A trace of silicon. Use an automotive tire shine that does not contain "petroleum distillates".
Find a clean non-shedding soft rag (new diaper) and put the fluid on the rag until it is damp. set it aside untill it is dry. The just wipe the LP surfaces lightly with the dry rag (full of silicon). You only have to get a TRACE on the flats next to the grooves, not into the grooves.
The records will remain static free for a very long time.
