To clean a leather journal cover, dust it with a dry soft cloth, lift marks with a barely damp cloth or a white vinyl eraser tested on a hidden spot, let it air-dry, and condition only when it feels dry. For ink, blot at once, match the method to the ink type, and stop before you strip the finish.
Key Takeaways
- Start dry, then go gentle: soft cloth first, barely damp cloth or a white vinyl eraser second, solvents only as a last resort on a tested spot.
- Know your ink. Fountain pen ink is usually water-based and lifts best while fresh; ballpoint ink is an oil-based paste that resists water once dry.
- Match the routine to the material: smooth cowhide, waxed crazy horse and PU each need slightly different care.
- Never use bleach, hydrogen peroxide, acetone or saddle soap on a dyed or waxed journal cover.
- Condition by feel, not by calendar, and store leather at ordinary room humidity away from heat and direct sun.
The basic cleaning routine for any leather cover
The basic routine is four steps: dust, spot-clean, dry, and condition if needed. It works for cowhide journals, refillable covers and pen cases, and it is gentle enough to repeat whenever a cover looks dull or grubby. Always test anything wet on a hidden spot first.
- Dust. Wipe the whole cover with a dry, soft cotton or microfiber cloth. Brush dust out of stitching with a soft brush.
- Spot-clean. For grubby marks on smooth leather, conservators suggest white vinyl or powdered erasers, used only after a small test on an inconspicuous area, and not on suede (Canadian Conservation Institute, CCI Notes 8/2). For sticky marks, use a cloth dampened with plain water and wrung out until it is barely moist.
- Dry naturally. Let the cover dry at room temperature, open and standing, so both sides breathe. Do not use a hair dryer or radiator; local heat speeds drying and breakdown of leather (CCI Notes 8/2).
- Condition if it feels dry. Apply a thin layer of leather conditioner with a soft cloth, wait for it to absorb, then buff. Skip this step on PU.
Cleaning routines by material
Smooth cowhide, waxed crazy horse leather and PU look similar on a shelf but behave differently when you clean them. Cowhide tolerates a barely damp cloth and occasional conditioner, crazy horse prefers rubbing and buffing to washing, and PU only needs a damp wipe because nothing soaks in.
| Material | Everyday care | Spot cleaning | Conditioning | Avoid |
|---|---|---|---|---|
| Smooth cowhide (for example our Thick Cowhide Leather Journal) | Dry cloth, clean hands | White vinyl eraser or barely damp cloth, tested first | Thin coat when it feels dry or stiff | Soaking, heat, heavy oil |
| Crazy horse or other waxed, oiled finish (for example our Crazy Horse Refillable Journal Cover) | Rub marks with a fingertip, buff with a dry cloth | Blot spills, let dry, then buff to blend | Small amount of a cream or balm for oiled or waxed leather, only when pale and dry | Saddle soap, straight oils, harsh solvents |
| PU / faux leather (for example our A5 Faux Leather Notebook) | Damp cloth wipe | Damp cloth with a drop of mild soap, then a clean damp cloth | Not needed; oil just sits on the surface | Solvents, abrasive sponges, heat |

How to remove ink stains from leather
To remove ink from leather, blot fresh ink immediately without rubbing, identify the ink type, and use the gentlest method that works: water for fresh fountain pen ink, an eraser and then a carefully tested touch of alcohol for ballpoint. Older, set stains on porous leather often cannot be removed fully.
The ink type matters because the two common pen inks are chemically different. Fountain pen ink is a water-based liquid, and standard fountain pen inks are mostly dye-based (Wikipedia: Fountain pen ink). Ballpoint ink is a paste containing around 25 to 40 percent dye suspended in solvents such as benzyl alcohol or phenoxyethanol and fatty acids, which is why it is called oil-based; once dry it resists water, but alcohols and acetone can dissolve it (Wikipedia: Ballpoint pen).
| Situation | First try | If it is still there | When to stop |
|---|---|---|---|
| Fresh fountain pen ink (water-based) | Blot with a dry paper towel, then dab with a barely damp cloth | Repeat blotting with a clean damp area of the cloth; let dry and reassess | When the cloth stops picking up color |
| Set fountain pen ink | Barely damp cloth, dabbing only | On smooth sealed leather, a white vinyl eraser after a test | If the ink has soaked into an unsealed or waxed surface |
| Iron gall fountain pen ink | Blot immediately | Usually little; it is formulated for permanence | Early; accept a faint mark |
| Fresh ballpoint line | White vinyl eraser, tested first | Cotton swab barely moistened with isopropyl alcohol, on a tested spot | If color from the leather appears on the swab |
| Set ballpoint on smooth cowhide or PU | White vinyl eraser | Alcohol swab, one light dab at a time, then dry | After a few light passes |
| Any ink on crazy horse or another waxed finish | Blot, let dry, buff | Rub with a fingertip to blend into the wax | Before using any solvent; let it become patina |
Iron gall ink is still used for applications that require permanence (Wikipedia: Fountain pen ink), so do not expect it to lift the way a standard dye ink can.
Step by step: fresh fountain pen ink
- Blot straight away with a dry paper towel. Press and lift; do not rub, which spreads ink into the grain.
