Look at the average car on a sunny day and you’ll probably see that every painted panel is scarred with small scratches and swirls that contribute to a rather flat-looking finish that can make even the most exciting colour look a bit dull. It may surprise you to hear this but the majority of those small scratches will have been caused when the car was being washed.

Think about it for a moment, why is there a booming market for grit guards, drying towels and shampoos all designed to minimise the risk of leaving small scuffs in a car’s paintwork? As you run a wash mitt over a car there is always a chance that a tiny piece of grit will get sandwiched between the two and leave a nasty scratch in the clear coat. It’s not the end of the world but get enough of them and you’ll need to polish your car.
Thankfully, there is a clever washing technique you can adopt to ensure that your car won’t get scratched; a touchless wash.

What is a touchless car wash?
As the name suggests, you don’t ever touch the car during the washing process. Instead, you replace your hands with a foam lance and pressure washer to douse the car in chemicals and let them do the cleaning. his will totally eliminate any chance of scratches as the most aggressive force you’ll be applying will be pressurised water.
How can I do a touchless car wash myself?
Your first check before attempting a touchless wash should be how dirty the car is. Heavily dirty cars won’t be suitable because the baked-in contaminants will need some mechanical scrubbing to shift, chemical cleaning alone won’t cut through them. If on the other hand, your car is only slightly grubby (or better yet protected with a good sealant), then a touchless wash will be entirely possible.
You’ll also need to make sure the car is out of direct sunlight and the panels are cool. The reason for this is that you’ll be increasing the dwell time of the cleaning products so they can properly work so you’ll need to prevent the chemicals from drying on the paint.
Step one: Rinsing
Using a pressure washer, wash the car with nothing more than water. Your goal here is to soften and dislodge larger bits of mud and grime making your life easier once you start using cleaning products. Most domestic pressure washers won’t pose a threat to the paintwork but remember 140 Bar is more than enough to clean a car.

Step two: Prewashing
This is the fun bit, it’s now time to cover the car in a detergent-filled foam to lift and loosen any dirt the pressure washer just couldn’t tackle. Snow foam is incredibly easy to use and will gently lift away deposits that may pose scratch risks, just make sure to wash it all off before it dries and check the recommended dwell time to get the most from it.

Step three: Washing
This step is the first main difference between a regular wash and a touchless car wash. Instead of filling buckets with shampoo, you’ll need to find one that can be applied via a foam canon. Once sprayed on leave the shampoo to dwell for a couple of minutes before rinsing off with water. There’s no need to scrub with a detailing brush, the detergents in the shampoos should be strong enough to properly clean the car while you watch on.

Step four: Protecting
An optional but worthwhile step, adding protection using a pressure washer is a cool time-saver and will help keep your car cleaner for longer. These sealants may only last a couple of weeks at most, but they’re easy to apply and will produce a noticeable difference. Follow the instructions on the bottle and remember to thoroughly rinse off any excess product.

Step five: Drying
Potentially the biggest shift, if you decide to do a touchless wash, will be drying the car. Microfibres are great but still carry a minute scratch risk which is why air will be doing the heavy lifting here. For the ultimate peace of mind, a proper car dryer will provide warm, filtered air to carefully dry a car, but can be quite expensive. Pet dryers or leaf blowers are much better value for money and do the same job.
