Walker prelude vs. Audio Intelligent

... but AI seems to present less of a problem in terms of what is left on the vinyl at the end of the process than step4 of Prelude (although there appears to be a method to Lloyds madness). Any chemists have an idea as to whether a small amount of alcohol in last application can lead to any dryout or breakdown of vinyl?

Please excuse, I don't mean to be contentious but I'm not following. What is it that AI leaves less of? I thought you had not tried either cleaner?

I have not tried either cleaner. According to the info in various threads and the products websites, the final rise with AI's last step is pure de-ionized and highly filtered water whereas Walker has a very small amount of alcohol and another ingredient in the 4th step rinse. These ingredients, I surmise, may be left on the vinyl at the end of the cycle. Of course it is possible as well that the alcohol and extra ingredient is not left behind or left behind in such amounts as to not have any impact whatsoever on the vinyl even over the long term. That's why i referenced chemists in my latest query. If you have LLoyd's ear Jtimothya, I'd love to hear the theory as to why the final rinse is something other than pure filtered de-ionized H2O. What's the upside and downside (if any) to additional ingredients?

You are correct with your speculations,

LLoyd Walker has a history of failed and reckless attempts to improve vinyl play back.
Walker's product's are nothing but snake oil.... and his turn table and arm! geez

I confess, LLoyd payed me to hype his product's.

Stick with your Disc Doctor cleaning fluids, they leave nothing behind and have no harmful ingredients

I have a question: is it worth using the full Walker regimen on brand new vinyl? I've been purchasing old sealed vinyl (and brand new pressings as well). I'm just wondering if I'd be wasting these precious fluids on them or whether it's just as applicable.

And do any of you ever use Last preservative?

Has anyone compared steaming with any fluid regimen head to head against either of these two systems alone. Reading a post like this tempts me to try the Walker system but then when I consider the price and the success I'm having with Disc Doctor, Steam and type I reagent grade water I find myself sticking with my less expensive and quicker regimen. Also, is the Walker enzyme mix available separately or does it have to be bought with the rest of the system?