- Dampen a clean cloth with plain water and wring it out until barely moist.
- Dab from the edge of the stain toward the center, turning to a clean area of the cloth each time.
- Let the cover dry at room temperature and look again in daylight.
- If the leather feels dry where you worked, apply a thin layer of conditioner over the whole panel so the color stays even.
Step by step: ballpoint pen marks
- Try a clean white vinyl eraser first, on a hidden spot and then lightly on the line.
- If the line remains, moisten a cotton swab with isopropyl alcohol and squeeze it almost dry.
- Test the swab on a hidden area. If any leather color comes off, stop: alcohol can lift the finish as well as the ink.
- Dab the line, do not scrub, and switch to a fresh swab as soon as it picks up ink.
- Wipe the area with a barely damp cloth, let it dry, and condition real leather lightly afterward. On PU, a damp wipe is enough.
When to stop and accept patina
Stop when the cleaning starts to change the leather more than the ink does: lighter patches, a dull spot, or color on your swab. On waxed, oiled and darker leathers, a faint ink mark often becomes less noticeable as the patina develops, and it is far less obvious than a bleached or stripped patch. Our guide to leather patina explains why marks soften over time.
What never to use on a leather journal cover
Do not use bleach or hydrogen peroxide, acetone or nail polish remover, saddle soap, household sprays, baby wipes, abrasive melamine sponges or heat on a dyed or waxed journal cover. Each can remove color, strip the finish, leave residue or dry the leather out faster than any ink stain would harm it.
- Hydrogen peroxide and bleach. Hydrogen peroxide is an oxidizing agent, best known as a bleach; consumer bottles are usually 3% to 6% solutions (Wikipedia: Hydrogen peroxide). On dyed leather, a bleach lightens the leather along with the stain.
- Acetone and nail polish remover. They dissolve ballpoint ink, but they are strong solvents that can also dissolve or dull finishes and PU coatings.
- Saddle soap on finished stationery leather. The Canadian Conservation Institute describes it as very alkaline, able to degrade leather and to leave a white, scummy deposit (CCI Notes 8/2).
- Abrasive sponges. Melamine foam works like very fine sandpaper and can remove the surface along with the mark.
- Soaking and heat. Never soak a cover to wash it, and never speed up drying with a hair dryer or radiator; the CCI note warns against local heat. Let a wet cover dry slowly at room temperature.
How often should you condition a leather journal?
Condition a leather journal when it tells you to: when the surface looks pale, feels dry or stiff, or after you have cleaned a stain. For a cover used indoors and handled daily, that is occasional rather than routine, because your hands already add light oils as you use it.
More conditioner is not better. Museum conservators no longer generally recommend leather dressings on collection objects, because applied oils can darken the surface and, as they oxidize, stiffen the leather (CCI Notes 8/2). A journal you carry is not a museum object and does benefit from the occasional thin coat, but the lesson carries over: use a small amount, test it first, and accept that any conditioner deepens the color slightly. PU covers never need conditioner.
Storage and humidity
Store leather covers in ordinary, stable indoor conditions, away from heaters, damp basements, hot cars and direct sun. The Canadian Conservation Institute recommends a stable relative humidity of 45% to 55% and a temperature of 18 to 20°C (about 64 to 68°F) for leather (CCI Notes 8/2).
The same note explains the risks at either end: below 30% relative humidity leather loses moisture and becomes brittle, and above 65% mold and fiber breakdown become more likely. Light damage is cumulative and irreversible. In practice:
- Keep spare covers in a drawer or a breathable cloth bag rather than on a sunny windowsill.
- Do not seal damp leather in plastic. Let it dry first.
- Store pens capped and upright or in a case, so a leaking pen does not ink the cover.
- Keep dark crazy horse covers away from pale fabric or paper while they are new and waxy.
- For refillable TN-style covers, remove soggy inserts after a spill and let the cover dry open. Our traveler's notebook style journal guide covers inserts and setup.

Frequently asked questions
What conditioner to use on crazy horse leather?
Use a small amount of a cream or wax-based balm made for oiled, waxed or pull-up leather. Test it on a hidden spot, apply a thin layer with a soft cloth, let it absorb and buff. Avoid saddle soap and straight oils, which can leave residue or darken the finish unevenly.
What does hydrogen peroxide do to leather?
Hydrogen peroxide is an oxidizing bleach, so on dyed leather it tends to lighten the leather itself along with the stain, leaving a pale patch that is harder to hide than the original mark. It is not a safe ink remover for journal covers.
Can you get ballpoint pen ink out of leather?
Often, if you act early. Try a white vinyl eraser first, then a cotton swab barely moistened with isopropyl alcohol, tested on a hidden spot and used in light dabs. Stop if leather color shows on the swab. Set ink on porous or waxed leather may only fade, not vanish.
How often should you condition a leather journal?
Condition it when it looks pale or feels dry or stiff, and after cleaning a stain, rather than on a fixed schedule. Use a thin coat and buff. Daily handling adds light oils, so a well-used indoor journal needs conditioner only occasionally, and PU covers never need it.
