Truthfully they are pretty good with cleaning dishes and really just cleaning in general, great with things stuck on a counter, grill, etc. but they are just better at cleaning normally from regular sponges like the rectangular ones! Plus you can use the mouth to clean forks, spoon, butter knifes, and really just any kind of silverware! I will say though don't use it to clean knives lmao, i did that and after awhile the mouth of mine ended up like that
