Hdm's guess re: alchohol is interesting. Inaccurate, but interesting! Neither RRL fluid contains any alchohol. Never has, never will (this according to Brian Weitzel, who makes it). Otherwise I agree with Hdm's post.
SDC contains higher levels of surfactant. That's why it's more effective at removing mold release chemicals and stubborn dirt. It should be the first step, or at least not the last step.
SVW contains only trace amounts of surfactant, and also a vinyl lubricant that leaves no sonic signature (IME). It should always be the final step in the record cleaning process. The next thing that hits the record should be a stylus.
