Cleaning Hanna tester vials

[SpikesReef]

I have a hazy film on the inside of the vial that woke come off with water alone. I am going to clean with RODI immediately after testing from now on.

Does anyone have a process or solution that will clean these vials?- aside from the $25 Hanna cleaning solution that Brs sells?

I have the same issue lol, try a tint bottle brush? Or an alcohol/acetone solution?

I was thinking denatured alcohol. I do glass work and we use it to clean newly cut glass. Not sure if it'll leave a haze though

Vinegar is always worth a try. I know it works on my Red Sea Mg test vial.

I would love to know how to clean them. I have the same haze on my dkh checker. I have always clean right after testing but that still does not help

Here is the link to what I generally do...it has kept the haze off of my test vials pretty well...also a clean soft absorbent cloth to dry them off with helps....if they start to get hazy in the inside I fill them with .1M HCL and let them soak for a day or two...
