Record Cleaning Machine Fluid

Was RRL purchased by MFSL?
I just searched in MusicDirect for RRL products and it looks like MFSL is either rebadging or now owns RRL.

Any information on this?

-Thanks

My regimen has been:

1. RRL Super Deep Cleaner
2. RRL Super Vinyl Wash
3. Steam Rinse.

This weekend I tried the Audio Intellegence process and, introduced Vinyl Zyme (formerly Bruggtessel) into my RRL process. I'm going to try the Vinyl Zyme & RRL process until all my stock is gone and then switch to the AI process. I think that seems to work pretty good.

A member here, TRAUDIO, distributes for Audio Intelligence.

Is the order:
1. Vinyl Zyme
2. RRL Deep Cleaner
3. RRL Vinyl Wash ?

Or is the Vinyl Zyme in between the 2 RRL applications?

Anyone recommend a really good brush for a diluted detergent wash, as a very first step ahead of the above, if the vinyl is so dirty you don't want it to get near your RCM.
I have seiously water damaged LP's...occurred 10 years ago.

Music Direct sells the MFSL record cleaning brush . I use three of them in the Audio Intelligent process. I like them so much, I don't even bother with the automatic feature and brush on my VPI 17F RCM.

DO UOU NEED THE CHANGE BRUSH EACH STEP?
