How to tell if glass is etched or water-marked?
I have attacked this glass with vinegar, razor blades and CLR. The marks still remain around where the water line was. None seem to be having an effect. My thinking was that as the marks were around the water line that it would be mineral deposits. But I cant get this glass clean. Could it be etched?

Nice tank John. What dimensions is that?
Vinegar soak for a day or two didn't work? |

How does it look with water in it? Clear?
My experience vinegar soak and razor does the job. Seen that on acrylic but not on glass. Hope you get it off. |

visible even with vinegar
tomorrow I think I am going to experiment with creating a little dam area using plumbers putty and then filling it with muratic acid. |

Try CRL. Put it on a paper towel and and lay the soaked paper towel on it for a few hrs keeping it wet with CRL.

Muratic acid is strong. Hope it works.

However, you have to be careful with acids and glass. If you are working on the tin side of the glass, many acids will react with the tin embedded in the glass, causing a "gray haze." Some recommend mechanical polishing to remove these stains. In most cases, after spending time ad infinitum, polishing will probably work quicker. In many cases, the only way to get rid of the stains is to replace the glass. I would not spend much time on it, in the end, it is pretty much a wasted effort.

Be VERY careful with hydrofluoric acid. In fact, I would recommend not using it at all unless you have the right equipment and experience with it.

Muriatic Acid did nothing to the haze. I think this glass is heading towards the trash can.

There are a number of automotive glass polish kits available that you can try. They are just a polishing compound that removes scratches and stains. If you are are the point of giving up, its worth a try.

I have some turtle wax heavy duty rubbing compound. I have also heard about diamond powder and cerium oxide. Going to check with friends to see if any have an orbital sander I could use. Thanks all for the comments.

Most autopart stores (big name) carry the products and they are inexpensive. Some of the places will rent the tools you need.

Dude, I have the same problem only my tank is 8 months old. Im waiting on answer from the manufacture.
I hate to tear down my tank and looking for a way to buff it out as razor blade is not working. I know its been awhile but did the cerium oxide and sander work? |

I converted a peninsula tank to an external overflow. The glass was etched behind the old drain/overflow, once I cleaned it up and filled it with water, you can hardly tell it's etched.

I am starting to think my tank has calcium carbonate precipitation on the 2 low iron panels.
I have the seaswirl hitting these 2 panels I had the 2 part dripping into the return pump chamber but flow was not turbulent enough! Tanks started developing 4 months after setting up. I tried to clean with vinegar and razor blade but dont' think it made much of a difference. I can't see a tank from Coast to Coast being etched below waterline after 6 months!. anyone else can relate? |
