How to Clean an Electric Typewriter | Safe Steps for Dust-Free Keys

For the full breakdown, see our best Electric Typewriter guide.

An electric typewriter that types cleanly and doesn’t jam is usually one that’s been dusted and wiped down regularly. Knowing how to clean an electric typewriter properly means understanding the difference between dust removal, safe solvent cleaning of metal parts, and gentle exterior wiping — and each matters.

Before You Start: Safety and Workspace Setup

Unplug the typewriter from the wall outlet before touching anything inside. This is not optional — the machine contains live electrical components, and the cleaning process involves reaching into areas near the motor and solenoid assembly.

Cover your work surface with newspaper, old towels, or a rag. Electric typewriters accumulate decades of dust, dried oil, and paper fiber in the carriage area and around the typebars, and that debris will fall out as you work. A protected workspace makes cleanup instant.

Remove the ribbon spools or ribbon cassette if your model allows it. Also open any access panels or removable covers that expose the inner mechanism. Better access means a more thorough clean.

What Tools Do You Need to Clean an Electric Typewriter?

You only need a few items, and most are already in the house or garage. Stick to the list below — substituting the wrong cleaner or tool is the fastest way to damage a typewriter.

Cleaning an Electric Typewriter: Interior and Exterior Step by Step

1. Blow out the loose dust. Use compressed air to clear dust from the keybeds, the carriage area, the typebars, and any visible internal mechanism. Work from the inside out so debris exits rather than settling deeper. Follow up with a brush on stubborn patches, then blow again.

2. Clean the metal moving parts. Dip a brush or a cotton swab in a small amount of mineral spirits or isopropyl alcohol — not so much that it drips. Work the solvent into sticky typebars, the carriage rails, and any pivot points where the action feels sluggish. Typewriter specialists recommend mineral spirits for this job because it evaporates cleanly with little residue. Wipe each treated part dry with a clean cloth and let the mechanism air-dry fully before plugging the machine back in.

3. Wipe the platen and feed rollers. The rubber platen (the roller the paper wraps around) and the small feed rollers pick up ink and dust over time. Rub gently, then wipe dry. Excessive solvent or soaking will harden the rubber.

4. Clean the exterior body. For painted metal or plastic shells, a microfiber cloth with a little mild soap and warm water is safe and effective. Dab the cloth — never the machine — and wipe carefully around decals and key legends. Dry immediately with a second cloth.

FAQs

Can I use WD-40 to clean an electric typewriter?

No. WD-40 is not a cleaner or lubricant for typewriter mechanisms. It leaves a sticky residue that attracts dust and can cause moving parts to seize up over time. Stick to mineral spirits or isopropyl alcohol for metal parts.

How often should I clean an electric typewriter?

Is it safe to vacuum an electric typewriter?

Yes, but use a soft brush attachment and keep the nozzle away from delicate linkages. Vacuuming is effective for loose debris after brushing, but compressed air reaches deeper into the mechanism.
