I purchased the Walker deluxe Prelude kit from a local dealer.
He told me straight up...follow the directions, clean a few Lps, then play them.
If you do not hear an improvement or do not like this cleaning solution for any reason, return it for a full refund.
Off the top of my head.
The prelude deluxe kit comes with three directional brushes with replacement pads and a tray to set them in as you go through the cleaning steps.
A small jar of active enzymes, a mixing bottle,with filler lines marked on the bottle, two sized very tiny spoons to scoop the enzymes for mixing, depending on how many Lps you want to clean.
This is to be mixed with the supplied laboratory grade water.
A bottle of liquid cleaner for the second step and a bottle of laboratory grade water including extra lab water for rinsing.
Also you get a nifty 6 inch cobalt blue ruler in case you need one.
There is nothing complicated with using this method of cleaning at all.
I have cleaned quite a few Lps, I'm just starting to get low on the lab grade water, I also use it to wash out the brushes.
Anyway, $135.00 for the kit is expensive, however I was offered a full refund on the initial purchase.
