Hi all, bought some lithium grease to oil windows doors locks wipers aerial etc. I heard its the best and was expensive. Although it worked great at first, everything now is not so smooth just a month in. Touching the overspray it seems to have congealed to a thick paste. Never had this problem with silicone. So have i misread that lithium grease is a suitable alternative. I think ill just get silicone anyway and redo as its not worth a broken wiper mechanism but interested to know what lithium grease should and shouldnt be used for?
