Help me to lube up


I am using an older HeadRoom Cosmic Headphone amp. I have to switch between 3 different systems quite frequently,

Unfortunately, the jacks are recessed inside of the back-plate, which can make unplugging the RCA's difficult [my fat fingers make grasping the next to one another RCA's a problem]

Can anyone suggest a CHEAP lubricant, which may facilitate removal? But I do not want to degrade the connection.

And any puns are more than welcome :-)
