ozonated water for rinse cycle in cleaning vinyl

No problem, ozonated water is part of process to kill bacteria. I think UV light does the conversion.

Should you wish to go with even more pure water, lab grade is sold via internet and I've had the best results with NERL Reagent grade.

Both responses are slightly off.

The water has been treated by passing O3 through it from an ozone generator (basically an electrical arc in air). The half life of ozone in water is quite short so no dissolved ozone will remain.

The purpose of the treatment is to kill any bugs in the water before it is packaged.

One problem with ozonation is that if there is any appreciable bromine in the water it will react with the ozone to form bromate which is a health hazard. If the water was adequately deionised in the first place this is not a concern.

Several of my neighbors are scientists and research Dr's and all of their labs have the equipment to purify water to "laboratory" grade. They have explained the process at length, although I don't remember the particulars, and it is a much different product than anything you can buy in a store.

I rotate who I ask, but they all are great about getting me a few quarts at a time to clean my vinyl. The hardest part is getting a container sterile enough to put it in. I give the the bottle, and they sterilize it again prior to putting the water into it.

Remember also that water is the universal solvent. Perfectly pure water is corrosive, it has an affinity for dissolved ions, and will etch at any container you put it in.
