Walker prelude vs. Audio Intelligent

OK. Thanks to all for the input. I'm impressed by Walkers fresh enzyme approach, 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? After all, my approach to vinyl is like a doctor-patient. First, do no harm.

Gpgr4blu and all, there is no residue left on the vinyl after using the Walker Audio Step 4 Rinse and no risk to your vinyl from the minor amount of alcohol.

Disclaimer: I'm certainly not a chemist, just a dedicated vinyl lover who's used a lot of different cleaning fluids on my LPs over 30+ years.

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
