How to Clean a Vintage Typewriter Safely

A dusty typewriter from an attic or estate sale can look rough and still clean up beautifully. It can also be ruined in an afternoon by the wrong spray, the wrong rag or too much enthusiasm.

This guide is deliberately conservative. It covers what a careful owner can do at home, in the order that does the least harm, and it is clear about where home cleaning should stop and a typewriter technician should take over. If you are not sure whether to restore at all, read restore or leave original? first.

Before you start: photograph and assess

Take photos from every side before you clean anything, including close-ups of decals, the serial number area and any dealer stickers. Old decals and paper labels can be fragile, and once they lift they rarely go back. Our guide to photographing a typewriter covers good angles. Dealer decals in particular are worth preserving; see what dealer decals can tell you.

Then look for anything you should not clean around casually: flaking paint, crazed finish, paper labels, glass-topped keys with paper legends, and decals with lifting edges. Plan to work around those areas, not over them.

Finally, work somewhere with good light, a towel underneath the machine, and a tray for anything that falls off. Small screws and springs love to disappear into carpet.

What you need (and what to avoid)

A soft brush set and microfiber cloths cover most of the job. Browse soft detail brushes and microfiber cloths on Amazon.

Step-by-step: from gentle to thorough

1. Remove the ribbon and spools. Note which way the ribbon threads through the vibrator before removing it, or photograph it. Set the spools aside.
2. Dry dust everything. Use a soft brush to loosen dust and a hand blower to move it out. Work from the top down so debris falls away from parts you have already done. Tilt the machine gently on its back on a towel to brush out the basket and the underside.
3. Clean loose debris from the basket. Erasure crumbs, paper bits, pins and hair gather under the typebars. Pick them out with tweezers or a wooden pick rather than pushing them deeper.
4. Clean the type slugs. See the section below.
5. Wipe the body. Use a cloth barely dampened with mild soapy water, wrung out until it is almost dry. Test on the underside or rear first. Dry immediately with a clean cloth.
6. Clean the keytops. Different keytops need different handling; see below.
7. Clean the platen surface. A cloth slightly dampened with water removes surface ink and grime. Do not soak it.
8. Stop and type. Re-install the ribbon and test. Many machines feel noticeably better after a dry clean alone.

Cleaning the type slugs

Ink and fiber pack into letters like e, a and o over time and make the print look blotchy. The type slugs are metal and tolerate cleaning better than any other part of the machine, but they sit on typebars that do not want to be bent.

• Stiff brush: hold each typebar gently and brush the slug with a stiff toothbrush. Support the bar; do not lever against it.
• Putty-type cleaner: press a small piece onto each slug and lift away. It pulls ink out of the counters without liquid.
• Light solvent on a brush: some owners use a small amount of a solvent on a brush for stubborn slugs. If you do, keep it to the slug face, use very little, and keep it away from paint, rubber and the segment.

Check the result by typing a line of eaoeaoeao. Clean slugs give open, crisp counters. Our post on inspecting key slugs explains what to look for in unusual characters.

For slug cleaning, search for type cleaning putty on Amazon.

Keytops: glass, plastic and chrome rings

Older machines often have keytops with a paper or printed legend under a clear glass or plastic cap, held by a metal ring. Newer machines usually have solid molded plastic keytops.

Yellowed plastic keys are common. Some hobbyists try to whiten them, but methods vary and can damage legends. For a collectible machine, accept honest aging.

Paint, crinkle finish and decals

Paint is where most cleaning damage happens. Many vintage typewriters have glossy paint, crinkle or wrinkle finishes, or colored enamels that look tough but react to the wrong chemical.

• Glossy paint: barely damp cloth with mild soap, then dry. If you want a little shine afterward, test any wax or polish on a hidden area first, and use very little.
• Crinkle finish: dirt sits in the texture. A soft toothbrush with slightly soapy water, used lightly, lifts it. Dry promptly with a soft brush and cloth.
• Decals and gold lettering: do not rub them. Clean around them with a dry swab. Alcohol and solvents can lift decal ink.
• Original color machines: if the color matters to the value, be extra cautious; see our guide to original paint.

The mechanism: where home cleaning should stop

If keys are sluggish, typebars slow to return, or the escapement skips, the cause is usually old, thickened lubricant and dirt in the segment and moving parts. Technicians often address this by degreasing the mechanism with an appropriate solvent, sometimes with the body shell removed, and then letting it dry fully.

This can work very well, but it carries risks: solvent running onto paint or rubber, flammable fumes, and reassembly mistakes. If you want to learn, practice on an inexpensive, common machine first, work outdoors or with strong ventilation, keep solvents off painted and rubber parts, and follow the solvent maker's safety directions exactly. For a valuable machine, a technician is the right call.

Cases and covers

Cases often smell worse than they look. Vacuum the lining gently, air the case in shade (not direct sun, which fades and dries materials), and let it stand open for a few days. Our guides to removing odor from a typewriter case and case smell: cleaning versus damage go deeper.

Mistakes to avoid

• Spraying anything directly onto or into the machine
• Using WD-40 or household multi-purpose oil inside the mechanism
• Soaking the platen or feed rollers in any liquid
• Rubbing decals, labels or gold lettering
• Bending a typebar while scrubbing its slug
• Removing screws without photographing their positions
• Drying the machine with heat; let it air dry at room temperature
• Oiling to "fix" sticky keys (it usually makes them worse)

Next steps

Once the machine is clean, a fresh ribbon makes the biggest visible difference. Shop typewriter ribbons on eBay If the clean revealed a fault you want to fix with a part, searching by model plus the part name works best: typewriter parts on eBay.

If you are curious how cleaned and serviced machines are presented, compare sold "cleaned and serviced" listings with similar unserviced ones, and read the listing descriptions closely. The most useful ones say exactly what was done.
