I believe goofyfoot accidentally left out the word "not" between is and recommended. |
I asked Okki Nokki about their cleaning solution and they answered this:
"
We always did have 4% to the litre. (4% in the finished 1 litre, made out of the concentrate. Above 20 % to the litre, the alcohol is getting negative influences. We do only 4%." |
elliottbnewcombjrI don't know what is in that Fisher Scientific Versa-Clean formulation but I believe it is designed for glassware. Personally I wouldn't use it on LPs but if it works for some people it might be ok. I wouldn't worry too much about the plasticizers. As long as you don't soak your LPs for excessively long periods of time, they should be ok. The surface of an LP could loose some plasticizer but it would take a lot of exposure to totally remove plasticizers from the bulk of the LP. I always tried to take the simplest approach to cleaning LPs, distilled water and isopropyl alcohol. If the LP is really dirty (especially oils from finger prints) than use a commercial cleaner or an ultrasonic cleaner. Some of these cleaners can cause more problems than they solve. |
Isopropyl Alcohol (IPA) does an excellent job and is quite safe unless mis-used. Do a Web search on "vinyl
chemical compatibility". There is lot's of information available for
those willing to do a little homework. Here's one chart: https://www.calpaclab.com/pvc-polyvinyl-chloride-chemical-compatibility-chart/
You'll want to use the purest IPA. It is available 99% pure.Here's what I use: https://www.amazon.com/gp/product/B005DNQX3C/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1I mix 1.3 cups of the above along with 0.9 tablespoons of Ilford Ilfotol photographic rinse agent in ~ 3.3 gallons of distilled water in my Elmasonc P120h USC.
The IPA+Ilfotol+Distilled H20 gives a very 'clean' solution, measuring at 0000-0001ppm total dissolved solids (TDS).
If you're considering chemicals such as Versa-Clean, it's wise to check TDS. Same for disinfectants. They add more to a solution than you'll take off a record. Keep in mind that anything in the water on the record when it dries will be left on the record. If you're thinking about using
L'Art du Son, be aware that this is not really a cleaning agent. In reality it is a coating for the record surface not unlike Gruv Glide to "lubricate the groove". It will leave a nice and shiny coat. Thanks but I"ll pass. YMMV. https://thevinylpress.com/timas-diy-rcm-follow-up-2-compelling-changes-improved-results/ . |
