High Pressure Washing

Always flush from the bottom up when washing a high-pressure car

Allow the foam and degreasing mixture to work for a few minutes before starting to Bilvask at high pressure. And here it is important to know that now you should wash, not rinse. These are two different things.

When we wash with high pressure, we combine pressure and water from the high pressure washer, with soap and chemicals that are on the car. That is why we always flush from the bottom up. This is how you get the full effect of the soap on the car and the power from the high pressure washer. If you start from the top, which many consider natural, you will lose this effect by the water running down into the soap and neutralizing it before the pressure comes.

Another advantage of rinsing from below is that you obviously see better where you wash and avoid “weekends”. Only wash one panel at a time. For example. A door, a screen, etc. This gives you good control over where you wash.

When you wash high pressure, it is ideal to have a width of the jet of approx. 30-40 cm. Many washers on the market only come with a 30 or at best 40 degree nozzle. My advice is to switch to a 60 degree nozzle. This gives you better washing with the washer you have, while maintaining the gentleness by distributing the power as mentioned earlier.

Flush the car

When you have finished high-pressure washing, you will see that there are remnants of soap here and there. Therefore, flush the car an extra time. This time you can flush from top to bottom, as the purpose of this flushing is only to remove chemical residues.

Touch wash

Now is the time to bring out the bucket and a good washing glove or sponge. The purpose of this was his only to remove the static film, so this round goes quickly. Wash one panel at a time, and when we wash with a sponge / washing glove, we wash from top to bottom. This should be / is as easy as wiping dust off the body. Make sure you take plenty of soapy water in the glove / sponge and often dip in the bucket. It is important that it slides easily over the panel.

Rinse well and long and a little more

Soap water must not be left on the paint. This can create ugly stains, which can be difficult to get rid of. Therefore, rinse well here you can actually use low pressure to your advantage. I.e. only the garden hose.

Always dry the car

It is a good habit to dry the car after washing. This prevents water stains or stains from appearing on the paint, which does not look good on a freshly washed car.


A smooth surface does not adhere to dirt. I almost always use a quick wax or a spray sealer after washing. There are many types on the market, and in recent years there have been several types to be used on wet cars. This means that you actually spend “no time” to give the car a protective layer, as you will eventually dry anyway.

A car that has grown will not stick to the dirt so easily, and you can then, as I mentioned in the introduction, sometimes get away with non-contact foam washing. Regardless, it is always faster and easier to wash a car with good protection.

Some precautions

  • Never stand in the sun and wash a car
  • Make sure that the body has cooled down (if it has just been in the sun)
  • Do not allow degreasing or soap to dry on the paint. If you are unlucky, apply more soap / degreaser before rinsing
  • Always wipe the car with a microfiber towel after washing
