Each kind of brick requires different cleaning solutions to prevent damage and dicolouration. Since bricking can be easily damaged, it is advisable to start the cleaning with a milder solution and spot tests. The main problems with brickwork are:
- Organic growth-moss, mildew, algae, and weeds
- Chemical stains
- Lackluster colour
- Soot, oil, and grease stains
Some of the different classes of cleaners are:
Brick Cleaning Acid Solution
Acid-based solutions are the most powerful products for brick cleaning as they contain hydrochloric acid. They remove deposits, rust, and stubborn stains. Hydrochloric acid is dangerous as it can burn skin, plants, and vegetation.
There are specific instructions for mixing the acid cleaner before use. Do your research before using them. You must also be cautious when applying so that it doesn’t fall on any surrounding areas.
You must leave the brick acid cleaner on for about 10 minutes before washing.
Muriatic acid is the most popular solution for removing efflorescence from bricks. It is also a good concrete cleaner acid for stains, as well as an effective cement cleaner. Just browse muriatic cleaner UK to buy the best one.
It is readily available at home stores and is great for heavy-duty cleaning. But slap on some protective gear like bodysuits, gloves, and face shields.
Moss and Mildew Removers
Like block pavements, brickwork, especially on the exterior walls, is prone to organic growth like moss and algae. Furthermore, rear walls or brickwork that is not exposed to the sun regularly is susceptible to mold and mildew.
The British weather is mostly damp and overcast, the perfect breeding conditions for organic growth. Algae, mold, and mildew make your brick wall look dull and colourless. The ensuing dark and green spots mar the natural beauty of brickwork again got prematurely.
Bleach-based cleaning products are the most effective for getting the algae and lichen out. You can choose between the more toxic version that contains chlorine or a safer one like oxygen bleach.
Degreasers remove oil, grease, and soot stains commonly caused by fireplaces and furnaces. They don’t work for the more stubborn stains but usually get the grease and the soot out. Detergents and soap-based cleaners are common degreasers and are perfect for routine cleaning and maintenance.
Paint thinners remove paint from brickwork. They work for eliminating light paint layers and spots, not heavy ones.
The fumes from paint removers fumes are harmful if inhaled. Hence, take precautionary protective measures such as masks and gloves before using.
