How do I make probe cleaning solution ?

Are you talking about a pH probe? If so, soak in vinegar overnight, rinse and re-calibrate.

Straight up vinegar, overnight ? tslking about ph, orp, and salinity probes.

Yep, straight vinegar (typically 5% household vinegar) overnight will do it. If not, you've got probe problems that cleaning won't fix.

Seem harsh . So what‘s in commercial probe cleaning solutions ?

 

[redfishbluefish]

If you don't like vinegar overnight, you can go with 5% HCl for five to ten minutes....but handle with care.

As far a commercial cleaners, not sure what's in them. In chemistry, because we are measuring pH of various compounds, the cleaning is acid soak / base soak / organic soak (ether or carbon tet.). But because our probes are simply seeing saltwater, the acid soak should suffice.

Ah, that;s part of what I read on google today. and the vinegar will not harm the other probes, the orp or the salinity ?

Vinegar is not harsh at all. The methods recommended below use bleach or much stronger acids than vinegar.

Just don't physically rub on the probe.

The other two probes are less delicate than a pH probe. Vinegar cannot hurt them either.

Does a dirty ph probe malfunction or does it skew reading, high or low?

Can I calibrate a dirty probe and have it read accurately/correctly?

My logic is, it's going to be dirty more than it's clean. And I'm lazy.

When I remove items from my sump to clean, most just have a light film, even stuff I haven't cleaned in many many months.
