Brake fluid

Is it the case that once a bottle of dot 4 fluid is opened it should be used or chucked ?
Can it absorb moisture to such a level once the foil seal is broke that it becomes quickly contaminated? The lid is far from air tight you see.
I bought a bottle about 8 months ago to bleed my front brake. The lever is still solid now.
I bled the rear about a month later and for the last couple of months the lever has been getting closer to the grip. I changed the pads the other day and re bled it and I just can't get the lever as solid as the front still is, don't get me wrong is is great and the bite point is well off the bars but I reckon it will back up pretty quick.
Would I be better off getting some fresh fluid ? or perhaps will I just never get the rear as solid as the front because of the length of the line ?

if it is kept sealed it can last for some time.
I am actually using some that i bought quite some time ago."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

I don't think the lid is very good. I can't tighten it very well. It just clicks, cross threads and is loose again. It isn't a big issue, just wondering. I've got no leaks or anything, pads wear even and everything.0
