Hi there, I’m looking for someone to wash a wall in my living room to remove a stubborn smudge and light staining. The wall is about 3 meters wide and 2.5 meters tall, with a standard plaster finish. I’d like a careful, non-abrasive approach using appropriate cleaning solutions and soft cloths to avoid any paint damage. Please confirm you have experience with wall washing, come prepared with supplies, and can protect nearby furniture. I’m aiming for a quick session, but quality matters most. Availability in the morning would be ideal.
