What's the best way to clean PH Probes?

[budsreef]

I pulled one of my PH Probes to re-calibrate it and found it has grown some of the same stuff on it that grows on the glass if left alone. What's the best, safest way to clean them? Would it hurt to soak it in vinegar water? Thanks for any and all inputs.

Stuff as in coraline or stuff as in algae? If it's calcerious, I'd say vinegar. It's a pH probe, so acid isn't going to hurt it.

Soak in vinegar overnight then clean it off good in RODI, recalibrate and your good.

Ok, thanks! I'll try the vinegar.

I used a dental pick to scrap it off. Takes only a minute or so.
