@desertskybulldogs said she was using malacetic utra like 2 days a week on tear stain and it was helping. I bought this stuff also and in the wipes....I didn't wanter mine down but I used it on an infection in a face fold and it cleared p by the next day! That stff really works! I would say for the ears I wold put it on a cotton bal or Q Tip....It is strong smelling...I sed the wipes on Coops face last night and then afterwards is when he threw p so I was concerned it was from the smell but since he did it agaoin tonight I am not so sure. I clean is face with water and some soad and he doesn't mind but he fought me and hated the malactic on his face!! Good luck!!!
