The short answer
Preserving old recipe cards is two jobs. First, photograph every card soon, in good light, and turn the photos into readable text while the handwriting can still be made out. Then store the originals in clear plastic sleeves (polyester, polypropylene or polyethylene, not PVC) inside an acid-free box somewhere cool and dry, and cook from copies instead. Sharing the digital copies with family means the recipes survive even if the box doesn't.
Step-by-step
- 1
Photograph every card before you clean or sort them
Each year of waiting costs a little legibility, and each time you handle a fragile card you risk a tear, so the photo comes first. Lay each card on a plain background near a window with indirect daylight, hold your phone flat above it, and shoot. Get the backs too. A shoebox of cards takes about an afternoon.

Turn the photos into text and decode the shorthand
A photo stops the fading, but barely legible handwriting stays barely legible. Typing it up yourself, or letting an AI tool transcribe it (they read cursive and old handwriting well), gives you a copy you can cook from. It helps to do this while a parent or aunt can still help with a hard word, and with old terms like "oleo," "moderate oven" (350–375°F), "1 box" of a product that no longer exists, or "mix as usual." A short note on the recipe saying what they meant saves the next cook from guessing.

Store the originals in sleeves inside an acid-free box
Slip each card into its own clear sleeve made of polyester (sometimes sold as Mylar), polypropylene or polyethylene. Avoid PVC or vinyl, which gives off chemicals that yellow paper; sleeves marked "archival" or "PAT passed" have been tested for this. Stand the sleeved cards in an acid-free, lignin-free box. The National Archives suggests keeping it below 75°F and below 65% relative humidity, out of damp basements, garages and hot attics, so a closet shelf in the main part of the house usually works. Keep it out of direct light too. Laminating is best avoided: it can't be undone, and heat lamination can darken old paper and trap acids inside.

Cook from a copy and keep the original out of the kitchen
Splatters, flour, wet fingers and steam did most of the damage you're now trying to stop. Bring your phone or a printed copy to the stove and leave the original in its sleeve. If you like the look of a recipe tin on the counter, you can fill it with printed copies and keep the originals in the box.

Share copies with the rest of the family
One shoebox is easy to lose, and so is one phone. Sending the digital collection to siblings and children puts the recipes in several places at once, and keeping them stops being one person's job.
Common mistakes to avoid
- ✕
Holding the stack together with rubber bands or paper clips
Rubber bands dry out, go sticky and fuse to the cards they touch. Ordinary steel paper clips rust and crease the corner they grip. Cards stored loose in a box are safer than cards bundled neatly.
- ✕
Mending tears with tape
Tape yellows and leaves a stain that can't be undone. The Library of Congress advises against any self-stick tape, even tape sold as archival. A polyester sleeve holds the pieces of a torn card together without any adhesive.

Waiting until you can do the whole tin properly
If a free afternoon for the whole box isn't coming soon, photograph the ten cards you'd most hate to lose today, on the kitchen table, in whatever light you have. You can redo them properly later, and the pencil keeps fading in the meantime.
Why Culinary Card works for this
Culinary Card reads a photo of a handwritten card and turns it into a typed recipe, and it can keep the photo on the recipe in 'The Original' section so the handwriting stays next to the readable version. You can then group the recipes into a book and share it with family by link.
Frequently asked questions
What if a card is already too faded to read?
Photograph it anyway, then try raising the contrast in your phone's photo editor; pencil often comes back better than you'd expect. Older relatives may be able to fill the gaps, and cooking it together from memory can rebuild the rest. Part of a recipe is still worth saving.
Do I need a scanner, or is my phone enough?
A phone in indirect daylight is enough for most cards, and it doesn't press a curled or fragile card flat the way a flatbed scanner does. A scanner works fine for cards that lie flat easily. With a phone, turn the flash off and fill the frame with the card.
How should I handle very fragile cards?
As little as possible, with clean, dry hands, supported flat on a clean surface. Photograph them exactly as they are. If a card is crumbling or has mold on it, a paper conservator can help, but take the photo first.
What about grease stains? Can I clean them off?
It's safer to leave them. Grease, butter and vanilla stains are set into the paper fibers, and rubbing or using solvents at home does more damage than the stain does. Many families like them anyway, since the splatters show which recipes got cooked most. A sleeve keeps the stain from spreading to the cards next to it.
Is it worth preserving cards for recipes nobody cooks anymore?
That's up to you, and plenty of families keep them. The molded salad from 1962 may never be dinner again, but the handwriting, the brand names and the margin notes still record a person and a time.
Does a digital copy keep the actual handwriting, or just the text?
A transcription keeps only the words. If you keep the photo alongside the text, in the same note or folder or on the recipe in whatever app you use, you have both: the handwriting and margin notes, and a version you can read at the stove.
Should I laminate a printed copy for the kitchen?
That's fine. A printed copy can be replaced, so seal it however you like. The advice against laminating is only about the original card.
