Countless cleaning hacks for every kind of household dirt may vie for our attention, but how do we know which ones really work and which ones will only leave you with a sticky mess that doesn’t actually do the job? Scientific evidence comes to the rescue, as chemistry professor Dario Bressanini teaches you everything worth knowing about cleaning agents and processes (and dispels plenty of myths, too). He answers all of our most pressing housekeeping questions: Is it more efficient to wash dishes in the sink or in the dishwasher? Does bleach remove dirt? Which cleaning supplies should I buy, and which can I make at home? Can vinegar and baking soda actually unclog your drain? How can I most effectively tackle different types of stains?
