Premium distilled water for ultrasonic record cleaner

Rlawry

a very large % of my records are new or mint / mint -

perhaps an identical ultrasonic machine with cheap distilled water (like I was using) for old records

great point, sorry I couldn't resist having fun

Only ever use premium quality oxygen-free, cryogenically treated, zero ion pure, RoHS compliant 100% H2O variety water.  Only use that water after all the bad electrons and lithium grease has been filtered out.  Don't use cheap imitation water. 

For best results, use water that has been removed from vacuum mines after vacuum mine implosion accidents.  Many think that idea sucks, but performance is much better than artificial H2O.  Compliments will rain down.  Using artificial water will result in low performance as will artificial vacuum. 

Don't use water on mint records because everybody knows that mints melt in water.

To Rlawry's point: I pre-clean virtually every record that goes into the ultrasonic, to reduce the amount of contaminants that pollute the bath. There's no 'one way', but using a conventional vacuum record cleaning machine with appropriate fluids, followed by a pure water rinse, is a predicate to the next step of cleaning in the ultrasonic. I buy a lot of old records, and even with pre-cleaning, change the ultrasonic water out at roughly 50 cleanings.

Seems there is no end to the 'truth' of water.  Yes, it is in the 'hearing' the difference, if you can.  But better yet, a true audiophile will want to see 'clean'.  For that you must put an electron microscope in play. I know, I know they cost mega bucks, but if you are 'serious', like Al Porter, cost would not be important.  The 'purity' of the matter should not be important.  Remember, it is all about the music.
