The machine supplier is saying use alcohol and water. There has got to be limits on that though Id think. What ratio? etc. I thought we were only supposed to use materials with SDS's. Making our own solution sounds to...easy almost.
I would ask they exactly what are you suppose to use.
The problem with mixing alcohol on your own is not the SDS (you would have that for the alcohol). The bulk alcohol supplier would not have their product certified or approved by someone as a food contact cleaner / sanitizer. They would also not provide a label / mix instructions. it would also be difficult to verify concentration.
Alpet (and others) are not expensive because they use special IPA. Its expensive because they have taken time to get their product EPA, NSF approved for use in food plants (and elsewhere) and they have taken care of the dilution for you. (and alcohol is more expensive than quats, NaClO, etc)
