3 in 1 Oil For Shower Door Hinge

[George7941]

Instructions call for using 3-in-1 oil for lubricating the hinges. Plastic washers are used in the hinges and, as far as I can make out, 3-in-1 mineral oil is safe for plastic whereas spray on white grease could attack plastic

Mineral oil is derived from petroleum and is safe for plastics whereas grease, also derived from petroleum, isn't?

How about SHC oils, like PAO Mobil oils, for plastic?

Here's Super Lube's compatibility chart for you to get an idea how their Super Lube oil and Super Lube silicone do with various plastics and rubber:

I'd go with a penetrating oil containing graphite. Wipe off the excess that will seep out, and the remaining graphite will lubricate and not care about moisture. If you can get dry graphite in there, also good.
