I use the same cleaner for the bathroom and kitchen, but I enjoy different scents for each one.

Save a jar to put lemon peels in. Any time you use a lemon, put the peel in the jar (think peanut butter or pasta sauce jars). Store the jar in the freezer. Once the jar is 1/2 to 3/4 full with lemon peels, add in white vinegar to cover the lemon peels. Store the mixture in a cabinet for 7 days or until the vinegar turns a dark shade of yellow.
Remove the lemon peels from the vinegar and compost them.
Pour equal amounts lemony vinegar and distilled or boiled and cooled water into your spray bottle.
Add 20 drops of essential oils. I enjoy orange & tea tree for the kitchen (10 drops each), and lavender & peppermint for the bathroom.
If you have any of the lemony vinegar left over, it makes a wonderful concentrated cleaner.
