Removing adhesive from bathing suit liner?

I was going to suggest turpentine, but it looks like rubbing alcohol is a better bet.

Alcohol is sold in many forms: isopropyl, methyl, wood, ethyl and denatured alcohol. Isopropyl alcohol is the familiar rubbing alcohol and is formulated for external medicinal use. It is also useful for removing resinous stains on clothing and for removing the gummy tar residue on ashtrays.

Try soaking the area with a few dollops of gel soap/detergent and leaving it to sit for about an hour. Take a smooth spoon edge and lightly scrape along the fabric to see if you can lift the gummy residue and soap gel together. Sometimes lotion works to make glue stuff lift and roll into little balls to wash away.

I use denatured alcohol at work for removing all sorts of resins I get on my nice clothes. I have never had it stain and does a great job.

Outside if the denatured alcohol have you tried a hand-held steamer? You might be able to get it to loosen its hold enough to roll it off. If you test to make sure it won’t stain you can soak it a few minutes in lemon oil rub off the gunk then launder the suit.

If you use the lemon oil, be sure to wash it by hand, then line dry. Lemon oil is flammable, as I recall, so don’t put the suit in the dryer.

I would return it.

Having had this problem, I used white vinegar on some kitchen roll and rub gently but firmly, the sticky stuff rolls and removes…brilliant!
