Windex contains ammonia. Ammonia is toxic and corrosive to vinyl. Keep using Windex and it will destroy your albums. This is no secret.
The accepted cleaning formula (in various doses but still the same formula) used by most any reputable company is 75% distilled water, 25% denatured alcohal, and just a drop of DAWN detergent (or similar agent like Kodax film developer - name escapes me). Why alcohal? It removes residue on and in the grooves. Why distilled water? It evaporates quickly while being the transport for the DAWN. Why DAWN? It is the agent that allows the alcohal and water to penetrate deep into the grooves, as opposed to just bubbleing on the surface. Don't EVER use ammonia or anything corrosive on record vinyl. Record vinyl can easily burn and/or transform and morph under heat. Ammonia = heat. Heat = bad for records.
shame.. :nono:
