Disc Doctor has been using this solution for almost 20 years and selling it to customers upon request for the last 6 years. It does not leave residue on the stylus or cantilever.

Stereophile Review of Disc Doctor Stylus Cleaner
"Goldman, a chemist, claims that his stylus cleaner, a mixture of micron-filtered water and separately micron-filtered +99.5% 1-propanol alcohol, leaves no residue on the stylus or cantilever. He's not comfortable with those that do, whether accidentally as a result of impurities, or deliberately, like SPT...In an A/B listening comparison of the fluids, I was surprised to hear, after listening to a passage with the SPT-cleaned stylus and repeating with Disc Doctor fluid, a slight bit more sparkle and extension using the latter... Given the price difference, I don't see how you can go wrong with the Disc Doctor fluid..."
