Public Service Announcement: Here’s your gentle maintenance reminder to clean the slugs on your typewriter to keep your type fresh and crisp.

A gray Royal KMG typewriter on a felt mat sits on a table next to some index cards on one side and a purple bottle of nail polish remover (acetone), a brass bristle brush, and a toothbrush sitting on a blue-ink-stained paper towel on the other. A careful observer might see a black pin with a white moustache stuck to the front of the typewriter underneath the Royal badge.

  1. I don’t do enough typing on a particular machine to warrant a type slug clean, but every time I get a new machine, I do clean the type, and it always makes a world of difference.

    The last slugs I cleaned were on a 1955 Imperial Model T, and the easiest way is with a piece of mounting putty, called Blue tack, but soon to be rebranded Black tack because of all the ink mixed in.

    But that also reminds me that I should be doing it on the 4 loan machines I picked up for my next type in!

  2. Just today. I’m planning to give an Olympia SM2 with a freshly resurfaced platen, new rubber bushings, a fresh ribbon, a non-slip mat, and a felt mat to a close friend as a gift. The young lady was so happy to try a typewriter that I couldn’t resist. It’s her birthday and Christmas gift for the last years. The cleaning of the slugs was the last bit I could do for that machine. I hope it will see a bright future.

  3. Once. My cleaning technique once a machine is put back into service is to…

    1) Replace in cupboard after use

    2) Delay changing the ribbon until it’s all but impossible to read what has being typed. (To be honest I don’t know if this does any harm though it’s also great exercise for the fingers).
