Hi,Thank you for using Just Answer my name is ***** ***** I will help with your question. Is the mechanism clean or is it very dusty? I would suggest cleaning the mechanism with compressed air it is available in a can and then I would clean it with some IPA alcohol, when that is done I would lubricate it with some white lithium grease on the metal moving parts.I hope this helps
I would not use a spray as it will go everywhere I would use a tube and a cotton wool bud and sparingly put it where needed.You could use a silicone grease, I just use a standard cheap white grease, I have been told before that Lubriplate 105 is good for tape mechs I have never used it myself. Cleaning the old grease and dust away should help lots.
