Ear Piercing

My daughter (11 in August) has been asking for a while if she can have her ears pierced.  When she mentioned it around Christmas, I said it would be better to wait for the start of the summer holidays, and now of course they are nearly here!

I can't remember exactly how old I was ... around 12 or 13, I think and I know I was responsible for remembering to clean them every day.  Even though I have told dd about this, I'm not convinced she is prepared for this part of the process.

What is the recommended 'fluid' now?  I'm sure I used TCP but is salted water good enough/better?  I read somewhere on the web to use hydrogen peroxide, but that seems a little extreme to me.
