Lemon, the ingredient that solves many problems at home

Clean your oven: Lemon juice is a natural cleaner and can help remove dirt and grease from your oven. Cut a lemon in half and squeeze the juice onto the dirty areas. Leave on for 10 to 15 minutes, then scrub with a sponge or scrubber. Rinse with water and dry.
Freshen up your trash can: Place a few slices of lemon in your trash can and light it to help eliminate odors. You can also add a few drops of lemon essential oil for more freshness.

Remove Stains from Cutting Boards: If your cutting board has stains or odors, rubbing half a lemon on the surface can help remove them. Let the lemon juice sit for a few minutes before rinsing with water.
Polish metal surfaces: Lemon juice can also be used to polish metal surfaces like copper and brass. Cut a lemon in half and dip it in salt, then rub it over the surface. Rinse with water and polish with a cloth.
