The answer to 'pressure washer stained' is that a pressure washer can sometimes leave behind stains or discoloration on surfaces. This is often caused by using the wrong cleaning solution, applying too much pressure, or not properly rinsing the surface afterwards.
Common symptoms include faded, streaked, or discolored areas on the surface being cleaned. This can happen on siding, decks, patios, and other outdoor surfaces. The good news is that these stains can often be removed with some additional cleaning or by adjusting the pressure washer settings.
