Aesthetic Appeal:

It's a well established fact that cleaning brickwork and clean stonework is visually appealing. In some cases, moderate and evenly spread soiling in confuction with a high contrast mortar can give a striking and aesthetically pleasing appearance. It's important not to over do it with masonry cleaning as the products used are extremely strong. Over use or over extended application times can 'bleach' the coilour from the brick. If lashed on without care, it can create 'dribble' marks.
