Very economical - smells like bleach
I've made a few batches and bought a spray bottle just for this.  It does have a faint smell of bleach.  It's not as strong as regular bleach and don't feel like the scent lingers after I've wiped down my kitchen counters.  I like using this in my kitchen sink to get rid of any germs.  I spray my kitchen sponge, kitchen brush, etc.  Since it costs nothing to make, I've poured some in my toilet tanks to disinfect the bowls.
