|You probably don't want to stop the oozing. Keep it under control with the calamine or other type products.
(After a shower, I would pour witch hazel over the area then apply a concoction of 1/3maalox, 1/3peroxide and 1/3 listerine type products. Mix it up and dab it on. Keep the extra mixture in the fridge. It feels so much better when it's cool and applied to the rash. It well help clog it up but not entirely. It will also help prevent infection.)
