Chlorine bleach -- the kind that's not safe for colored clothes -- is a cheap and strong way to kill germs. It can tackle the bacteria that make your toilet bowl pink and the virus that causes COVID-19. To make your own solution, mix 4 teaspoons of bleach with 1 quart of room temperature water. Open windows and doors, and keep your eyes and skin covered. Wipe the surface and leave it visibly wet for at least 1 minute. Make a new batch every 24 hours. Always use bleach exactly as directed.
