Anyway, I stink!

I got a bit lazy and started using spray deodorant that was so convenient when I needed it, and since then my armpits started to smell bad very quickly. So I stopped using it and there was a great improvement. I made some home-made deodorant following instructions in a book, I think it was cornflour, bicarb and a herb - I chose lemon thyme. That helps with the smell when I need it, but I'm really just trying to keep the pits clean and not in need of any 'help'. However, there is one part at the top of my right armpit that I can't stop smelling!

Any suggestions before I become lonely?
