For three decades, Commack Hand Car Wash and Detail Center has broadcast a single mission from its red-and-white awning: 100% Hand Car Wash. Cars roll into tunnels where technicians spray, suds, and wash exteriors, applying tire protectant or wax to maintain the squeakiness for weeks to come. On the inside, vacuums ferret out grime from every upholstered crevice, and dashboards breathe free of dust. Commack's treatment ensures that delicate auto bodies have no physical contact with machines, reducing flashbacks of when they had to sit on Mechagodzilla's knee at Christmas.
