How does National City's climate affect this service?
National City sits between San Diego and Chula Vista with significant industrial-adjacent grime, heavy auto-dealership corridor scope along Mile of Cars Way, and dense older residential. Commercial pressure washing on the auto-row inventory, restaurant exteriors, and industrial loading docks dominates the work.. South Bay sidewalks and driveways near the freeways wear diesel soot that reads as a uniform gray haze.
Should I seal my concrete after cleaning?
If you want the result to last, yes. Unsealed concrete is a sponge, oil, rust, and mildew sink in within weeks. A penetrating silane goes invisible and blocks absorption for 3 to 5 years. Acrylic 'wet look' seals give a richer, slightly glossy finish and last 2 to 4 years before needing a refresh.
What is the white haze that came back after it rained?
Efflorescence, calcium and mineral salts migrating out of the slab. Common on newer concrete (under 2 years) or slabs with grading that holds moisture.
