Record cleaning solutions containing "alcohol" can be used safely on shellac pressings provided wise choices are made with respect to the water soluble alcohol in question & its concentration in the working solution. It's been demonstrated for over 25 years that safe & thorough cleaning of vinyl & shellac pressings can indeed be accomplished with a carefully assembled water-based formulation of surfactants & wetting agents. Repeated & extensive listening evaluations have clearly demonstrated the value & safety of including low concentrations of a specific, reagent grade, water soluble alcohol in surfactant mixtures specifically developed for the cleaning of vinyl, shellac, acetate, lacquer & Diamond Disc surfaces.
The purity of methyl, ethyl, n-propyl & isopropyl alcohols readily available to the general consumer should never be assumed safe for use in home brews regardless of the amount used.
There are an endless number of ways to "clean" phonograph records, very few are thorough & safe. Thorough is an audible step beyond good.

You can spend much more money on much more elaborate fluids carrying elaborate claims (some more scientific than others). You can also wash records in a sink and get good results, especially with 78's. Again, some will scream and cringe at this practice. There are also numerous home-brew recipes on the internets, again some hazardous and some proven to work.
