Dirt and debris can accumulate on your landscape rocks as a result of daily exposure to the outdoors, dulling their appearance.

If your stone has developed a slight green tint, you should wash it.

How do you clean white gravel?

Some factors will have a greater impact on the appearance of your gravel than others. You may need to clean the gravel more frequently depending on the color and location of the gravel in your garden. Due to foot traffic, dirt is more likely to appear on footpaths, and gravel that is less exposed to sunlight or utilized near water features will develop algae on the surface much more quickly.

Marble and limestone, for example, are softer ornamental stones that may discolor more quickly than granite and quartz.

Garden stones are more likely to discolor due to dust and filth during dry seasons with no rain. A high-pressure garden hose, on the other hand, can quickly rinse dirt, algae, and dust away from any gravel color. Simply rinse the garden gravel with the hose on a low setting. The water will be absorbed into the ground beneath the gravel since it is porous.

The color white is one of the most popular ornamental aggregate colors. Polar White Marble Gravel’s beautiful, white tones are the perfect accent color to contrast with darker shades of slate, brickwork, or planting schemes, but they also look stunning on their own as driveways, walks, patios, or decorative borders.

Lighter colored garden stone, on the other hand, is more prone to lose part of its lovely natural bright sheen due to grime. The good news is that it is very easy to clean, and a simple wash with a high-pressure hose generally suffices.

If any dirt remains, softly brush the white aggregate with soapy water. Vinegar is an excellent natural alternative to dishwashing solutions for preserving the natural beauty of white garden pebbles and gravel.
