Identifying Types Of Stains
Next, identify the types of stains on your bricks. Common stains include dirt, algae, and mildew. White powdery stains are often efflorescence. Rust stains may also appear. Each type of stain requires a different cleaning method. Knowing the stains helps you choose the right cleaning solution. This ensures effective and safe cleaning.
