For black spots, products specifically formulated to tackle black lichen (those tiny black marks that colonise stonework) are most effective. Specialised cleaners, such as Kingfisher Building Products\' Max-Strength Patio Cleaner, work particularly well for removing black spots. For algae and green mould, concentrated solutions are excellent choices as they\'re specifically designed to tackle slimy green algae without requiring pressure washing or scrubbing.

Not necessarily. Modern patio cleaners, such as Kingfisher\'s Max-Strength Patio Cleaner, are designed to work without hours spent scrubbing on your hands and knees. Many quality cleaners are formulated to work without a pressure washer, allowing for simple spray-and-go application. However, some heavily soiled surfaces may benefit from using a pressure washer to accelerate results, especially on deeply ingrained dirt.

Quality patio cleaners, such as Max-Strength Patio Cleaner from Kingfisher Building Products, once applied, will clean and protect your wood or stonework for an extended period. For preventive maintenance, using a sealer after cleaning can help ensure that future spills (such as oil, dirt, or moss) will be easier to clean the next time around. Regular seasonal applications (typically in spring and autumn) are recommended for high-traffic areas.

Safety varies by product. When using professional-grade solutions like Kingfisher\'s Max-Strength Patio Cleaner, always follow the application instructions carefully. If you\'re concerned about pets, nearby plants, or roaming wildlife, look for cleaners that are formulated to be gentler on the environment. It\'s best to cover nearby plants during application, and for maximum safety, saturate nearby shrubs and plants before and after application to minimise potential damage.

Driveway cleaners are typically formulated to handle tougher stains, such as oil and grease, which are common on driveways but less prevalent on patios. Versatile solutions, such as Kingfisher Building Products\' Max-Strength Patio Cleaner, are designed to tackle multiple surface types effectively. While some products specialise in either driveways or patios, premium cleaners from trusted brands can handle both surfaces with equal effectiveness.

First, clear furniture or any large items so they\'re not in the way. Give the entire surface a thorough sweep and remove any large leaves or debris that could become airborne once you start cleaning. For pressure washing, ensure your hose is securely attached to the tap and turn it on to release any air before switching on the power. Proper preparation ensures that Max-Strength Patio Cleaner can penetrate effectively, delivering maximum cleaning power.

Kingfisher Building Products\' Max-Strength Patio Cleaner is versatile and suitable for multiple outdoor surfaces. This professional-grade solution works effectively on patios, driveways, decking, fencing, paths, and other outdoor hard surfaces. The powerful formula tackles organic growth, stains, and dirt across various materials, making it an ideal all-in-one solution for comprehensive outdoor cleaning. Please always refer to the specific application instructions for different surface types to achieve the best results.
