The cloud point is an interesting property of Triton X: I studied college level chemistry, and generally speaking, I thought most substances/chemicals were more solvent as the temperature of the solution increases. But with Triton X, having a cloud point of 25C indicates that Triton X becomes more insoluble as the temperature increases above 25C. . .
Ultrasonic record cleaners
I have a modest lp collection, mixed bag of original college age purchases, used records before the current renewed interest, and some newer albums to replace some older issues from the p mount needle days. Have a vpi 16 machine and audio intelligent form 6 fluid. I’m not finding a significant improvement on my noisier issues. The price of ultrasonic cleaners have come down to a price I would consider. Appreciate the experiences of those who have purchased the ultrasonic machines, are they superior to my vpi and are the less expensive models effective?
TIA

Cloud point is not unique to Triton X (100 or 114), it's a property of nonionic surfactants, the book: VIII.2.4.c Nonionic surfactants for the most part do not ionize in aqueous solutions so that the hydrophilic head has a neutral charge. A unique property of nonionic surfactants is “cloud point”. Cloud point is the temperature when the mixture starts to phase-separate, and two phases appear, thus becoming cloudy. The cloud point is the (theoretical) optimum temperature for nonionic surfactant detergency, but above the cloud point the surfactant comes out of solution and detergency drops. |
I received one of the inexpensive ultrasonic clears, as sold on Amazon, as a gift. Looking forward to trying it. Can anyone recommend a cleaning solution formula, using readily available products that are available in typical US retail establishments? Distilled water is easy (grocery store). What about a surfactant, detergent or alcohol? I've been using a spin-clean for years and have spin-clean cleaner concentrate (if recommended). This will be my first attempt at using an USC. |
@reubent I use the recipe shown here with success. I then do two rinses with a vacuum machine. https://positive-feedback.com/audio-discourse/rushton-paul-diy-approach-ultrasonic-cleaning-lps/
