Car washing is a relatively simple matter, or it can be a whole science if you will. When I wash a car, it is a combination of a necessary evil and a relaxation from the hustle and bustle of everyday life. I always wash with high pressure, not necessarily because.
Foam makes car washing more fun
Once you have invested in a high pressure washer, foam gun is a small additional investment that increases the usefulness of high pressure washing considerably. And by that I mean foam cannon and not “soap dispenser” that often comes with the high pressure washers. (I never understood the point of this). Foam cannon lay thick foam, which “clings” to all vertical surfaces. This gives the effect that the soap Bilvask has time to dissolve the dirt, so that when you bring the power from the high pressure washer, you will actually wash away the dirt and not just rinse off the “top layer”.
How to choose the right washer
Forget bar or pressure, it is the amount of water that is important. How many liters does the washer deliver per hour? Most “cheap-washers” deliver around 4-450 liters per hour, while if you have one that washes well, you should up to a minimum of 5-600. And I’ll tell you why:
A high pressure washer’s worst enemy is air. You have the pressure in the washer at the end of the nozzle and then the air resistance starts to “kill” the pressure. The less water, the faster the pressure is killed. I therefore recommend 550-600 liters per hour, but a minimum should be 500 l / h.
Wash in width
This may sound a little strange, but what I’m trying to say is a bit the same thing I’ve been over. When we Bilvask, it is not primarily the pressure that is important, at the same time as the pressure is important. Maybe there was total confusion? I’ll try to clear up the confusion.
As mentioned, the pressure the manufacturer states for the high-pressure washer is approximately that stated by the nozzle, where the opening is 0.8 mm. This is such a small opening that it is completely impractical (and harmful) to wash the car with. You may have heard that you should keep a good distance when washing the Bilvask car with high pressure? We do this to get enough scattering on the jet and thus get the pressure distributed.
Another and smarter way to distribute the pressure is to use a nozzle that gives a wider spread. By using a nozzle with a 60 degree spread, you will get a good distribution of the pressure, and you can keep a distance that means that the air does not “kill” the pressure. You wash safely with while maintaining a good pressure.
How to wash the car with high pressure
As I said, I mostly wash cars in a combination with high pressure and bucket washing, and it is this method I want to take you through here now. When I say “mostly” this means that there may be days I just foam and rinse. The car will then be 90% clean and good enough for the next trip. The reason why we should have touch washing in addition to high pressure is to be able to remove the static film that is left on the car. It does not sit hard, but it needs touch to remove it. Even on a well-grown Bilvask car.
I start by figuring out what to use in addition to the washer of course. If the car is very dirty, I always use degreasing. I choose a degreaser that emulsifies (mixes) with water. Not all degreasers do this, so you must take this into account when using degreasing. I will explain in the process itself later. Then I have good foam soap for the foam cannon, bucket and bucket shampoo, as well as a good washing glove. Some people prefer sponges, and that’s all right.
Before I insert the lower part (under windows) with degreasing, I rinse the car well with the high pressure washer, to remove all loose gunpowder. I can do this because I use a degreaser that emulsifies. I use WashKing WET Degreaser which easily emulsifies with the water that is on the car. Many other degreasers on the market do not have this effect, and the petro-based degreaser will then settle as a film on the surface of the water, and have a minimal effect. If you are unsure, or know you have a degreaser that does not emulsify, you get the best effect by placing the degreaser on top of dry dirt.
Always lay degreasing from the bottom up, and remember the rims.
Let the degreaser work for 2-3 minutes before applying foam to the outside of the degreaser and all over the car. Also add foam from the bottom up.
