      The white gunky substances seen on the plastic keys of old, unmaintained typewriters generally isn't mold, but plasticizers coming out of the plastic. These can usually be cleaned off using simple household cleaning products or if necessary heavier cleaners (Goo Gone, alcohol, naptha, etc. - test these on hidden parts first to ensure they don't react with or destroy the plastic or remove the paint of the key letters) followed up by light waxes or polishes and buffing.

    2. Here it’s outside being cleaned with Mineral Spirits, and carb and choke cleaner. I took one trip to the eye doctor when the carb and choke cleaner bounced and sprayed into both my eyes. I was fine, but wear eye protection.
    3. The feed rollers and platen were also a mess. I cleaned them with Bar Keepers Friend and water. Soft scrub also works.

      Cleans them but probably doesn't repair them.
