Bathroom Odors: Place an opened box of baking soda OR an open container of activated charcoal behind the toilet to absorb bathroom odors.
Blood Stains: Soak the stain in hydrogen peroxide, wash (don't dry), and repeat if necessary. This tip works especially well for caret and clothes.
Carpet Stains: Baby wipes are miracle-workers on carpet stains, from motor oil to blood, they remove almost anything!
Deodorize dishes, pans, cutting boards or utensils with pungent odors by adding 1/4 cup of lemon juice to your dishwater.
Dishwashers: To clean mineral deposits from the inside of your dishwasher, pour in a container of Tang® Drink Mix and run the dishwasher (don't put dishes in the dishwasher for this load).
Fish or Spoiled Food Odor: Place a bowl of white vinegar on the counter for a few hours. The odor will disappear for good.
Freshen a Garbage Disposal: Sprinkle baking soda in it along with a few drops dish-washing liquid. Scrub with a brush (a new toilet brush works great), getting under the rubber gasket and all around the inside. Then, turn on water and let the disposal run to flush thoroughly. For a fresh citrus scent, throw in a few cut up lemons or limes and run them through, too, using lots of water.
George Foreman Grills: After removing the cooked food from the grill, place a paper towel soaked in water on each of the 2 cooking surfaces. Unplug the appliance, allow it to sit for 5-30 minutes (while you eat), then use the paper towels to effortlessly wipe out the grease and food particles.
Ink Stains: The best way I have found to get out ink stains is to put rubbing alcohol on the stain - it disappears! This must be done before washing. For ink on the wall, wipe with bleach and it will disappear.
Kitty Litter: To keep cat litter fresh smelling, mix baby powder in with the litter.
Microwave Filth: Food splatters all over the inside of your microwave and cooks itself on after time. To easily remove this mess, place a sponge soaked in water in the microwave. Cook on high heat for 2 minutes, then allow it to sit without opening the microwave door, for 5 minutes. The filth is now ready to be wiped right off - no scrubbing - and your sponge is right there!
Microwave Odors: Keep a cup of baking soda in the microwave between uses to keep potatoes from smelling like bacon or other unusual combinations!
