4. There are often salts such as sodium chloride carried in from sea spray or on skin fragments, and sharp gritty silica crystals. In this chemical mixture are the spore of countless moulds, fungi and micro organisms that live on the organic material in the dust fingerprints on the records. 5. Dust is abrasive, and collectively with the pressure exerted on the groove walls by the stylus, can permanently scratch the walls making it worse and unplayable, dust is a great danger to the vinyl reproductive status and can become everlastingly imbedded into the thermoplastic platter. 6. Only a small point of the stylus is actually making contact with the groove walls; one and a half grams of stylus pressure on such a minute surface can be transformed into several tons of weight per square inch. Resulting drag of the stylus generates enough heat to cause the plastic partly melts though not enough to deform. But causing microscopic flow around the stylus and dust to be everlastingly embedded. |
