Concrete
Cleaning:
Wipe the surface with a soft cloth and mild soap (such as dish soap diluted in warm water). Avoid abrasive or acidic products.
Stubborn stains or small scratches: For stubborn stains or a slightly chipped corner, you can gently sand the surface with fine-grit sandpaper (between 120 and 220). This method revives the finish without damaging the item.
Tip: Always test on a small, inconspicuous area before sanding a large surface.
