I'm super sensitive to smells. The littlest things can be migraine-inducing for me. Because of that, I prefer unscented cleaning supplies, but sometimes it's nice to have a fresh scent accompany a cleaning job.
Here's my little secret:
I love essential oils because they're pure scents, rather than chemical ones, and I can choose the ones I like and can tolerate. I use them in the cleaners that I make myself. My personal favorites for cleaning are lime, peppermint, and lavender.
When I mop, I use 1 tablespoon of borax in a gallon of hot water. Easy and unscented. Add a few drops of essential oil to the mop water, and mopping because a more pleasant task.
The scent even lingers for a while afterwards, making the house smell clean, in addition to looking clean.
