I've used, WD-40, and household oil but it never seems to last. Any recommendations on the best stuff to keep those hinges lubed?
WD-40 will evaporate .... i like to get a shot syringe used for pets ...and fill it with white lithium grease ... you can really pinpoint here it goes. it takes some practice, and buyin a few different needle sizes till you get it right ... but once you do, it works great. store it way out of reach of kids.
