Liquid solutions leave a deposit in the grooves. A weak soap and water solution leaves a slight covering when it dries.  A carbon fibre brush can be used before & after playing. Or a specialist cleaning cloth. But either of these record cleaning methods involves touching the record surface. A non-contact method of dust removal is by a vacuum cleaner, but that won’t clean to the very base of the record groove.

As any self-respecting audiophile knows, the less physical contact anything has with the face of the disc, the better but most cleaning methods require some kind of rubbing or brushing. In an ideal world, the only item to ever touch the surface of a record should be a stylus.

The new method is the use of an ultrasonic record cleaner. This ticks all the boxes with regards to non-contact with the surface of the record and they can be cleaned very thoroughly without chemicals. Microscopic dust particles are cleaned from the very bottom of the record groove.

How to use the machines with vinyl records.

The photo shows the deposit in the tank after cleaning 27 records.  

Usually, put 5~6 records in at a time,   soak the vinyl for a quarter of an hour or more while the cleaning fluid warms up to 33 degrees centigrade and then turn on the motor and wait for about 10 mins, no need for any rinsing.  The motor will brings records rotating by 5~6 rpm.

If the LP is very dirty,    pure water + anhydrous ethanol (drugstore buys 95% alcohol) + 0.25% isopropanol (can not be added, only for particularly dirty records, available in chemical reagent store) + surfactant (can be replaced by neutral detergent)

Percentage: 62% water, 30% ethanol, 8% isopropanol, plus 1ml neutral detergent

If the Lp records are not too dirty,   just add 500ml absolute ethanol into the tank, then add pure water up to the waterline, and then add 1ml neutral washing liquid.
