The first step is to assess the extent of the damage and determine if removal is even possible without damaging the card. Carefully examine how strongly the card is adhered to the paper. If the glue is very thick or the card is extremely fragile, removal may not be advisable. If the glue appears thin and the card is in decent condition, removal can be attempted.
One method that may work is by carefully warming the glue to soften it without applying direct heat to the card. You can use a hair dryer on its lowest heat setting held 6-10 inches away from the card/paper. Slowly move the dryer back and forth over the glue while also applying gentle upward pressure with your other hand on the card. The goal is to soften the glue enough that it can be teased off the paper without tearing the card. Be patient, as this may take several minutes. Check periodically if the card can be safely separated.
If warming the glue doesn’t work or isn’t advisable due to the card’s thinness, the next step is using mineral or gum spirits to dissolve the adhesive. Place a small amount of the solvent onto a cotton ball or swab and dab it gently onto the glue, focusing only on the area between the card and paper. Wait 30-60 seconds, then try carefully lifting the card edge. Re-apply solvent as needed while still being careful not to get any on the card surface itself. The goal is to dissolve the glue bonds without damaging the card.
You may also try using plastic scrapers, dull craft/hobby knives, or bamboo skewers to gently peel up the glue from the card surface. Hold the tool at a low angle and slide it underneath a corner or edge of the card. Pry or twist very carefully to separate the glue seal. Go slow and be patient, taking breaks if you feel you are applying too much pressure. The goal is a gradual, delicate loosening rather than forcing or tearing the materials apart.
Another option if the above methods don’t work is to use a solvent designed specifically for adhesive removal like Goo Gone. Apply it with a cotton swab, wait the recommended time, then try gently lifting edges as described. Test the solvent on a small inconspicuous area first to check for damage to the card surface. Some solvents are known to discolor or interact badly with the materials cards are printed on, so proceed with caution.
No matter which method you use, have a clean work surface and take breaks if you start to feel frustrated. Use soft natural light, not direct sunlight which can damage the cards over time. Lift from edges, not middle of card. Go very slowly – it can take 10 minutes or more of tedious work to remove each one properly without tearing. Patience is key to a successful removal without harming the cards. With care and by taking your time, it is often possible to preserve the cards intact. But assess condition first and don’t force removal if too risky to the particular card. With the right supplies and techniques, you can carefully lift cards glued to paper.
