How Do You Unstick a Glue Bottle Cap?
Q. How do I loosen a stuck cap on a glue bottle?
San Jose, California
A. Try hot water or nail-polish remover. That’s right―leave your teeth out of it. Instead, submerge the glue bottle in a glass of hot water for a few seconds. If that doesn’t work, use acetone nail-polish remover (which works best for superglue), says Lori Crowe, a spokesperson for the Adhesive and Sealant Council, in Bethesda, Maryland. To apply, dip a cotton swab in the nail-polish remover and rub it generously around the tip of the bottle and under the cap. Some remover might seep into the glue tip, so squeeze out a couple of drops of glue before you apply it.
To prevent a cap from getting stuck in the first place, hold the bottle upright for several seconds after using it so that the glue drains out of the dispensing tip. Then wipe the tip with an all-purpose cleaner before replacing the cap. Store the glue upright to avoid future sticky situations. ―Danielle Armstrong
