How to clean plastic containers for filtered water

Due to the kind of water recommended for usage for a "supergreen" powder supplement mixtureI bought (from a radio infommercial!!), I have a question about how to clean the plastic gallon container used for the liquid.

The company that makes the green powder supplement advises to use filtered water for the mixture with the powder due to the chlorination effect from tap and/or unfiltered water. A local supermarket has a large water filter machine (reverse osmosis, ultraviolet light, carbon activated filter, repeated filtering process, all for 40 cents per gallon!!) which dispenses the filtered water into empty gallon plastic containers which are available at the store. I read on the label of the container the message "clean between uses."

Well, for those of us that don't have a filter attachment at the kitchen sink, that would mean using tap water and who knows what other cleaner for the inside of the container which has a very narrow opening. The water and cleaner I'm sure would leave a residue on the inside of the container. There is a white powdery coating left on the inside of containers (from hard? soft? water) here.

I need to dispense the filtered water into the green powder supplement.
Any suggestions for how to clean this container given the kind of tap water I have to use? I hesitate to use a white vinegar mixture, due to my concern of not being able to completely remove any remnant of the vinegar from the interior of the container.

And ... I don't know why the container has to be cleaned, in the first place between uses.
I just use it for the filtered water that is dispensed from the machine, and then store the water in my refrigerator. The only time I'd be exposing the container to "room temperature" for an extended period of time is during the return trip to the market to fill the container up again.

I don't want to buy distilled water at the store. I like the idea of being able to reuse the plastic container the water is dispensed into. I don't think there is much "leaching" of the petrochemical residue into the water as there might be from other containers that have held water for long periods of time and which have been subjected to exposure to sunlight. And at 40 cents a gallon for this triple filtration process, the price is right. The water tastes clean, too.

(By the way ... the taste of the green supplement powder is very good!! Hard to believe it's still healthy, too. No refined sugar, just stevia and spearment for the sweeteners.)

  1. If you are concerned about "leaching of the petrochemical residue" you could always use glass.

    To clean you might want a low residue detergent:

    As for sterilization nothing beats an autoclave:

    Polycarbonate is also available :

    1. Home brewers have exactly the same problem. It's been way too long since I've
      made any beer at home for me to remember the rituals, but you might try searching
      for "carboy" and "cleaning". For example, this is the first thing that pops up:

        After years of providing the water filter machine in the supermarket, this market decided to remove it. Just after I had gotten one gallon and decided to start using it more often. It had been available for years, was very inexpensive to use, provided decent filtering, and offered the consumer an ecological way of getting filtered water without having to use new plastic containers everytime he/she went to the store and bought spring or distilled water.

        For this green powder supplement I started taking, I'd rather err on the side of safety and buy distilled water vs. spring water, and/or use my PUR water pitcher filter (and the idea of consuming a new filter every two/three months, doesn't thrill me as far as not adding to the waste in the environment, either).

        I don't use alot of water, and it may be more efficient to just buy the distilled water as needed for the supplement, whose credibility I still wonder about. In the supplement industry, you don't necessarily get what's advertised. I really don't know if the advertised content of the product is what is really contained in it to the exact degree as listed.
