The answer to 'pressure washer stained' is that a pressure washer can sometimes leave behind unsightly stains or discoloration on surfaces. This is often caused by mineral deposits, rust, or chemical residue in the water that gets sprayed onto the surface. Symptoms may include streaks, spots, or a general dulling of the finish.
To address this, you should first try cleaning the affected area with a mild detergent or degreaser, then rinsing thoroughly. If the stains persist, you may need to use a specialized stain remover or brightener made for pressure washers. It's important to follow the product instructions carefully and test on a small, inconspicuous area first. If the stains are severe or you're unsure of the best approach, it's best to call in a professional pressure washing service to properly clean and restore the surface.
