Chlorine Test Vial Getting Cloudy

[HowardL]

I have had and used my new test kit for just over a week. I have noticed that the 10ml line on the test vial used for the FAS-DPD chlorine test is getting a cloudy appearance to it. It's actually getting harder to read the exact line.

I assume that I am missing some critical step in cleaning or otherwise caring for the test kit vial, but don't know exactly what it might be. Any suggestions? Thanks.

Found my answer...

"Over time, it is common for a cloudy residue to build up on sample tubes used for FAS-DPD chlorine testing. The residue can be removed by filling the sample tube with bleach, letting it sit for several minutes, rinsing, and then wiping throughly with a paper towel."

Thanks.
