Bros, give you all a hassle free method... apply Vaseline onto it. $2.35 bottle from Guardian/ NTUC... and don't kiasu on the amount applied. Just scoop one big glug of it and apply it generously all over the hinge... redo this method whenever you feel you have wet the hinge and reapply.. very clean very hassle free... plus moisturize your fingers too
I can try shoot a picture of my hinges tonight... minimal rusting... rusting was due to previous accidents of failed pipes etc... and my cabinet has been with me >1 year...
