I have access to an autoclave at my friends tattoo shop.
Originally I tried to use tap water and then baking the vials to kill off the heat. The problem was that the tap water left white residue from elements in the water behind on the inside of the glass. If I was to give these vials to friends in the gym they wouldn't really trust it .
Second attempt, I tried to wash it with distilled water. I filled a beaker with distilled water and dipped the vial into it, washed it out a few times without using an instument to wipe/clean inside the vial. I then placed them into an IPA bath which appeared to make the vial totally clean, glossy and smooth. However, Once it dried you could still see the marks on the inside.
I went ahead and autoclaved a bunch of vials that went through a 134 degree cycle with vacuum and drying, the vials came out with the white residue on the inside and if you hold it up to light you could sell all of it.
Does anyone know the best way to make really clean vials visually and medically?
