Surface dirt, leaf debris and bird droppings are more visible on lighter porcelain like Cathedral Beige than on darker shades like Anthracite, simply because of contrast. The good news is porcelain is non-porous, so dirt sits on the surface rather than soaking in, and routine sweeping plus an occasional wash with warm water keeps it looking fresh. For deeper cleans, a pH-neutral patio cleaner removes anything stubborn without affecting the colour.
