Different surfaces on your home require different approaches to properly clean and protect. For example, concrete can be pressure washed because of its strength and durability, while more delicate surfaces like natural wood and roof shingles should be soft washed to avoid damage. The wrong cleaning method can be ineffective in removing stains from these kinds of surfaces and can result in damage to them. That's why you should always work with a professional who knows how to assess a surface and use the best method to clean it.
