My wife loves the smell of lemons so she incorporates them whenever possible to make our house smell lemony. An added benefit is that using lemons instead of store bought house cleaners and fresheners is a lot less expensive and better for the environment. Here are some of many ways she uses lemons around our house as a cleaner:

Soap Scum: If you apply lemon juice directly to soap scum and hard water deposits, the lemon juice will help dissolve them. You may have to let the lemon juice sit on the area for a few minutes.

Brass & Copper: If you use a dab of lemon juice on a rag, you can clean and shine brass and copper.

Cleaning Paste: If you need some cleaning paste, mix lemon juice with vinegar and then add some baking soda. This makes a good cleaning paste

Stain Remover: Take a lemon and cut it in half. Sprinkle a small amount of baking soda across the cut section. The half lemon can then be used to scrub dishes, clean surfaces and help remove stains.

Pots & Pans Take a lemon and cut it in half. Sprinkle small amount of salt across the cut section. The lemon half can then be used to clean and shine the copper bottoms of pots and pans.

Hardwood Cleaner: You can mix lemon juice with olive oil to make a polish for hardwood furniture in your house.

We also use lemons to freshen:

Garbage Disposal: If you use the lemon juice and have the lemon slices left over, don’t throw the peals away. You can place the peels through the garbage disposal. No only will they freshen the drain, they will also clean the garbage disposal blades (you can also do this with orange peals).

Vacuum: Before vacuuming, squeeze a few drops of lemon into your vacuum cleaner bag. The air flow will give your entire house a clean, lemon scent.

Lemon Cleaner Aroma: If you use vinegar as your main cleaner (four cups water and one cup white-wine vinegar), one problem is the vinegar small that it can leave. Simply take a few lemon peels and add them directly to the vinegar solution. Be sure to twist them a few times to get the a strong lemon smell. The peels will will help neutralize the harsh vinegar smell.
