Here Is What I Did.
You are not going to damage a stylus playing a scratchy record. So, wipe that off your worry list. As far as cleaning records is concerned, I aquired some very filthy records some time ago. I just used cold water and some dishwashing liquid, cleaned them with a flannel cloth,and let them air dry. They were quite listenable after that. Yes I know, it's not the audiophile way. But, it worked great for me.
