A Guide To Waterless Washing Your Car

I have taken a little longer to create this post which was supposed to be a quick guide to a couple of products. As I went along this guide just got bigger and has grown substantially. My intention was to cover the growing trend of ‘Waterless Washing’ products and their processes. I think the term ‘Waterless Washing’, should actually be replaced with ‘Waterless Cleaning’ which I believe is a more of a technically correct term. The basic cleaning of the paint, will be supplemented with a raft of optional steps top create a show room quality clean vehicle; all without water. Some of the optional steps are dependant on the quality of your paint and the levels you want to go to in order to get that showroom finish. If you just want to clean the car and not worry about the best possible shine or protection, you can jump straight to the ‘Body Work’ first step, ‘Wheels’ for the second step and ‘Glass’ the third step then you’re done. If you want more shine, or a more thorough clean, then the optional steps will help you get to that showroom finish!

Where water is scarce, such as a hosepipe ban, or difficult to obtain due to the water’s supplies location (like living in flats or apartments), then ‘Waterless Washing’ is a process that can be your best friend. Waterless wash still needs to be used with care as the waterless process is not intended to clean a car if you have just driven through a swamp or go off roading!

This is contact cleaning, and very different to the contactless cleaning methods we are taught these days.

The whole car can be washed with specialised products including the wheels which are probably the most stubborn to clean even with water. Typically the brake dust, heat and road film will embed onto the wheels and the tyres in such a short space of time. But it can be done without to much hassle.

Glass cleaners are by nature a waterless product, ironically the majority of them may be diluted, but they don’t generally require you to wash the glass first.

Plastic Trims & Rubber, most of the time these are a liquid form application to rejuvenate the plastic back to black. The plastic should be clean and a waterless wash should be fine for the cleaning. Seals around the doors and frame of your car for wind noise or water ingress could also be waterless cleaned. If you have chrome of polished metal parts, like windscreen wiper arms, we will touch on that too. Rubber on the tyres ideally need to be cleaned first for a good shine.

I have listed out below quite a list of what you will or could need, the products, their application and their pros and cons. There are plenty of tips to help with your cleaning without water so you can get a show room shine.

School Boy Error

As virtually all the car shows have cancelled or postponed this year due to the Covid-19 running riot there is a slight chance that two are still going ahead. Pre-booking has been essential and due to obvious reasons they have been over subscribed with people wanting to show their cars, or just get out for the day to look at cars. With this in mind I decided to give my little lady a check over as I always, tyres, levels, leaks etc. When I opened the hood there was a strange and a rather ‘funky’ smell. After each car show season has finished I take out my water washer bag, or colostomy bag as they are often referred to and empty it out and put it back to stop the water going bad. The reason being this is a breeding ground for bacteria, the engine bay gets hot, then cold, then hot again. The end of last year I forgot to empty it out and clean it. So, when I opened the lid on the bag it wasn’t good news.

I disconnected the bottom pipe from the bag, quickly put my finger over the drain hole and took out the bag to the drain where it was emptied out. There was some black algae in there, which needed lots of rinsing, some citrus cleaner and more rinsing in order to clean it out properly. It took a while, but in the end it ran clean and smelt a whole lot better.

The back of the bag also showed some signs of being dirty. I started to clean it and thought I would share it with you, so this is sort of a third of the way through it. I started then general wipe down with some Meguiar’s multi purpose cleaner. Spray on let it dwell, then with a brush work it into the bag. Rinse and repeat a few times.

After a few applications it came back to white again after being dried out.

The bag is now empty and waiting for a refill before the next show. I do add screen wash to the bag which stabilises the water a bit. If I have to use the screen jets I don’t want any of the mixture running onto the paint and leaving a stain which I would have to buff back out again. After all the screenwash has a mixture of chemicals in the product to cut through the dirt and grime. Also in order to help avoid water spots or marking I only use de-ionised water, it’s cheap enough and the de-ionised water is also much better for your car’s cooling as well. I always keep a litre of de-ionised water in the trunk, just in case.

While I was waiting for the cleaners to dwell on the washer bag, I decided that my valve caps were also dirty. I didn’t realise just how bad they were. Only one of the caps here has been cleaned and waxed. Yes, I do indeed wax my valve caps too.

With the hood up I thought that the underside looked a little dull, so I waxed that as well, just because I can. I also think it’s quite a cool picture too.

What turned out to be an hour or so quick check up turned into a few hours of cleaning. Not that I mind really, just a bit disappointed with myself that I forgot to do it. It must be my age 🙁

Will I get to a car show this year? Will mother nature be cruel and rain on the day that one of the only car shows is due to take place next Sunday? Watch this space and find out!
