I have had success using lime and rust remover. I don't recall the brand name right offhand.
Thanks so much for that information.
IDilute the lime remover with water and apply it to the affected glass. Let it sit for a while, and scrub with a dish scouring sponge.
What is your "procedure"/ratio of dilution? I.E.: Amount of water to chemical.
You may need to repeat the process for heavy deposits.
In my case, repeat, many many many times.
Rinse THOROUGHLY before putting herps in the enclosure.
That is for sure. Thank you, for the reminder.
Amphibians in particular are very sensitive to chemical residues.
Yes, that is for sure. That is the part that worries me the most, since, they are for Anura tanks/vivariums. Also, I am a "giant worry wort", in general.
Thank you, for your time and attention on this matter.
Vinegar (acetic acid) is a good, "non-toxic" acid that will remove mineral deposits using much the same procedure outlined above.
I think that I would feel better trying this method first. Since, it is for Amphibian vivariums.
Some spots may be etched into the glass and may not come off.
That is a fantastic point. I would be happy to just remove fifty (50) percent of them. Yes, I had that many!

Thank you, for your time and attention on this matter.
I would also like to ask you both and anyone else that might know, is human toothpaste good for removing water spots on glass? If so, what brand/type do you recommend?
Thank you all for looking.
