Hazy glass, can you help?

[Phatboydime]

Well I picked up this 55 from a coworker in trade for some manual labor. The only thing she knew about it was that it was once a saltwater tank. Other than that she had no idea what it has been through.

I got it home, and started cleaning it up. Found out that the top trim was loose, and ugly too boot, so I removed that to clean under it, and easy my glass cleaning work. The bottom trim will likely be discarded as it is broken, ugly, and useless.

Before I cleaned any glass it looked like this.

I cleaned and cleaned, scraped iwth a razor, wipped down with vinegar, then goof off, then alcohol, all to no avail. I cannot get this haze off the glass. Im starting to think its IN the glass, like etched.

The thing that perplexes me, is when I wipe it down with the alcohol, the glass looks crystal clear, but when it drys, this haze comes back, and yes the haze is on the inside.

Can anyone help me.:help:

I would try applying the vinegar full strength to the glass and let it sit on the glass for a while before rinsing it off. The acidic effect of the vinegar will take time to work on the deposits, it won't be quick. This is not a wipe on / wipe off type application. If you let the vinegar dry out completely you are back where you were before applying it so lay the glass flat to use it and rinse it before it dries out.

when there is water in the tank, you might not even see that.... have you tried to see if it leaks yet? When you try that, you can also judge if the hze shows then...

Thanks, No I havent filled it up yet. I have to redo all the silicon, its all bad. Once that is done though, I will fill it up and see if the haze remains. Im also going to try letting the vinegar sit on the glass for a while, if that doesnt work, I may try some 0000 steel wool and glass polish that I use on my chrome for my motorcycle.

Thanks again.

To keep the vinegar from evaporating off the glass, I like to soak a towel with the vinegar and lay that flat on the glass...seems to hold the moisture better/longer and it soaks the glass evenly instead of the vinegar puddling up in spots. Good luck!

One of my old saltwater tanks started to haze. I used full strength vinegear and a razor blade. I was able to get it off. Mine was cause form algae growth and calcium deposits. The longer the tank site dry the harder it is to remove.

huh... you sure the glass is scratch proof? some glass is barely resistant to scratches... try using the razor blade to scratch is as best as you can in an unseen part(behind the edging will work)
