suggestions for cleaning glass

If its on the outside of the tank...maybe try CLR - Can you get that in Ohio? Its called CLR - Calcium Lime and Rust Remover - it is used for soap scum, and hard water stains - works wonders on shower doors. Its readily available here in GA - not sure if its available in OH though?

 

I concerned that the magic eraser took paint off your car and don't know if that would result in scratched glass. We do have clr I should have thought of that. I will try it in the morning. Wish me luck.

 

So, the CLR has somewhat worked. It is not so noticeable. still not sure about using the magic eraser. Anyone ever used that on glass before?

 

Sounds to me like the glad may be chemically etched. If that's the case, only polishing will get it out. But polishing it deep enough to get to new glass may distort the area.

so i have tried putting a vinegar soaked rag on the spots with no success. Thinking of trying this bleach solution. Any ideas on how much to mix?

Also thought maybe a baking soda scrub of sorts might work? Anyone ever tried anything like this? or anyone think this is a bad idea? The last thing i want to do is damage.

Any suggestions are appreciated.

 

If the glass is chemically etched, rubbing compound may work. The same stuff you use for car paint. It may take alot of rubbing.

 

Are you talking like wax? if not you will need to elaborate what i would need to get.

 

Rubbing compound. Any auto part store will have it.

 

So i was concerned with scratching the glass by using a razor blade any harder than i had to begin with, so I got a new blade and carefully scraped some in a less conspicuous place and started to have success. So after 2 1/2 hours of tedious scraping, you cannot notice the marks from across the room any longer. I do believe it is etched a little because as i said 2 & 1/2 and it still has marks on it. The good news is, if you didn't know it was there before, you probably would never notice it now.

I really appreciate everyone's help/recommendations. I did try all of them except the last one here about rubbing compound because by the time i saw the post, I had finished my aggressive razor scraping campaign. Thanks again!
