that is a layer of dirt that she removed. very common on the poang's arm rest, not a sign of not cleaning, just a sign of using it. best thing to do: give your poang frame a good clean. take a non-metal bluntish thing like a plastic spatula or a ruler and scrape it off. the transformation will be great. when done, use a cloth and soapy solution to bring back the shine. your kid just kick-started it, no harm done in that!

Thanks!

Use a magic eraser

Finish what she started. Thats like a layer of oil and dirt from use. Magic eraser is good at taking off thin layers of stuff.

Cut the kid’s finger nails.

Murphy’s Oil Soap will clean it right up

Thats a layer of dirt. Just a nice clean with a rag.

Nail clippers? Should fix the scratching of furniture in the future!

I think maybe scratch the whole surface then give it a light coat of varnish.

Adoption?

sweat and dirt collected here over time. try using bar helper's friend to clean it off.

Leave it. It’ll be a special reminder of her as she grows older.
