Cleaning laminate countertops: Cut and squeeze the juice onto the counter. Using the lemon as a scrubber, work the juice over the stains. Leave the juice on until the stains disappear then rinse with water and dry.
Cleaning brass: Use the same method for cleaning solid brass as for copper – one half of a lemon with salt sprinkled on it and rub until it is clean. Rinse well with water.
Removing rust from clothes: Put lemon juice on the rust stain and then sprinkle cream of tartar onto the top of the juice. Rub in the solution and let it sit on the stain until the rust is gone.
Bleaching white clothes with lemon juice: Mix 1/2 cup lemon juice with one gallon of very hot water. Soak the clothes (only cotton and polyester) in the solution. Let the clothes soak from an hour to overnight, depending on how badly the clothing needs bleaching.
Remove the clothing from the mix and pour the mix into the washing machine and wash as usual. It's impossible to over-bleach using lemon juice.
Getting stains out of Tupperware: Squeeze lemon juice in the container and then add baking soda. Use the lemon as a cleaning tool and work it in. If the stains are bad, let it sit overnight before scrubbing the stains.
