The Concentrate Your Ultrasonic Record-Cleaning Machine Needs: Mobile Fidelity Sound Lab Ultra Record Wash Helps Get LPs Clean and Quiet, Mixes with Distilled Water to Form Unbeatable Solution
 
Specifically designed for use with ultrasonic record-cleaning machines, Mobile Fidelity Sound Lab Ultra Record Wash concentrate helps get your LPs as clean and quiet as possible. Sold in one-ounce bottles, this audiophile fluid is easy to use and will get you on your way to hearing more music and far less noise. 
 
Simply mix the contents of an entire bottle of Ultra with one half-gallon of distilled water. (For best results, substitute MoFi Pure Record Rinse for the latter.) Once the solutions are mixed, pour the combined fluid into your machine's tank. Replace Ultra in your tank and re-mix with water after you clean 50 LPs.
