Clean away old CD treatments


Hello,

Recently I've been trying various CD treatments. I began with Optrix, switched to Shine-ola, and even tried Ultrabit. A few of my CDs have received all three treatments without any cleansing in between.

I would like to start over. I want to clean all the old treatments off my CDs. Is it enough to use mild dish soap and distilled water? Or should I use something like Novus? I am hesitant to use lens cleaners with isopropyl alcohol or ethanol because I've heard alcohol is bad for polycarbonate.

Would appreciate any advice.

Actually there were not 50 discs, but 150. Long day.

I left four discs that had received only the Ultrabit and four discs that had received only the Shine-ola. Listening last night, I think the Ultrabit treatment might be mellowing over time. It doesn't seem so aggressive now. The clarity and detail are very compelling.
Clark Johnsen did a review of quite a number of CD treatments for Positive Feedback titled Lotions Eleven. 

Rfprice, I bought the Hifi tuning demagnitizer. As I said, I was skeptical, but thought 'What the heck'. Well, I was surprised when I and my friend noticed a significant difference when comparing the discs before and after.
If you want, you can borrow mine. I have been indulging in streaming music for the past 6 months. I love it.
