Is your patio looking dull, stained or slippery? Stone King Patio Restorer & Cleaner is a professional-strength patio cleaner designed to remove built-up dirt, grime, algae and organic staining from natural stone and concrete paving. It helps restore the original appearance of your patio while making pressure washing quicker, easier and more effective.
Stone King Restorer & Cleaner was Approved in 2026 by Good House Keeping for being great on tough stains.
Unlike pressure washing alone, Stone King works beneath the surface to loosen stubborn staining before you start cleaning. Over time, dirt and organic matter become embedded within stone, making them harder to remove with water alone.
Stone King breaks down this build-up, so your pressure washer can work more efficiently. Many customers tell us it reduces cleaning time by up to three times compared with pressure washing on its own.
Whether you're refreshing your patio after winter, preparing your garden for summer, or giving tired paving a new lease of life, Stone King helps you achieve professional-looking results with less effort.

Before treating the whole patio, apply the product to a small, inconspicuous test area (approximately 1m × 1m). Saturate the surface thoroughly.
If enough product has been applied, you'll notice a colour change within around 15 minutes as Stone King begins breaking down dirt and organic staining.
Allow the product to remain on the surface for approximately two hours. This gives the formula time to penetrate deep into the build-up, making it much easier to remove during rinsing.
Lightly pressure wash the treated area to wash away loosened dirt and reveal a cleaner, brighter finish.
Stone King is suitable for use around the garden and is pet-friendly once the treated area has been thoroughly rinsed. As a precaution, keep children and pets away from the surface while the product is working and until it has been completely washed away.
