2. Touch Free Wash

OPERATION

    Cars are usually prepared by the car wash operator Hand applied detergents to difficult areas - wheels, front bumpers, bonnets, mirrors and windscreens.

    Sometimes only spray applied detergent to bumper and wheel area.

    Step 1 - Car Tunnel

    Pre Soak is applied to the car as a “Sloppy” foam,

    contact time is critical as the foam must hold on surface to allow soils to soften.

    Step 2 High Pressure Wash Zone

    Only water used on the vehicle

    NOTES

    Step 3 Drying Agent

    A cationic wax is applied to the surface of the vehicle to enable the water to “bead” so that high pressure air can blow the water off the car.

    Step 4 Colour Foam Stage - Optional

    Some sites have a colour foam stage where foam of three different colours is applied to the car in stripes and then rinsed off. This application of foam provides extra cleaning but also provides some UV protection through the depositing of a UV absorber.

CHEMICAL APPLICATION

    Chemicals are directly dosed directly into delivery line by a pump system. Chemical supply is separate from manual bays.

3. Roll Over Type

Similar to the Touch Free Washes, except a series of brushes are used in the wash stage. Usually no

    “Prep” work required.

    Step 1 High Pressure Knock Off

    Low detergent concentration, but an essential part of the process. If solids are not removed properly, paint work on the vehicle can be scratched or soils can be embedded in brushes making them “abrasive”

    Step 2 Main Wash

    Increased detergent concentration to remove road grime. This stage is where brushes are used

    some tunnels also have brushes for wheels.

    Step 4 Drying Agent

    Similar to Touch Free Designed to “bead” water for

    better “blow off”.

    Step 5 Wax Stage Optional

    Some Tunnels have a wax stage to apply a fine film of protective wax to the surface of the vehicle

    Step 6 DI Rinse

    DI Rinse to help provide a spot free finish

    Step 7 Air Blow Off

    Air Jets used to blow off excess water from the vehicle

PRODUCT APPLICATION

    Products generally dosed directly into water feed lines to each stage. Some systems have recycling tanks

    of 1000 litre capacity to re-use wash water.
