You can spray this mixture onto different surfaces, and then wipe the surface down with a clean cloth.  This cleaner can be used as an all-purpose, non-toxic cleaner in kitchens and bathrooms. Always shake well before using because the oil naturally separates from the vinegar and water. Add tea tree oil to a smelly trash can.
