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.

In fact, I've been thinking about getting a demagnetizer, such as the HiFi Tuning or Furutech. I've experimented enough with various tweaks to know that they do provide a benefit. But I wish I could hear the demagnetizer, considering the cost. And I presume it's true that there will always be some residual effect from the previous treatments. But now that I've seen that there really is a benefit to these spray treatments, I want to think more carefully about what I'm doing before I go any further. I think I might just stick with Shine-ola. Or I might take one last stab with the L Art du Son.

Finally finished cleaning the CDs. I put them through three rinses in distilled water after washing with Dawn. What a chore.
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.
