Record cleaning concentrates


Interested in the experience or comments of A'goners who have used any of the record cleaning concentrates currently available eg L'Art Du Son, VPI and/or Walker Audio Active enzymes. The concentrates all come in 1oz or 2 oz bottles that yield upto 5 litres of record cleaning fluid after mixing with distilled water etc.
With my rapidly growing vinyl collection and cleaning needs, the concentrates may be the answer as I am unable to secure supplies of the 16/32 oz stuff on a regular basis.
Many thanks for your help/recomendations etc
Cheers

I have tried a number of products. I have settled on the Walker Prelude 4 step system. It is time consuming but it seems to work the best. I hear a clarity that I haven't heard in some recordings. I have tried L'Art Dus, Record Doctor, VPI, Nitty Gritty and this is where I wound up. But I still will try whatever comes down the pike.
The Walker Audio Prelude 4 Step process here, after trying many others over many years. It simply works the best of any cleaning fluids regimen I've ever used (including most already listed above), and allows for a clarity and transparency of reproduction from the record grooves that I've not experienced before.

In amongst the thread's you will find very favorable comment's using an active enzyme soak first step application.
Other enzyme base brand's are also available on the market.
I happen to use Walker's solution.

I'm in total agreement with Rushton's experience with the Walker Prelude and Step 4 final rinse.

This cleaning solution is everything as advertised backed with a full refund if not satisfied for any reason.

Most definitely Lloyd Walker's solution is something you have to try.
