I like the smell of liquid Arm & Hammer HE, so I add just a small amount in the bottom of the cap to loads I wash in powder Tide HE. I guess I should see if it can kill the evil odor of liquid Tide HE if I combine the two. Powder Surf has vanished from stores in my area. While I guess most of you would dislike it for its strong fragrance, I like it. If it still exists, they probably have changed it by now and ruined the fragrance, so maybe it's no great loss.
