A brick patio adds charm to the exterior of any home, but its constant exposure to the outdoor weather elements will get it dirty. Whether your brick patio is plagued with mould, mildew, moss, algae or just plain dirt, give it a thorough cleaning to restore the appearance and keep it looking attractive.
Bleach has long been used around the home for cleaning and sanitising. It works well at cleaning and removing stains like mildew, moss and algae from a brick patio. Mix a solution of 10 parts water and one part chlorine bleach into a bucket. Dip a long-handled scrub brush into the mixture, and scrub it onto your brick patio. Rinse off the bricks well with water from the garden hose. Take care when using bleach; cover surrounding plants and landscaping and wear rubber gloves and protective eyewear. Also test it on a small part of the brick, and wait a week or so to check for any colour changes.
Oxygen bleach is an eco-friendly alternative to chlorine bleach and will remove dirt, algae, moss and mildew. A bit more scrubbing may be required to get the bricks clean, but there is no fear of harm to your plants and foliage. Mix a solution of oxygen bleach and water into a bucket according to the label's instructions. Mixing proportions will vary based on the concentration of the oxygen bleach. Pour the mixture onto the brick patio. Wait 10 to 15 minutes, and give the patio a thorough scrub with a stiff scrub brush. Rinse off the patio with water from the garden hose.
If your patio is dirty and not overtaken with moss or mildew growth, washing powder and water is a good choice for cleaning. Fill a bucket with 1 gallon of warm water. Add 1/2 cup of liquid washing powder, and mix it well. Wet down the brick patio with the hose, and pour the detergent mixture onto the bricks. Scrub with a stiff-bristled scrub brush, and rinse the patio to remove the soap residue. Some plants and foliage may be sensitive to washing powder, so cover them with plastic sheeting.
Brick Paver Cleaner
Commercial products are available to clean brick patios. These products are best for tough stains like oil and grease. Thoroughly clean the patio first by sweeping it with a broom and scrubbing it with warm, soapy water. Rinse off the patio well with the garden hose, and let it dry completely before using the patio cleaner. Follow the manufacturer's instructions for using the brick paver cleaner as this will vary among products.
