There is something called adhesive remover. Usually it's used as a stoma adhesive remover. It may be known as an adhesive wipe...I'd have to look and see if I have some. Comes in a box with bunches of little packages. It works fairly well. There is also a product that primes the skin so that adhesives will stick better. That product I would suggest speaking with a pharmacist about though to make sure it doesn't interfere. The adhesive remover is great though. Fingernail polish, if I remember correctly works in a pinch although I find it to be a bit harsh.
