Mixing Green Soap

Green Soap can be mixed and diluted to different concentrations for different applications. A mixture of ten percent green soap and ninety percent distilled water will be effective for preparations. A mixture of one cup of green soap to 1 quart of distilled water will make a very effective all-purpose cleaner that can be used in spray bottle to clean work areas or as a soaking agent for needles, tubes and tips.   Green soap is not a substitute for properly sterilized equipment that should be sterilized in an autoclave. If an autoclave is not available for needles, tubes, and grips, just go disposable.

Green Soap for Stencil Transfer

You can use Green Soap for stencil transfer. After shaving the area to be worked with, wipe the area clean with a clean paper towel that is soaked in green soap to remove loose hair. Moisten the area with green soap sprayed from a spray bottle. Apply and spray the purple stencil (one for transfer) with green soap and wipe over it with a paper towel before removing the transfer.
