Cleaning testing beakers?

[chayne]

i was curious how everyone cleans their test beakers? i am getting a white haze on mine. was curious what people use to clean this off?

I think that is just a reaction of the plastic to the testing chemicals. When it gets too bad, you buy new vials.

Or get glass vials, but that can have its own safety issues around pools ......

I have had some luck using a paper towel to wipe the haze off the vial. I also get some dark marks from the stir bar from one of the tests. Paper towel also removes it.

Muriatic acid cleans pretty well. Just be super careful with the acid.

I rinse then paper towel dry the test vials right after use. I'm going on my third season and they are still pretty clear.
