1. General Cleaning 

The general brick cleaning from time to time is simple and can be done with just water and a mild bristled brush. Scrubbing the brick with brush for a while would help wipe a layer of dust, debris and mould that may have compound it. In most cases, the usual dirt and easy stains get wiped out easily with the help of water and little scrubbing. However, if the stains are tough and the layer of dirt doesn’t go away easily, don’t do scrubbing too hard as it may damage the brick. In such cases, adding a little ammonia to a bucket full of water used to cleaning bricks can be a good idea. It fragments the dirt particles and helps in cleaning the bricks off dust and stains easily. 

 


2. Removing Mould and Moss from Brick

The bricks that are exposed to water and are moist would inevitably grow mosses and mould over it. There are a few tools that you can use to get rid of moulds and molasses that grow over the brick in moist conditions. The tools that you may need to get rid of moulds and molasses over the bricks are high-pressure hose, garden hose, chlorine bleach, plastic spatula, nylon brush, and waterproof or rubber gloves. 

The process of bricks cleaning London in this case starts with using the garden hose initially to remove the not-so-stubborn moulds and moss before moulding to the stubborn moulds and molasses. The metallic spatula can be used along the process of using garden hose with pressure nozzle to scrape off layers and deposits of moulds and moss over the bricks. The water used for cleaning the bricks off moulds and molasses should be mixed with a cup of bleach. 

In order to ensure there are no negative surprises, you can experiment with a specific part of the brick to see bleach water reacts with bricks before carrying it out on a larger scale. If the brick reacts to the bleach water, it would most probably change the colour. The brush or a scrub can be used to get rid of mould deposits on the brick and if the moss is too stubborn to go away easily, using power washer can prove to be a good choice. 

If you plan to clean the brick with a garden hose or a pressure nozzle, make sure to not damage the brick. The pressure should not exceed 3,000 psi. It is a similar process you use to clean gravel driveways Essex from time to time.
