Self Serve Bays

Your car, your way. Wash, wax, and dry it yourself in our drive-through bays.

Two drive-through bays · 11′6″ overhead clearance · Vacuums and a carpet shampooer on site

In Every Bay

Six functions. One perfect DIY wash.

High-Pressure Soap

Blasts dirt and grime off your car's paint.

Wheel & Tire Cleaner

Breaks down brake dust and road grime on wheels and tires.

Foam Brush

Soapy foam for a hands-on scrub.

Hot Wax

An extra layer of shine and protection.

High-Pressure Wax

Seals in the clean with a protective glossy finish.

Air Shammee Blow Dryers

High-velocity air chases water off the paint, so there's less to towel dry.

Industrial-Strength Vacuums

Extract every bit of dirt and debris from your interior.

Carpet & Upholstery Shampooer

One shampooer is available to deep-clean carpets and upholstery before you drive off.

11′6″ Clearance

Built for the Big Ones

Room for more than the family car.

  • RVs, campers & travel trailers
  • Lifted & dually pickups
  • Boats & jet skis on the trailer
  • Motorcycles, ATVs & UTVs

Open 24 hours, right here in Derry.
