    Question Taylor K 1766: question re black stains in test vial

    The little vial I test my salt with has black stains that I would love to get rid of. I can barely make out the 10ml which I need to be able to see. Picture: http://i77.photobucket.com/albums/j4...pse0157b5d.jpg

    Normal soap like ivory doesn't cut it, and I put it in the dishwasher (top shelf) and even the dishwasher didn't put a dent in the black stains.

    Suggestions on how to remove? Maybe muriatic acid on a q-tip would work?

    Thank you in advance.

    Try some diluted muriatic acid. Odd that the salt test is making it black, I only get some white buildup where the SpeedStir pill spins.

    Same here, though my pill has some black at the seams which Ieaves a little black dot on the bottom center of the vial. Cleaning the white residue off the sides takes a sheet of paper towel every other test sometimes more. Since I can still see the 10ml line even with the residue in there.

    The FAS-DPD test can turn it black. Do you use the same vial?

    No...I keep the 2 tests separate.

    Me too. The vial I was saying had the black on the bottom is the same as I use for all my other tests no salt, I keep that one separate.
