While brick walls
tend to get dirty pretty fast, it is fortunately an easy task
to clean the brickwork. And best of all, you don't need any
expensive fancy brick cleaners to do it.
First, mix a solution
of hot water and all purpose cleaner. Then clean the wall
using a hard bristle brush. If it is outside, you can rinse
with water.
If the mortar work
is dirty as well, when you finish with the brickwork, add
bleach to the solution, then clean the mortar.
