Fish tank - glass is scratched

[Kosla3]

I have bought the second hand fish tank. It was very dirty so start to clean it and unfortunately scratched the glass with ruby pad. It is not big drama but maybe someone have any idea how to polish it please ?

You can get glass polishing kits in most big box stores or online. If the scratches aren't too deep, most of them will do the trick.
