When I was researching wedding rings, I read that some people polished them every year. But the thing is that if you polish it, it has a mirror finish and every scratch is noticible. Then you have to polish it again and again, and as soon as you do, you inevitably get that first scratch that stands out like a lighthouse in a storm.
The other option is to have all the scratches blend in until it becomes more like a stonewash finish. At that point, new scratches are just blended into the ring. No need to polish.
If you decide to use your shiny new toy, it will end up looking like the ones in the link below. Only you can decide if you're willing to accept what use looks like and whether you want to use it like a tool. Not everyone does, and that's totally fine. This hobby is different things to different people.
