This is what I use, and it beats the heck out of Vape Wizard
In the First Aid section of the pharmacy, pick up some .9% Saline (Wound Wash/Flush).
It's used to clean out open wounds .. safe for a baby.
It's pure sterile water with .9% saline solution, and comes in a spray can.
It comes out of the can in a stream that is easy to direct into a dripper bottle.
I add about 1 drop per 2ml. to my juice.
It brings out the flavor (just like salt does in cooking), ... it smooth's out the harshness (maybe the bitterness you pick up on), .. and blends the flavors together.
It works especially good with fruits and chocolates.
You will not taste any salt, as it's super mild.
It will "brighten" the flavor of the fruit, but I find it doesn't help banana
It changes the PH in the juice, and cuts the acid.
There is also a saline solution you spray/inhale up your nose ..but that's the wrong one.
It has added ingredients.
You want the one without anything in it except the .09 saline and sterile water, that is used to clean wounds.
Have fun experimenting.
