If you are here because you’re looking for the best pressure washer for your cleaning needs, then you are most likely convinced that owning one is indeed a good investment.

That’s great!

That means we can skip the sales talk and dig right into knowing which pressure washer unit is best for the specific job you have in mind.

A pressure washer is a must-have tool in every household, especially if you have tougher cleaning projects to complete.

Pressure washer applications are countless, for sure. But here, we’ll tackle the most common cleaning projects at home wherein a pressure washer is very useful.

Pressure Washing Cars and Trucks


Whether or not a pressure washer is safe to use on cars remains a debatable topic. Even experts seem to have varying opinions regarding this matter.

Unless you have a luxury car that a single scratch would cost a lot to get it repaired, we still insist on investing in the right pressure washer for the job.

We’ve outlined everything you need to know to get the best pressure washer for cars and trucks— and it’s actually simpler than you think!

The first rule is to stick to low-pressure units; that means you shouldn’t get a model with a PSI higher than 1500 PSI. For the flow rate, you can take your pick between 1.2 to 1.7 GPM.

The second thing to take note of is the appropriate nozzle to use. We can’t emphasize this enough.

One of the reasons why pressure washing has a negative connotation when it comes to cleaning vehicles is the fact that people just use the default nozzle that their pressure washer has.

The best pressure washer nozzle for cars is the white nozzle, which is the 40-degree angle nozzle. This one is highly recommended for car surfaces.

Pressure Washing Grills

If you love having barbecue parties at home, then there’s no doubt that a good pressure cleaner is of great use.

Barbecue grills are usually caked with grime and grease that are extremely difficult to clean if you are only using a garden hose.

A pressure washer can efficiently remove any traces of oil and grease from the metal frame. So, what’s the best pressure washer for grills?

Some suggest using a high-pressure unit because of the assumption that the higher the PSI, the better it can clean.

However, others argue that doing so is actually a bad practice. This is because the high pressure causes the grease to fly in every direction and can cause more problem.

Instead, use a pressure washer with a 2600-PSI level coupled with a 40-degree pressure washer nozzle.

It is also a good idea to use a foaming grill cleaner to break down the oil and grease on the grill grates.

Pressure Washing Wooden Decks

People are also hesitant to use pressure washer when cleaning their wooden deck.

Wondering why?

Well, the danger with pressure washing wooden surfaces is that the high pressure can push the water into the crevices of the wood. And if you’ll do a quick search online, you’ll find out that moisture can damage the wood material.

But here’s the trick that you should know:

It is safe to use a pressure washer for cleaning wooden surfaces, as long as you keep the PSI level to a minimum.

The most recommended PSI for wood surfaces is between 400-1000 PSI, but we think 1500 PSI is still a good pick, as long as you use the 65-degree spray nozzle.

The low pressure coming from the nozzle won’t force the water into the wood. Thus, water droplets only stay on the surface and can evaporate easily and quickly.

If the wood surface has a noticeable stain, it’s best to find another alternative to get rid of the stain that targets only the affected area. Do this before pressure washing the surface.

Pressure Washing Lawn Mowers & Other Outdoor Equipment

Yes, lawn mowers and other garden equipment need cleaning too – and the best pressure washer for the job is one that has at least 3000 PSI level and 2.5 GPM flow rate.

This combination will give you a total of 7,500 cleaning power, which is enough to thoroughly clean garden equipment.

If you have industrial equipment that need pressure washing, we suggest getting a pressure washer with a PSI higher than 3000. Somewhere around 3700 PSI to 4000 PSI is a great pick.


How to choose the best pressure washer for the job seems difficult to accomplish at first. However, knowing where you intend to use the machine and the ideal pressure for each cleaning project can help you determine the best pressure washer for your cleaning needs.
