I've read this is good maintenance for your turntables every 'X' amount of hours of use and I've never done it. Now I remember when I first got my turntables and I had to assemble the platter, I just dropped it right on. Now I can't get it off to apply any lubricant. What's the trick to getting the platter off of a SL-1210 Technics turntable. Also, Any thoughts on applying this oil? How to? Should I? Etc.
