Q. why should I Keep my car clean?

A. Having a clean car obviously keeps your car looking newer longer. There are other, more technical reasons to keep your car clean. Dust, sand, and road grime are minuscule, abrasive particles. They attach themselves to your paint and finish. If your car is not washed on a regular basis, these particles can literally scratch the finish of your car. Some substances such as bird droppings or tree sap can even eat through your clear coat, leaving your car finish unprotected and vulnerable to additional wear and tear.


A. Any Vehicle with;

  • Previous Damage (loose moulding/emblems, blistered, peeling or faded paint, pin stripping, wrap signage etc).
  • Damaged or faded soft tops
  • Aftermarket accessories such as bug shields & bonnet protectors
  • Objects on Antennas (balls, flags, etc.)
  • Cracked Windshields
  • Power antennas that won’t lower
  • Tradesman, Ski and Bike Racks including side/rear mounted awnings
  • Racing Fins and Spoilers

Q. HOw Long does it take to get a car WASH?

A. Grand Wash Auto uses a conveyor that keeps cars moving even if there are a few cars in line. The entire wash cycle lasts no longer than “THREE MINUTES” and since there is no waiting for the car in front of you to finish, you will rarely spend more than five minutes from the time you pull in to when you are back on your way.

A. Grand Wash Auto wants nothing but the best for its customers.  Even more important is our obsession with the goal of exceeding our customer’s expectations by offering the most comprehensive 100% guarantee in the car wash industry. It covers-

In fact, in many ways, washing your vehicle at Grand Wash Auto is safer than washing it by hand.

Q. Will my wheels be clean?

This process removes dirt, brake dust and road grime and brightens the walls of your tyres. Grand Wash Auto does not use corrosive or acid chemicals and only soft cloth material so your alloy wheels are perfectly safe.

Q. will my car be dried?

A. At Grand Wash Auto we use powerful “dryers” or "blowers" at the end of the wash cycle to remove most of the water used to rinse the car in the car wash. There will, however, always be some amount of water left on the car. Because we use a Spot Free Rinse comprised of pure water from our Reverse Osmosis filtration system, any remaining water left on the car will dry within minutes without leaving spots on your car.

Q. Does grand WASH AUto really want to hear me complain or compliment?
