Things to Consider When Buying the Best Power Washer for Cars

You have already gone through the different options for the best power washer for cars. From the reviews, you may have made an idea of which washer you want to choose. However, before you make the final decision, there is one more step that you need to go through.

Since the power washer will be a long-term purchase, you do not want to go wrong. That is why we have mentioned some important considerations that will help narrow down your search. These considerations will also help if you are confused or unable to make a choice.

Pressure of Water

When you buy a power washer, you need to check the force of the water that it creates. It is because the cleaning of your car will depend on the water force. You will find companies mentioning the psi or pounds per square inch of their power washer. It is the value used to measure water pressure.

If the psi is low, then the pressure will be low and vice versa. Most people opt for the highest psi, thinking that it will clean better and faster. However, this a grave mistake since a very high psi can damage your car.

Depending on how you wish to use the power washer, the psi will vary. Sometimes a power washer with a low psi is all you need to have a clean car. For a consumer power washer used for residential car cleaning, a psi ranging between 1,300 and 1,800 will be enough.

Gallons per Minute

Another factor that is as important as the psi is the GPM. GPM means gallons per minute which measures the water volume. It gets used to determine how much volume of water is going through the power washer.

Generally, it is better to have a higher GPM since the water force will also be better. If the water volume is low, then the force created will not be much. Having a high GPM will make the cleaning faster and efficient.

The psi and GPM of a power washer are directly proportional. If the psi is high, then the GPM will also be high and vice versa. The GPM for machines used for residential purposes will be somewhere around 1.5. You need to check both the psi and GPM when buying your power washer. Also, your water source needs to support the GPM of the power washer you choose.

Source of Power

The power source for each power washer is also different, and you need to see which one will be the most suitable for you. There are electric washers and gas washers, and each of these has its advantages and disadvantages.

If you need a power washer that needs less maintenance, is affordable and lightweight, then you could choose an electric washer. They also have a low noise level which is great for a congested neighborhood. Moreover, they do not cause air pollution, but you will be restricted to a certain area.

Since electric-powered washers have a cord, you cannot move beyond a certain point. On the other hand, gas-powered washers give you the freedom to use them wherever you want. However, the maintenance of the gas-powered models is quite high. They are also very loud and a major source of air pollution.


Do I need to connect my pressure washer to a water tap?

A water source is necessary to connect your power washer. Generally, people use any water tap located outside as their water source. You will also need to use a garden hose to connect the power washer to the water tap. Depending on how far your car is from the water tap, you might need a very long garden hose.

The diameter of the hose is generally ¾ inch, or you can check out your particular water source and power washer. If you do not have any water tap outside in the garden, there are many other alternatives. You can use your washing machine tap as your water source.

The washing machine tap structure is similar to that of your outdoor tap. That means you can attach the hose to it and get water. If possible, you can also use your bathroom or kitchen taps to withdraw water. However, for these, you might need threaded adapters that can fit.

Before you buy a power washer, ensure that you have the right water source. If you do not have a suitable source, you may need to get one made. The easiest is setting up a water tap in your garden. This way, you do not have to connect one to the inside of your house.

Which detergent would be the most suitable for my pressure washer?

If you are cleaning your car every week or twice a week, there is no need to use detergent. Generally, detergent is not recommended for routine cleaning since the water pressure will remove all the dirt. However, it is better to add a little detergent to the water if you have tough and stubborn dirt.

In some pressure washers, you will find a separate tank where you can put the detergent. In others, you might need to suck the detergent directly from the bottle using a tube. No matter how you use your detergent, the real question is what detergent you should use. It is better to use a detergent formulated just for pressure washers to be on the safer side.

They are generally not foamy and will not create a slippery layer on the ground. It is quite easy to wash away the pressure washer detergents. They are also formulated to get rid of grunge and grease easily. You will also find detergents that are made just for cars.

Many people use dishwashing detergents, but that is never a good choice. These detergents could damage or block the pressure washer due to suds overflow. Since you have already invested in a pressure washer, it is advisable to invest in a suitable detergent for enhanced cleaning and machine longevity.

How do I know which is the best spray nozzle for cleaning?

When you buy a pressure washer, you will see that many packages come with different nozzles. These nozzles will give you different water pressures, and you will require them for different cleaning scenarios. You need to ensure that you use the correct nozzle color to get the desired spray pattern.

A red nozzle is suitable for spot cleaning and getting rid of dried elements or tough stains. This spray is very powerful and focused at one point. You can use this effectively on a hard surface like steel and concrete. Then you have the yellow nozzle that sprays at a 15° angle and removes tough stains, paint, dried mud, mildew, and rust. Use this on very sturdy surfaces.

The green nozzle sprays at a 25° angle and is the most widely-used nozzle. For car cleaning, the green nozzle is the one that you will be using the most. This nozzle clears away grime from cars and also removes leaves and mud.

If you want to clean any delicate part of your car, the white nozzle is the perfect one. It sprays water at a 40° angle and will rinse the water very easily. There may also be a black nozzle that sprays water at 65° degrees and gets mostly used with a detergent.
