I am surprised you don't use the tried & tested method of spreading a thin layer of PVA (artists or decorators works best ).on to the record up to the beginning of the run out grooves . waiting for it to dry completely the peel of like a face mask no water no chemical just plain cheap PVA go to utube for film of method .
I do that once when I buy them if they are pre owned . really cheap 100% clean no damage from minerals. enjoy the sun sounds & sunday
