Solution for stain Walkways

First remove, as far as possible, surface substances with a spoon.

Immediately wet a cotton cloth with cold water, wring it out and place it over the stain.

Leave the cotton cloth to dry, without looking. When the cloth is saturated, replace it with a fresh one until the stain doesn't give off anymore dirt. Then leave the cloth until it is completely dry.

Spray James Water onto a cotton cloth and treat the stain using wide sweeping strokes.
