To clean your bathroom:
kazoka/ShutterStock The sight and smell of mildew is a bathroom’s enemy. Bring out the tough ammunition: a bottle of 3% hydrogen peroxide. Don’t water it down, just attack directly by pouring the peroxide on the offending area. Wipe it clean. Mildew will surrender.
To remove mold and mildew between your bathroom tiles, mix equal parts of chlorine bleach and water in a spray bottle, and spray it over the grout. Let it sit for 15 minutes, then scrub with a stiff brush and rinse off. You can also do this just to make your grout look whiter.
To clean outdoor stains:
Hannamariah/ShutterStock Bleach can get mildew and other stains off unpainted cement, patio stones, or stucco. Mix a solution of 1 cup chlorine bleach in 2 gallons of water. Scrub vigorously with a stiff or wire brush and rinse. If any stains remain, scrub again using 1/2 cup washing soda (this is sodium carbonate, not baking soda) dissolved in 2 gallons of warm water. While you’re cleaning, you may want to consider giving your patio a makeover.
To clean painted surfaces:
NinaMalyna/ShutterStock For painted surfaces and siding, bleach is your answer, again. Make a solution of 1/4 cup chlorine bleach in 2 cups of water and apply with a brush to mildewed areas. Let the solution set for 15 minutes, then rinse. Repeat as necessary. Check out these other smart uses for bleach around the house.
