Should I cut my phalaenopsis leaf off?

[angel415]

Hi everyone!
I was wondering if my leaf was worth sparing or if I should just cut it off. The thought of having to cut off ANOTHER leaf of my abused baby makes my heart sad.

This is a pic of it before:

I cut off the dry spots, which resulted in this:

Its been hanging on for the longest time - my orchid is a fighter. Do you think it can survive?

Theres also a little dark circle on the other leaf - should I get rid of that too? It's a little blurry: (http://i29.photobucket.com/albums/c2...5/DSCI0116.jpg)

......And if I should - how do I do it? Someone told me I can chop parts of the leaves off and then treat the wounds with mouthwash - is that true?

Tips appreciated. I just want my survivor to be beautiful again - not that it isn't ;-)
