Add orange peels (or any citrus peel) to a quart of white vinegar in a closed container and let it set for two weeks. Combine citrus/vinegar solution half/half with water and use for cleaning. Works on floors, tile, fixtures, etc. Smells good and is tough on scum! *** FYI from another Pinner Citrus is toxic to Cats & Dogs!! If you have best keep them away & out of area cleaning.
