I rinse with Distilled water.
I do not use isopropyl alcohol because a chemist friend claims alcohol dissolves plasticizer molecules and can make the surface of the record brittle raising the noise floor. I also found that using alcohol increases record static.
I use a device I designed and prototyped myself using a special bristle material that I prefer. It’s a mechanical agitation system.
Sometimes, for moldy records, I use TTVJ Vinyl-Zyme Gold. It helps quiet records by removing light mold infestation. It will not fix mold damage.
I believe Liquinox (from Alconox) is a concentrated, anionic detergent good for manual and ultrasonic cleaning. I talked to a tech rep at Alconox and he said it is perfect for vinyl record cleaning.
