Hi,
Deoxit by Caig Labs replaces the Cramolin product.

The D5 is a 5 % concentration and normally cleans up most dirty contacts and
surfaces.
Very little is needed.

One contact cleaner that I used that was better than most was
Cramolin. This is a monomolecular layer solution that you would use
very sparingly. However, as your tuner did not arrive brand-new (or
brand-used) with it, your problem may be more mundane.
The simplest way to defeat corrosion is with pressure. The spring
tension of the roller may have slackened up over the years.
