My problem is that it dries out quickly and smells strong

I bought this wart remover for 13 CAD (10 ml bottle). I have tried similar products before, and they work wonders. This product does too, but my concern is that it reeks while you apply it. Another issue is that it dries out a couple of weeks after you open the bottle no matter how tight you close the lid. Yes, I've got rid of some of my wards and calluses, but I wish I could use it for a longer period. I would buy the same brand for sure, but in a different format.
