After years of cleaning glass pieces with 99 iso and salt but still suffering from that hazey white film left in perc and water level lines in the tubes i have found a simple solution that worked perfectly, fast and easy! i tried 420 clean, iso/salt, simple green, CLR, everything over the years and none of it got the hrd water stains off
The film left behind is calcium and lime scale, typical hard water stain......CLR DID NOT WORK
THE SOLUTION = PH DOWN
PH Down will completely dissolve the white stain and rinses right out...just pour into the piece, i let sit about 30 min, then came back and shook around a but and rinsed out with a gallon of RO water from the room......Sparkling new!
The stain has to be dissolved by acid after it has dried and attached to the glass surface
TIP: Wear Gloves and Plug the pipe when shaking or pouring the PH Down - be safe
