So far, all the above replies appear to be sound advice, so I won't repeat what they have already said. But, of course, you 'could' use whatever you want to, but some methods are 'wiser' than others.
However, you ask a perfectly relevant question which deserves a little more exploration like:
What is motivating you to think about doing such a thing? Is it to remove dirt or adhesive? or is it to take away a blemish on the skin? or some other reason?
I have found that removing dirt and/or adhesive is best done with adhesive remover, either in the spray or wipe versions. Also, I have a plastic 'cup' (which has a diameter about the same size as the diameter of the wafer) that was provided by one of the manufacturers, which can be half filled with plain warm water and put over the stoma area and be shaken well to wash it for a few minutes every day to keep it clean. I then remove the cup and gently wipe the area with a dry wipe. This 'special' cup is almost exactly the same as the plastic containers that my prawns come in, so I have kept one of these back in case the original gets damaged.
I hope you find something appropriate to resolve whatever problems you are facing in this regard.
