... plain distilled water does not do anything. It will not clean your records ... It won’t remove grease or fingerprints. You need to use 1 1/2 ounces of isopropyl alcohol (70%) per tank and a surfactant to properly clean records when using an ultrasonic machine.That’s certainly not universally true, even though it may be true with the machine you are using. The Klaudio US machine uses nothing but distilled water and is very effective with grease and fingerprints. That’s all part of its charm: Ease of use. Essentially one button operation.
