How To Use Exterior Wall Cleaning Agents Correctly

1. Preparation work
Before using exterior wall cleaning agents, it is necessary to clean the debris on the wall, especially dirt, oil, dust, etc. You can use water, detergent, and other items for cleaning.
2. Diluted cleaning agent
Before using the exterior wall cleaning agent, it is necessary to dilute the concentrated cleaning agent. Generally, the cleaning agent needs to be mixed with water in proportion, and the specific proportion can refer to the label or packaging instructions.
3. Spray cleaning agent
Pour the diluted cleaning agent into the spray can and spray it evenly on the surface of the exterior wall from bottom to top and from left to right, without missing any wall surface.
4. Placement time
The placement time depends on the degree of dirt on the cleaning agent and the wall, usually around 10-20 minutes. If the placement time is too short, the cleaning effect will be poor. If the placement time is too long, it will cause corrosion and damage to the wall.
5. Flushing the wall
After the storage time, rinse the wall with clean water, from top to bottom, and do not rinse in reverse, otherwise the wall may leave watermarks and cleaning agent marks.
6. Remove stubborn stains
If there are stubborn stains on the wall, a brush can be used for cleaning, but before using the brush, it is necessary to ensure that the cleaning agent is completely dry.
7. Protecting the wall
External wall cleaning agents may cause damage to the wall, so it is necessary to protect the wall before using the cleaning agent. Items can be covered in easily damaged areas such as corners and around doors and windows to avoid direct contact of cleaning agents with the wall.
