Abstract: BACKGROUND OF THE INVENTION 
In the last ten (10) years with the introduction of automatic car 
washing equipment, it has enabled people to keep their motor 
vehicles' clean with little effort.  
Long gone are the days of washing a motor vehicle by hand, shimmy 
drying the motor vehicle, applying an automotive wax to the car and 
then cleaning the windows.  
The old method of washing a car resulted in no wax products being 
applied to the windows.  
When a motor vehicle goes through an automatic car wash, the car 
body including windows are soaked with softening containments and 
detergents in the first run, followed by another run of water washing 
the car body surface and windows.  
A subsequent run then occurs when detergent is scattered over the 
body of the car including the windows. Then a subsequent run occurs 
by washing the motor vehicle body and windows with water to 
remove and liberate the detergent, dirt and grime.  
Then a subsequent runs occurs, which performs a splattered wax 
treatment to the car body and windows of the motor vehicle. Then a 
subsequent run occurs, which applies water to remove some of the
splatter wax, which has been applied to the motor vehicle body and 
windows.  
Then a final run occurs when the car is dried by air, removing excess 
water, however leaving residue of the splatter wax on the motor 
vehicle body and windows.  
The automotive splatter wax applied to the car body and windows, 
will add an extra layer of protection to maintain the paint protection 
and to maintain the motor vehicle shine from dirty rain water. Motor 
vehicle liquid splatter waxes as applied in car washing will protect 
the car for about one (1) week, after the wash.  
However, a side effect is the splatter wax is applied to the motor 
vehicle windscreen.  
The actual splatter wax which is applied to the motor vehicle will 
result in water beading on the motor vehicle windscreen, because 
car wax is hydrophobic, meaning that it does its best to avoid 
absorbing water.  
However, automatic motor washing will result in a wax build up on 
the motor vehicle's windshield. Too much automotive splatter wax 
on the motor vehicles' windshield will affect the driver's vision and 
also damage the wipers, when they come into contact with the 
automotive splatter wax application.
If the automotive liquid splatter car wax application is not removed, 
the use of wipers will cause the wax on the windscreen to spread 
wider and build up on certain sections of the motor vehicle's 
windscreen. This will affect the driver's vision by the creation of 
smudges and streaks.  
If a person uses an ammonia based windscreen cleaning product, it 
could possibly damage the window tint on modern day motor 
vehicles.  
SUMMARY OF THE INVENTION 
The present invention resides in the recognition that motor vehicle 
splatter waxing will result in a build-up of wax on the motor vehicle's 
windscreen and thereby affecting the driver's vision and also 
damaging the motor vehicle's wipers.  
The present invention, which consists of a 100 millilitres (ml) of 
Isopropyl alcohol, together with 200 ml's of vinegar, 200 ml's of pure 
water and 10 ml's of a dishwashing detergent (the product), will 
remove the motor vehicle splatter liquid wax from the motor 
vehicle's windscreen.  
Isopropyl alcohol dissolves a wide range of non-polar compounds. It 
also evaporates quickly, leaving zero oil traces. Isopropyl alcohol is a 
degreaser and has cleaning properties. Isopropyl alcohol will
breakdown the motor vehicle wash splatter wax, which has been left 
on the motor vehicle's windscreen and allow it to be removed.  
The vinegar provides an acidic composition, which acts quickly to 
break down the film such as dirt and grime that frequently 
accumulates on motor vehicle windscreens.  
Tap water, which contains dissolved solids and if used in this 
composition, would result in streaks and smudges being left on the 
motor vehicle windscreen. Therefore an element of this invention 
uses pure water to minimize smudges and streaks on the motor 
vehicles' windscreen.  
The use of Isopropyl alcohol, vinegar and distilled water acting 
together agitates and softens the wax, dirt and grime on the motor 
vehicle's windscreen and effectively removes the automotive 
splatter wax, dirt and grime from the motor vehicle's windscreen.  
The liquid automotive wash wax remover ("the product") is sprayed 
onto the motor vehicle's windscreen by the use of a small spray 
bottle, which contains 500 ml's of the product.  
The product would be applied using a prior art, "Melamine" which 
provides a cleaning efficacy using a layer of hardened thermo setting 
melamine foam (a formaldehyde- melamine- sodium - bisulphite 
copolymer, manufactured by BASF under the name "Basotect" for its 
superior scrubbing properties).
The use of melamine foam is used to soak up the automotive car 
wash wax removed when the product is applied in a circular motion.  
The use of the liquid car wash wax remover and the melamine foam 
causes the melamine to act like a super fine sandpaper. The abrasive 
foam and the liquid automotive remover product will loosen up the 
wax particulars, dirt and grime on the motor vehicle windscreen and 
open the micro structure of the foam as it removes the wax, dirt and 
grime into the foam and traps the wax, dirt and grime in the foam.  
Melamine foam is safe for the use on motor vehicle windscreens.  
Melamine foam has been recognised as having useful cleaning 
properties when wetted with water and rubbed against certain 
surfaces to be cleaned.  
The present invention provides for a cleaning wipe for use in cleaning 
automotive windscreens after proceeding through a car wash where 
a splatter wax is applied to the automotive body and windscreen and 
the melamine foam, together with Isopropyl alcohol, vinegar and 
pure water will remove the splatter wax from the automotive 
windscreen.  
The National Institutes of Health lists melamine foam as non-toxic.  
The melamine foam will only be suitable for a few applications of the 
liquid car wash wax remover as it tends to break down and 
disintegrate with repeated uses.
A roll of paper towels is then used as an absorbent to soak up the 
excess liquid automotive wash wax removed off the motor vehicles 
windscreen to allow a motor vehicle windscreen to be free of waxes, 
dirt and grime, and will allow the driver to have clear vision of the 
road and surrounding areas.  
The windscreen rubber wipers should also be cleaned with the 
melamine foam with the liquid car wash wax remover trapped inside 
it in order to allow the wipers to be wiped clean of wax, dirt and 
grime and allow clear vision when precipitation falls onto the motor 
vehicle windscreen.  
A disposable product consisting of a sachet of 100 ml of the product, 
Isopropyl alcohol, vinegar and pure water, together with a narrow 
piece of melamine, will be available from a product dispenser at the 
car wash bays.  
The sachet will be able to be opened and applied to the motor 
vehicles' windscreen and then the melamine foam will be used to 
apply the product to the windscreen in a circular motion, with the 
product loosening up the motor vehicle splatter wax, breaking down 
the dirt and grime, and the melamine foam will soak up the wax, dirt 
and grime, and then using the wiper blades to clear any excess 
product and also cleaning the wiper blades from any wax, dirt or 
grime.
