FAQs

  • Yes, many patio cleaners can be used on decking, but you need to choose a product that is specifically labeled as safe for wood. Decking materials can be more sensitive than stone or concrete, so it’s crucial to follow the instructions and do a patch test in an inconspicuous area to ensure there’s no discoloration or damage. Products labeled as bleach-free and acid-free are the best options to use on decking, as they are gentler on wood surfaces while still effectively cleaning.

  • Patio cleaners typically contain active chemicals, such as surfactants and disinfectants, that work together to break down grime, algae, moss, and green mould. Surfactants reduce the surface tension of water, allowing the cleaner to spread more evenly and penetrate deeper into the surface. The disinfectants then work to clean and sanitise the area, effectively removing algae and moss. Rain and weather conditions will continue to wash the loosened debris away over time, usually taking about four weeks under normal UK weather conditions. Some products also include inhibitors that help prevent the regrowth of moss and algae for a period of time.

  • Look for patio cleaners that are labeled as pet-safe or non-toxic. Products that use biodegradable ingredients are generally safer for pets. Always allow the treated area to dry completely before letting your dog walk on it.

  • Choose a patio cleaner that is specifically marked as safe for plants or biodegradable. These patio cleaners are formulated to minimise harm to surrounding vegetation. However, it’s best practice to avoid spraying plants directly.

  • The best time to use a patio cleaner is during mild, dry weather when there is no rain forecast for a few days. This allows the cleaner to work effectively without being washed away prematurely. Early spring and late summer are ideal times for a thorough cleaning, helping to remove the build-up from winter or summer usage.

  • The best patio cleaner depends on your specific needs. For tough stains and heavy moss or algae growth, a more powerful chemical cleaner might be best. For routine maintenance and minimal impact on the environment, an eco-friendly cleaner is a good choice.

  • Biodegradable patio cleaners such as Patio Bright will not kill weeds. Brands that contain bleach or acid may kill weeds or damage contaminated foliage. However, patio cleaners are not specifically designed as weed killers, so for persistent weeds, you might need a dedicated weed control product.

  • Most patio cleaners should not damage artificial grass, but it’s important to check the product label to ensure it’s safe for synthetic materials.

  • Patio cleaners will remove moss from surfaces. Surfactants and disinfectants disrupt the moss's development, effectively cleaning and sanitising the area. This makes it easier to wash away the moss without causing damage to the underlying surface.
