What are the most effective ways to clean an old tank?

[Aislinn]

Is it on the inside or the outside of the tank?

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

Don't know if it's available up in your part of the country, but there are 2 product's that can be safely used w/ good rising. 1 is called Lime Away & the other is CLR, both are pretty amazing, don't smell the greatest, ok the CLR down right stink's, but boy do they wrk in many dir. Both can be bought online if needed & they're safe for use on thing's that will be used by human's via consumption as in w/ glasses lets say, so w/ a good rise , I have had not come across anything that they have not wrked on.
P.S. where I live the water is so hard that it won't even register on an API test for GH, so theres always a bottle around the house
Both cleaners are very good, quick & safe in many other cleaning situation's
Let us know what does the trick, sure it will help many in the future

There must be a reason that no one mentions bleach. What is it?

bleach will disinfect, but won't remove heavy mineral deposits....I use sani- clean (industrial de-limer) it contains hydrocloric acid...It will remove the deposits....all you need to do is rinse....rinse...and rinse again
