To use Auric Illuminate or not.

One last thing:  I treat the discs while I'm listening to music.  It gives me something to enjoy while taking the time to fully treat each disc.  To do a group of 9 discs at one time, I averaged about 90 minutes to do all steps to the 9 discs including some time to let the marker and the solution dry.  This only has to be done one time for a disc with the newer AI II formula.  comes out to about 10-12 cents per disc to do this.  The sound and picture (DVD's) is transformational and will keep you motivated.  It makes poor to average discs sound way better than you would have thought they could sound and good discs flat out great.

Auric is the real deal as far as I'm concerned. It does what it says it does.

My experience with all of the many disc treatments I have used (including Auric) over the decades was that eventually they all oxidize, which I easily heard as a dullness, which makes sense as the treatment becomes somewhat opaque, making it hard for the laser to read

Instead I wash all discs in distilled water and a mild soap solution

Update on Auric Illuminator II: I have now treated over 850 discs with just one kit, plus needing to buy an extra pack of 10 Staedtler chisel tip black markers. The pack of ten markers cost $17 including shipping. Each kit comes with only one of these markers. So it has cost me some time and $67 dollars to do all of them. That works out to be about 8 cents per disc to get much better sound and even picture quality with DVDs, Blu-Rays, and 4Ks.

Again, you just need to treat them once and the improvement stays that way indefinitely.

Treat both sides as the directions tell you.  You ONLY use ONE drop of the fluid per side.
