Has anyone tried oral rinses for cats' teeth?

The Vet's office was selling a bottle of liquid drops that can be added to kitty's water to help clean their teeth. Has anyone tried these? Do you think they are any good? I try to clean my cat's teeth, but it is very difficult so I don't get to do it often. I would like to know what other things I can do, in addition to trying to brush her teeth.

Teeth cleaning should when possible be left to the vet. Otherwise you could be seeking treatment for your injuries I have never heard of the drops though, Gives me something to ask the next time I visit the vet.

I have tried the rinses with mine cat and dog and neither liked em... I am not about to attempt tooth brushing at home .. instead I use tarter control treats and food

I really can't see how any added to drinking water can help. It would be so diluted. There are oral rinses for squirting directly into a cat's mouth. However, I've tried one of these and the cats hated it. A major struggle to use. It's easier to just brush teeth.

Thank you, everyone. I've had enough of buying products only to throw them out. You saved me.
