One, How to clean exterior wall bricks effectively
It is best to hire a professional cleaning company for cleaning exterior bricks. Exterior cleaning is a high-risk activity. Exterior cleaning not only requires the wall surface to be clean and tidy, but also ensures the safety of the cleaning personnel. Below, we will look at the steps for cleaning exterior bricks:
1. First, select a secure location on the rooftop platform where a rope can be anchored. Ensure the rope is looped several times and subjected to repeated pulling and load testing to guarantee complete security. Place rubber pads at the necessary locations (where there are edges) to prevent rope breakage due to friction.
2. Secure the rope in the U-shaped hook on the swivel platform, then hang the bucket and add the cleaning agent. Avoid overfilling to prevent spills and waste. Ensure that all necessary cleaning tools are readily available. The rope has a special knotting method that prevents the platform from slipping. Cleaning personnel can freely operate and control the rope.
3. Personnel must be present on the upper and lower levels to ensure safety and prevent accidents.

If the exterior wall tiles are accidentally splashed with tea, coffee, beer, or contain stains from ice cream or grease, they should be cleaned immediately. If necessary, a small amount of bleach can be added. After pouring the bleach solution onto the stain and letting it soak for approximately 30 minutes, wipe clean with a cloth. For stains that have been on the brick surface for a longer period, the soaking time with bleach should be extended accordingly.
2、Dilute hydrochloric acid or dilute nitric acid solution
If the brick surface has ink, cement, or other residues, it can be cleaned by applying a diluted solution of hydrochloric acid or nitric acid, followed by rinsing with water.

If the material is contaminated with paints, coatings, or other pollutants, a specialized cleaning agent should be used, which can be purchased at building material markets.
