A couple of drops of lemongrass essential oil every so often mixed with filtered or distilled water in my shark steamer, and not only do my floors and surfaces get clean but the house smells wonderful. I will occasionally mix in some vinegar to keep tank clean. (No URL).
It's cleaning day and the steam mop is at the ready. I love how simple it makes cleaning my floors and doesn't use any chemicals. Instead, I like sprinkle a few drops of essential oil on the cover to disinfect and make the house smell great. And it's safe for our dog, Murphy.
