CD Tweaks and Longterm Damage

I was reading the blurb for LAT International's C Diamond CD treatment. They bragged that it has a ph of 7, while some other tweaks they have tested have ph values as low as 5. The latter they claimed would damage CDs over time, just like Armorall did for those who used it.

Has anyone tested the ph levels for Optrix, (new and improved) Auric Illuminator, or Vivid? Do any of these pose a longterm risk for CDs?
