Yes, I do have GT85, but it's not my door that's squeaking! I have just about every type of spray or bottle liquid they sell. A mate of mine was a fireman, he reckoned my house would be an inferno in 3 minutes with the amount of paint/solvents/etc. I have in my basement.
GT85 is a PTFE-based spray. Surely you have a can of that somewhere?
Also, the kitchen will have 'clean bike' smell. Win!
