Common Chemicals

There are many chemicals used in exterior cleaning, each with its specific purposes and benefits. Here are some of the most common chemicals used in exterior cleaning:

1. Sodium hypochlorite (bleach): This is a common disinfectant and sanitizer used to remove algae, mold, mildew, and other organic stains from exterior surfaces, including roofs, walls, and concrete. It is often used in soft washing and pressure washing.
2. Hydrogen peroxide: This is a powerful oxidizing agent used to remove organic stains and odors, such as pet urine or blood, from exterior surfaces. It is often used in conjunction with sodium hypochlorite.
3. Phosphoric acid: This is a common ingredient in rust removers and is used to remove rust stains from exterior surfaces, such as concrete, masonry, and metal.
4. Alkaline cleaners: These are often used for heavy-duty cleaning tasks, such as removing grease and oil from concrete or metal surfaces. They are highly effective and can be used in both pressure washing and soft washing.
5. Citric acid: This is a natural and environmentally friendly chemical used for cleaning and removing hard water stains from exterior surfaces, such as windows, gutters, and other metal surfaces.

When using any chemical in exterior cleaning, it is essential to follow the manufacturer’s instructions and safety guidelines. It is also a good idea to test any chemical in a small, inconspicuous area before using it on a larger surface.
