I had an Ideal Garage master cylinder and ended up going back to OEM because it was leaking internally. All the clutch issues I've had on both cars in relation to pedal not coming back were fixed with remote reservoirs and extended bleeder lines.

Lubricant won't hurt anything up there, but it will make it collect dirt so you or the next owner get to deal with that next time you're upside down trying to work under the dash. When I need to put lubricant in a tight spot, I use glue brushes. I just bought 50 for like $10. Not always the solution, but if it will do the job, it's much cleaner than spraying white lithium everywhere.
