Hi Duane,

Is your buffer modification a base (i.e.    pH > 7)?  If so, is the modified cleaning solution available as a concentrate?  Also, will the modified solution work with shellacs?

An important precaution to add to your suggestions regarding "dust", we don't use the same brushes with shellacs and "acetates" because shellacs can shed abrasives that can damage the surface/grooves  of acetates.

Hi Eric,

As you may know, we have also modified our Miracle Record Cleaner to improve performance when dealing with “heavy” palmitic acid residues.  This is accomplished by using a carefully selected , high-purity buffer to deal with pH change caused by the larger deposits.

To my understanding, the LOC has found this a useful product.  Our own instructions offer a simple, effective approach to dealing with any “dust” left after rinsing & air drying.  It’s the same instruction one gives for handling disc media before & after playback:
Apply a carbon fiber brush to vinyl surfaces before & after playback & use an appropriately configured crushed velvet duster for shellac, acetate, lacquer & Edison Diamond surfaces.

The thread is used to maintain a gap between the suction head and the grooves - the thread doesn't actually clean the grooves.  The thread spool is on a slow continuous gear motor, so new clean thread is continuously in contact with the disc surface. The thread is fine, synthetic, and lintless.
