About Expert Power Wash
Expert Power Wash is a family-owned pressure washing equipment shop in Oregon City, OR, run by Tim and Kristina. Before we built equipment, we ran our own pressure washing business for more than ten years — so the parts and chemicals on our shelves are the ones we trust on real jobs.
Our storefront stocks thousands of parts, chemicals and supplies, most in-stock orders ship the same day, and when you call 503-403-6185 you talk to people who have run this gear.
