Using G-Sonic Ultrasonic Record Wash Concentrate is easy. First, if you're using a regular gallon jug of distilled water, add ten drops of the G-Sonic concentrate. Put the cap back on and shake it for at least five seconds to mix well. Then pour the mixed solution into your ultrasonic tank and start cleaning your vinyl records. For HumminGuru users, after filling the bath tank, just add one drop of G-Sonic to break the water's surface tension and get better cleaning results. Before using the ultrasonic bath, it's a good idea to do a manual clean with G2 or G3 Fluid and a microfiber wipe. Store the G-Sonic concentrate in a cool, dry place. Keep it out of reach of children. And make sure to follow the recommended dosage to get the best cleaning performance and protect your records.
