I got an old tank and it's being reluctant to give up it's old look. I tried some vinegar but no go. I was using a scrubby sponge and a brush but nada. Any ideas?

Q
 
Sometimes glass can get etched from inappropriate maintenance,It may never look like new, that will be up to you whether the stains that can't be removed are tolerable....:dance2:
 
i use vinegar, baking soda, and a mr. clean magic eraser sponge. works like a charm on everything ive encountered!
 
I have a Mr Clean magic eraser... going for it now.

Yeah I know about etching and there is some but there is lime deposits that're being tough and a lot of below the waterline c*** too. I have had some success with the copper pot scrubber and the vinegar but I think I need something more. Steel wool doesn't cut it either. A razor blade takes off a small patch at a time with effort.

Well... I filled the tank with water to see if it leaks and I'm golden there. I emptied the tank and gave it a good scrubbing with pure vinegar and much of what was a couple of inches down came off. The top 2 inches though will not come clean and I believe most is etching. when filled with water its hardly noticable.

I use hydrochloric acid to remove lime deposits from glass in hard water areas. It will certainly work on a fish tank but rinsing would have to be good afterwards. Toilet cleaner would be great to clean the glass as it contains the acid and is thick enough to leave on the glass for long enough to be effective but also contains lots of nasties for fish. Glass is porous and will take in chemical applied to it to a small degree. It also will let some out to a small degree killing fish in the process. I would suggest if you are salvaging a tank then you would have to rinse and soak a few times afterwards.
 
Microfiber cloth

I use a microfiber cloth on my aquarium. It was used when I got it and had quite a build up. No chemicals - just water on the cloth.

It is amazing. I have used them to clean windows, mirrors, etc. for some time and now I have a cloth that is dedicated to my tank only.

They are fairly inexpensive and saves you the trouble of trying to properly rinse after using the harsher cleaners.

Give it a try.
 
Elbow grease. LOL
 
at the dollars stores in our area, they sell a bath room cleaner (pump bottle) that is basicaly a strong calcuim and rust remover (smells like clr).

what i am having trouble removing is a stain left from one of those plastic picture back grounds. it looks like an oil stain on the glass. anybody had this same problem.
