WD40 safe on door hinges?
My driver's side door has developed a squeak now. Want to know if WD40 is a safe solution and if so, where exactly to spray on the hinges or if I need to use something else. Thanks

You shouldn't "hurt" anything (see how many times it's used to clean tar, etc.) but it probably won't last long.
Buy a spray can of grease (I forget the name - NAPA can tell you!) and use the WD40 to clean the area after you've treated the doors!

Gotcha. I just remember using it on my room door when it creaked and it went away immediately and effortlessly. Not sure where I can get this, any particular kind better or worse?

I just wasn't sure if there were any plastic parts or anything to shy away from in the hinge structure. Didn't want to break something while trying to fix something LMAO.

I personally like Breakfree CLP or Tri-Flow with teflon for lubrication on metal parts. For extreme use in dusty/dirty environments, my favorite it Militec-1 synthetic but it works best when heated to above normal temperatures to bond to the metal surface. Big advantage is it's a "dry" lubricant.
WD-40 will eliminate a squeak for a short while but so will water... or fish oil.
There are uses for WD-40, my favorite... removing store stickers. It'll remove gum from hair too.

Fact:
Consumers have told us over the years that they have caught some of the biggest fish ever after protecting their fish hooks and lures with WD-40. We believe this legend came from folks assuming that the product must contain fish oil since it appears to attract fish. Sorry Charlie®, it just ain’t so.

Fish oil is the main product in Rustoleum paint and is the reason it takes so long for the paint to dry...maybe someone got the two mixed up?

Use white lithium grease, i sprayed it on my driver's side door hinges almost 2 years ago, and zero squeaks!
Water resistant too. =)
WD-40 will only cure the problem temporarily, it's not really a lubricant, but it's designed to repel water and prevent corrosion.
I would recommend using WD-40 to clean the hinges real good, wipe off, then apply some white lithium grease (comes in a spray too, available at your local auto parts store). Wipe off any excess grease. (Open and close the door repeatedly so the grease spreads around the hinges).
I did this almost 2 years ago, and i'm telling you, the squeaks never came back!
You will love it.
