Rust Spots On Costa Esmeralda Granite
I just had costa esmeralda honed granite installed in my kitchen. I have noticed that there is small rust like spots appearing throughout the granite. What could be the cause and what could correct it?

Hello Steve,
Costa Esmeralda can have enough mica and iron that would actually rust. This usually can be prevented with a good application of sealer. To remove the intensity of the rust mark, try “Iron Out” (available and home centers). Test it first in a small area because although it should reduce the mark, it may also etch the countertop surface a little; thus, removing the polished look.
I am not sure what you mean but appearing throughout the granite, so if the “Iron out” is not a practical solution, then I do not believe you have any other option but to seal the granite now to prevent further rusting.
Best wishes,
