I'm not that familiar with that wafer.......is the bandage part (outer part) a cloth material that's perforated (that's what it looks like in the pics), or is it a solid piece of plastic? Also, are you having trouble with the adhesive under the outer section, the inner section or both?
A couple thoughts for you........if you have sensitive or damaged skin under your wafer, then frequent changes will irritate the skin more, as folks have said. If you just don't get much more time out of a wafer (and need to change it frequently) then extending your wear time won't make sense.....but if you can, then try it.
If you're going to experiment with different adhesive removers.....do it on better skin. What I mean is take one of your new wafers and cut it into quarters. Then stick a quarter to your midsection on the side opposite your stoma and leave it there for the 2 days or so until you need to change your real wafer. Then try the new adhesive remover on that quarter wafer first. If it works then you can try it on your good wafer for that change. This prevents you from exposing your sensitive or damaged skin to a bunch of new chemicals it may or may not like.
A couple thoughts on adhesion........adhesive remover takes time to break down the adhesive it's using. If it didn't it would probably be too strong for your skin. So you need to apply it and then give it time to do its thing. If the wafer material is a solid plastic, like my Sensura Mio Convex......the remover won't be able to penetrate the plastic no matter how long you leave it on. It has to 'seep' into the sides of the plastic from the edges. This can be a slow tedious process if you want to avoid skin damage. But if you watch a wound nurse apply adhesive remover she holds the pad or swab against the area that she's removing and doesn't wipe and remove.....she just keeps it in contact with the newly exposed skin as she removes the bandage. This is to allow the remover to seep in from the front edge as she pulls the bandage up and off. The slower you go the less it hurts, as this gives the remover more time to seep in and dissolve the adhesive. A way to speed this up is to take your new wafer, before you install it, and punch a number of small holes in it, say with a paper hole punch. This way when you wipe the adhesive on it seeps in under the wafer from more points, rather than just the edges, and as you're removing in one area the other areas are dissolving. The other way to lessen adhesion overall is to use more stoma powder under your wafer. Obvious the more you use the less adhesion you'll get, so you'd need to play with it a bit. But just apply and blow off with a hair dryer or whatever you use.....and then DO NOT hit it with a skin protectant wipe.....just leave it as be and apply your wafer. Don't cake it on or nothing will stick, but a light dusting and blow off will leave just a trace on your skin that will reduce adhesion a small amount. Less is more here, so you might want to practice this on one of those quarter wafer pieces you've stuck to the other side of your navel. You're going to need to experiment with stuff to figure out what works best for you, and you really don't want to do it on the important skin, and chance messing that up more. See if any of that makes sense and works for you. If not, we'll keep throwing ideas up on the wall and see what sticks!!
