I use a home made solution made up of purified water (75%) Isopropyl Alcohol (25%) and a few drops of pure teepol detergent as a surface tension reducer.... (wetting agent)
When I need to deep clean on my vintage SOTA RCM, I start with a wash/scrub with my DIY solution, and then follow with AIVS enzymatic cleaner, finishing with a rinse with purified water (every stage sucked off by the RCM) - but this is very time and labour intensive.... I am working on an ultrasonic solution that doesn't cost an arm and a leg...
Here are some other recipes:
This one is a close relative to the original Discwasher fluid (analysed some years back by an industrial chemist vinyl fan)
22% IPA (isopropyl alcohol)
78% Purified water
1% Wetting agent (Teepol, photo-flo, etc...)
2-3 drops Armor-All (original) per litre
The Armor-All has antistatic and lubricating properties (a number of people have experimented with Armor-All and similar automotive vinyl treatments on audio vinyl with exceptional results...)
For ultrasonic cleaners:
97.8% purified water
2% IPA
0.2% Wetting Agent
If you are looking for a treatment to increase record and stylus life (ie decrease friction) as well as anti static properties etc...
The commercial LAST and GruvGlide products are both excellent but these are vinyl treatments rather than "cleaners"... a different topic really!
bye for now
