Washing your car is something that allows you to feel good while you are driving around because of the fact that you would know that anyone that looks at you will develop a positive impression of who you are in their brains. Cleanliness is a trait that anyone would be glad to inculcate into how they live, but it is crucial to recognize that there are wrong ways to clean a car as well as correct ones, and you would do well to learn the differences between the two.
A really common mistake that people make when they see how low pressure washing prices are is that they try to pressure wash their car without first understanding the proper way to do so. Suffice it to say that randomly shooting a jet of immense pressure in the general direction of your car will cause all manner of scratches and scuff marks, and that will devalue your car by a pretty large margin. That is why you should be careful while selecting the tip that you would add to the end of your nozzle, especially as far as car washing is concerned.
You should use the forty degree nozzle when you are washing the painted body of the car as well as the glasses. This disperses the jet into a wider spray which reduces the surface area that the pressure is hitting without actually decreasing the pressure itself. Try to switch to a twenty five degree nozzle for the tires and brake pads due to the reason that they will have much tougher pieces of dirt that require a more concentrated jet to properly knock them loose.
