Hi Eric,
Good to hear from you. On an as needed basis, I do recommend keeping brushes used on acetate & shellac surfaces separate. When customers are not interested in a second pair, I recommend cleaning acetates first or changing the pad before cleaning the acetate discs.
The modified MRC uses a high purity, biological grade buffer that operates above pH 7. The LOC has been sent this solution as have a number of the List members. We’ve had very good responses from users. The buffer is expensive even when used in modest amounts & that price is reflected in final price.
Regards,

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.
