I keep a bottle of cheap shampoo for just this job and it works every time, so I guess it is that or the dawn. Good luck, popet
Best thing I've found is Dawn dish detergent. Wet the collar then put a little of the Dawn on the ring, give it a good scrub before you put it in the washer. I'd think any type dish detergent would probably work too but I always use Dawn; seems to go farther.
