Silverstar Car Wash - Sioux City Hamilton Boulevard

Silverstar Car Wash’s Hamilton Boulevard location is at 1700 Hamilton Blvd., Sioux City, IA 51103. The branch lists (704) 870-0250 and daily hours of 8 a.m.-8 p.m. The chain describes its conveyor wash as about three minutes once inside and says attendants prepare problem areas before the automated equipment. Free high-powered vacuums and prep towels are available with a wash; compressed air and mat cleaners are offered at select locations, so confirm availability here if needed.

The online pass menu lists Economy at $11.99 for one wash or $19.99 per month. Basic rises to $17.99/$27.99, Shine to $23.99/$33.99 and Protect to $29.99/$39.99. Higher levels add an undercarriage rinse, wheel cleaning, ceramic, RainX and graphene-powered paint sealant. A pass uses monthly billing without a long-term contract and can be used at any Silverstar location. Customers often praise attendants who take time with tough road grime and mention the useful vacuum and cleaning-supply area after the tunnel.

The local branch page advertises an introductory 30 days at the price of a single wash, then renews at the regular rate. Because the introductory offer and menu can change, check the posted terms before signing up. The Hamilton Boulevard location page has the current address and hours, while the wash-pass page lays out the tier differences.
