Hello,
I have a "Generic" vacuum pool cleaner shown in the image below. It has a support arm that rests on the concrete pool surface. This support is marked in red in the left photo.
Unfortunately this ball is worn out and the metal in it was rubbing on the pool floor and has left black marks. See photo on the right. I am assuming these are metal marks.
What is the best way of removing the black marks left by this exposed metal. The last photo in the post below shows these black marks. What is the best way of removing this mark. I tried metal scrubbing brush but that is not helping. There are some products like a pumice stone or localized acid cleaner available online. But I am waiting to hear back from experts on this forum to figure out the right product to but.
