It is vitally important that you understand that you cannot use any acidic products on marble which does make some cleaning jobs more difficult.
For Cement Staining. This is a difficult issue to resolve with a marble because you must NOT use any acid based products. Cement residues are usually removed with an acid but you must NOT do this. You can use Powerase diluted 1:3 with water to help remove cement. You will need to scrub with brushes, nylon pads or machinery (on larger areas). Be careful not to damage the stone by scrubbing too vigorously. Rinse well. Always do small test areas first.
For Efflorescence (white mineral salts that can appear on a stone as it dries) the same issues will be encountered as when removing cement residues from marble because you cannot use acid. Fortunately, efflorescence is not often an issue on limestone. If required, you can use Powerase diluted 1:3 with water to help remove efflorescence. You will need to scrub with brushes, nylon pads or machinery (on larger areas). Be careful not to damage the stone by scrubbing too vigorously. Rinse well. Always do small test areas first
For Mud you will find that Powerase is very effective. A wet vacuum cleaner can be used to remove the cleaning solution and rinsing water which will do a much better job than using a mop or a hose.
For Algae use Biorase followed a few days later by Algerase. You will find a more specific article on removing algae by clicking here.
For Leaf and Plant Stains use Biorase.
For Bird Droppings use Powerase first then treat any remaining coloured stains with Biorase. You will find a more specific article on removing Bird Droppings by clicking here.

The best methods for removing mud and general dirt from stone and tiles.
Leaves, trees, petals, seeds, pollen and cuttings can stain stone. Leaves can release tannin as they turn brown which is a very powerful dye. Tannin is the stuff in tea that can stain the inside of a glazed china teapot so it's not surprising that it will stain stone.
You will be using Biorase which is usually very effective.
Various food and drinks can stain stone. Oil and grease from a BBQ, children dropping ice cream or adults spilling a glass of wine can cause marks that are tricky to remove. Colours contained in food and drink can leave "coloured marks" even after normal cleaning. We are usually successful in removing this type of issue.
You need some knowledge to understand how to use a pressure washer in order to acheive the best results and avoid potentially serious damage.
