From the Manufacturer:
G-Sonic is a special ultrasonic wash formula that offers a more pure and focused blend of additives than can be commonly obtained off the shelf. The result is greater groove penetration for a superior ultrasonic cleaning.
Add ten drops of G-Sonic concentrate to each gallon of distilled water. Replace the cap and shake for at least five seconds to mix. Add the mixed solution to your ultrasonic tank and proceed to clean your vinyl records per your desired methodology. A one ounce bottle of G-Sonic will make up to 60 gallons of ultrasonic bath.
