I have tried this procedure multiple times and everytime the solution turns
purple in the glassware filled with deionized water, even after rinsing in
running water for 2+ minutes. We do not have a dishwasher, so all the
glassware is hand-washed. Could there be a problem with our DI water?
We use the bromocresol and it does stay yellow if the pH is correct. We
also use a narrow range pH strip. You might want to check the pH of your
DI water.

Is bromocresol purple the same as bromcresol purple? The CAP question
regarding glassware cleaning refers to bromcresol purple, but I ordered a
powder and it is labeled as bromocresol purple.

What is everyone using to test their glassware for detergent residue? Is there
a ready to use solution or not?
