    I need to clean and lubricate a LaGard type safe lock. The lock always opens, but the dial is getting just hard enough to turn so that it makes it difficult to land right on the combination value.

    Are there certain lubricants that should (or should not) be used?

    Are there components that should not be lubricated?
