experience. These are the cleaners your grandmother probably used. Maybe Mom should have listened to her!
