Hi Doug
I don't clean. I get the feeling they may be talking
about silicone glue and not the grease. The oil is about
as non-corrosive as anything that I've seen.
On my boat, I use it on light sockets and any connections
I make. The only failures I've had are the original connections
made by the manufacture and previous owner. You do want to
apply it to a clean surface. Any salt covered over will still
be salt. Anyway, it make me wonder.
Well, they did say "under the right conditions", what they didn't
say is that those conditions are (maybe) only found in a lab...
;-)
