If you add vinegar and essential oils together, it actually smells completely different. Try a capful of the essential oil in a spray bottle of white vinegar.
Baking soda is great for scouring, but if you need any anti-bacterial needs, the baking soda will fall short (this is probably first time in this forum I've ever said anything slightly negative about baking soda....SORRY BAKING SODA, I LOVE YOU!!!)
You can add tea tree oil for antibacterial purposes (lavender has some antibacterial properties, but tea tree oil kills nasty stuff like staph and e.coli).
I've also heard you can make a buffered solution with vinegar and baking soda (which doesn't smell like anything much), and that works great too.
