Cleaning cd lens ?

You're welcome, but 70% is not pure and I wouldn't trust their definition of "water" (yes I'm a cynic from way back :). Use what you want, but I have only ever used pure isopropyl (which you generally have to ask for) or pure acetone, which you can find on the shelf.

Good luck and hope you get it working right!

Danmyers...The distilation process used to make alcohol yields about 30 percent water. It boils off and condenses along with the alcohol. So the water is distilled, and you don't need to worry about it.

Eldarford - I never worry about it 'cause I only buy pure :)

Me thinks you're talking about the process of making alcohol and I'm talking about the process of marketing alcohol. I buy pure to be assured there is no difference between the two.
