Cleaning solutions for brick patios

A brick patio makes a beautiful addition to the exterior of any home. But brick patios become dirty and stained over time due to their constant exposure to the elements. Clean a brick patio with a variety of cleaning solutions. Start with the mildest cleaning solution before progressing on to stronger solutions. Begin with dish soap, moving on to chlorine bleach, followed by trisodium phosphate and, as a last resort, muriatic acid.

Add a few squirts of non-ammonia dish soap to a bucket. Fill the bucket with hot water.

Wet down the brick patio with water from the garden hose.

Dip a stiff scrub brush into the bucket of cleaning solution. Scrub the patio thoroughly with the cleaning solution.

Rinse the patio with plain water from the garden hose.

Fill a bucket with a bleach and water solution. Use 1 part chlorine bleach to 9 parts water.

Dip a stiff scrub brush into the bucket of bleach solution. Scrub the patio briskly with solution. Allow it to sit on the patio for about 10 minutes.

Rinse the patio with plain water from the garden hose.

Fill a bucket with 1 gallon of hot water. Add ½ cup trisodium phosphate and ½ cup powdered washing powder. Allow the detergent to dissolve completely into the water.

Wet down the patio with water from the garden hose. Scrub the brick patio with a stiff scrub brush and the cleaning solution. Allow it to sit on the patio for about 10 minutes.

Rinse the patio with plain water from the garden hose.

Mix a solution of 1 cup muriatic acid and 1 gallon water into a plastic bucket. Put the water into the container first and then add the acid.

Dip a long-handled scrub brush into the bucket of acid solution. Scrub the patio thoroughly with the solution.

Rinse the patio with water from the garden hose. Do not let the acid solution sit on any part of the surface for more than three minutes.

Mix a solution of 1 cup household ammonia with 1 gallon of water in a clean bucket. Scrub the patio with a clean scrub brush and the ammonia solution to neutralise the acid.

Warning

Use extreme caution when working with muriatic acid. Never let the acid solution come into contact with metal tools or parts. Wear clothing that covers your arms and legs, as well as rubber gloves, when working with bleach, muriatic acid or trisodium phosphate. Never pour muriatic acid into an empty container. Never mix chlorine bleach and ammonia. The results could be toxic. Never mix muriatic acid with any other chemicals or cleaners. Cover nearby landscaping and plants with plastic sheeting to protect them from the cleaning agents. Have a steady water source available when working with muriatic acid in case of skin contact. Sprinkle baking soda on any acid spills to immediately neutralise the acid. Dispose of muriatic acid properly by taking it to your local hazardous waste recycling centre.
