Why use touchless foam for wash a car
Notice all those small swirl marks and scratches in the paintwork of a car after a traditional car wash? A fair amount of these will have been caused by the cleaning process. All the lubricating car shampoos in the world will only go so far, there is always that small chance you'll drag a tiny piece of grit across your bodywork and leave a nasty scratch. There are only two ways to prevent this; never drive your car again, or to look into the touchless wash method.
As the name suggests, a touchless car wash removes the manual cleaning aspect from car cleaning, i.e. you. Instead of getting busy with your hands, you apply all the products via a pressure washer and let them chemically clean the car. This will totally eliminate any chance of scratches as the most aggressive force you'll be applying will be pressurised water.
There are even automated touchless car washes that thankfully skip the massive flailing bristles and instead use strong cleaners to remove dirt. These do however often use aggressive traffic-film removers (TFRs) which can strip away protection and so are best avoided, like any automated car wash.
How do I do a touchless car wash?
Before attempting a touchless wash, make sure that your car's bodywork is cool and is parked in some shade.
As you'll be increasing the dwell time of any applied products to compensate for the lack of physical agitation, you'll need to take some steps to stop the chemicals from drying on the paint. It's for this reason it's also advisable to work either in the morning or late in the afternoon and avoid the midday heat.
Touchless car wash step one: Rinsing
The first task will be to remove any larger chunks of dirt using the power of a pressure washer.
This stage is incredibly simple, spray every inch of your car with water ready for the next stage. Your biggest consideration here should be ensuring you set the pressure washer to below 140 Bar to not pose a threat to the car's paint.
