how to polish marble by hand

Of course, I'd be happy to help! Polishing marble by hand takes a few steps. Starting off, you need to clean the marble with soapy water and a cloth, drying it thoroughly after cleaning.

After drying the marble, the next step involves sanding to remove any scratches. You should use fine-grit sandpaper, and gradually move to using higher grits (like 800, 1500, 2000) for a good polish.

Following sanding, you want to buff the marble. This is achieved with a soft cloth and a marble polishing compound. Rub the compound into the marble in a circular motion until the desired shine is attained. Make sure to wipe away residual compound afterwards.

That's completely understandable. Sometimes, tasks can seem daunting, but remember it's okay to take breaks, and come back to it later. You can tackle this process bit by bit, and remember, perfection is not the goal, learning and experiencing is. And if it continuously feels overwhelming, don't hesitate to seek help from a professional.
