What can you use instead of 10W-40 to help door hinges from squeaking?

do you mean WD40? You can try Vaseline or cooking oil if you don't want to buy anything special.

A dry lubricant spray works well, is inexpensive and is non-messy. https://www.homedepot.com/p/Prime-Line-9-oz-Dry-Film-Spray-Lubricant-RZ-50-4A24/100559191

Cooking oil is plant based and can spoil then you have a smell, better to use Vaseline.

I use silicone spray.

Mayonnaise - Olive oil? Hand cream.........

Mayo, any oil, oily salad dressings in a pinch-sparingly.

Anything that has a slight oil base in it. Even cooking oil...apply sparingly and open & close the door so the product gets into the hinges.

OMG, these answers are INSANE. Oils go rancid.

Remove the hinge pins ONE AT A Time and clean them

well with some Wet And Dry. Brush on a light coat of

white lithium grease (very inexpensive) a small tube will

last you forever.

Re-install the pin and go to the next ones.

I have used this for over 3,000 doors in High Rise Commercial

buildings, they get 20 times more use in 1 day.

Stay away from WD-40, it is a good product but everyone

thinks it is a Lubricant, WRONG it is a CLEANER

I agree with Lori. A lot of dumb suggestions. Any oily product will attract dirt. WD40 works great but is a lubricant and doesn't stop squeaks. Use withe silicone spray lube. Leaves a coating on the hinges. Lithium grease will also do the job.
