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.

Dawn dishwashing liquid should remove any waxes or oils on the CDs.  You might also try ROR - residual oil remover, a liquid made for cleaning fine camera and microscope lenses.  It's available from Amazon or most camera stores.  But the Dawn should be fine.  
Dawn is the go-to product for auto detailers that want to strip the old wax from cars before a detailing.  Very good on windshields to remove the greasy buildup that makes wipers streak.  It's also good on dishes.  
Dawn is better for this purpose than a different brand? I was going to use some biodegradable stuff from Costco.
Dawn is used to remove oil/grease from roadways after accidents. It really does its' job. Even animal rescue organizations use it to clean off animals caught in oil slicks.
In fact, if you do use it, be sure to apply some skin moisturizer to your hands when you are finished cleaning CD's as they can get a bit dried out, as well.
