Souvenir magnets are a construction, and the construction decides how long they last

Resin, cast metal, ceramic and wood age differently on a fridge door. Knowing which one you own tells you how to display it and how to clean it without ruining it.

Construction	Durability	Colour retention	Watch out for
Resin dome over a printed insertWipe. Abrasive cleaning dulls the dome's shine over time.	The dome resists scuffing well, but the resin can yellow or develop fine surface cracks (crazing) after years near a warm hob or in direct sun.	The print stays bright as long as the dome stays clear. Once the dome yellows, the colour underneath dulls with it.	Lifting or cracking at the edge of the dome, which lets moisture reach the print beneath.
Cast metal, painted or enamelledA lacquered finish resists tarnishing better than bare metal.	The metal body is hard-wearing and resists denting. Painted or enamel fill is the part that gives way first.	Enamel colour holds well for years. Painted detail wears thin at raised edges from repeated handling.	Paint chipping off raised design elements, and corrosion on unlacquered metal in a humid kitchen.
CeramicKeep away from the edge of a shelf or door where a knock is more likely.	The glaze is hard and scratch-resistant, but the body is brittle. A drop onto a hard floor is more likely to break a ceramic magnet than any other type here.	Glazed colour does not fade under normal kitchen light, so a ceramic piece can look as bright at ten years as at one.	Chips at the edge and hairline cracks, which weaken the piece and often lead to a full break later.
Wood, printed or engravedKeep wood magnets away from direct heat sources on the fridge or nearby wall.	Engraved detail keeps its shape regardless of wear. Printed detail on wood wears from handling faster than on resin or laminate.	Printed colour on wood fades under sustained sunlight. Engraved wood has no colour to fade, only the wood's own tone, which darkens slightly with age.	Warping near a hob or radiator, since wood moves with heat and humidity in a way the other constructions do not.
Printed laminate on flexible magnetic sheetA lifting corner can sometimes be pressed back down while it is still small; once grease has got underneath, it cannot.	The laminate film protects the print from light scuffing, but it is thin, and the corners can begin to lift after a few years of handling.	Lamination slows fading rather than stopping it. Years of direct sun still dull the printed colours underneath.	Peeling lamination at the corners, which lets grease and moisture reach the print and cause staining.

This is general guidance on how each construction typically behaves. Souvenir magnets are rarely labelled with their construction, so where you cannot tell by looking, ask the seller before assuming durability from the picture.

Displaying and looking after a collection

When the fridge door runs out of space

Once a collection outgrows the door, the practical option is a dedicated magnetic surface elsewhere: a sheet of galvanised steel screwed to a wall, a magnetic whiteboard mounted for the purpose, or a length of steel strip fixed along a shelf edge. Any of these works because the magnet does not care what shape the steel is in, only that it is ferritic steel, the magnetic kind used in most fridge doors and worktops. Magnetic paint, which suspends iron particles in the paint film, is the weakest option and will usually hold a single printed laminate magnet but not a heavier cast metal or resin one. Position the board away from a radiator or a south-facing window, since heat and direct sun affect the collection faster than the fridge door ever does.

Cleaning by material

How a souvenir magnet should be cleaned depends on what it is made of, and treating them all the same way is the most common cause of damage. The construction of the piece, covered in the earlier section on souvenir magnet materials, decides which cleaning method is safe.

Resin magnets have a clear domed coating that scratches easily. A damp cloth is enough; abrasive sponges and kitchen sprays dull the gloss over time.
Ceramic pieces have a fired glaze that tolerates most household cleaners without harm, since the glaze is the same finish used on tiles and crockery.
Cast metal magnets should be wiped dry. Water that gets behind the casting and sits against the magnet or its backing plate can start surface rust.
Wood magnets take a damp cloth at most. Soaking lifts the varnish and can warp a thin wooden blank.
Printed laminate magnets are a paper or card print sealed under a plastic film. Solvent-based cleaners get under the edge of that film and lift it, so a damp cloth is the safer choice here too.

Colour fading from sunlight

Printed inks and coloured resins fade under sustained ultraviolet exposure, which is why a magnet kept on a sunny windowsill loses its colour faster than one on the fridge door itself. A window ledge typically gets several hours of direct sun a day; a fridge door, unless it faces a window, gets very little. There is no published lightfastness standard specific to souvenir fridge magnets, so the practical rule is simply to keep a collection out of direct sun.

Loose magnets and peeling prints

The two failures that turn up most often are a magnet disc that has come away from its backing and a printed laminate whose film has started to lift at the corner. A loose magnet disc can usually be re-glued with a strong general-purpose adhesive rated for metal and plastic; ordinary cyanoacrylate (superglue) will often hold too, but it sets rigid and can fail again once the magnet is repeatedly flexed against a curved fridge door. A lifting laminate is harder to fix properly: once air and moisture get under the film, the print underneath starts to discolour, and resealing the edge only delays the same problem. At that point, it is usually a case of accepting the piece as it is.
