However, it can be tempting for owners of cars, trucks, motorcycles and other vehicles to use them on their own vehicles—sometimes with disastrous results.

How likely is it that you’ll damage your vehicle if you give it a power washing? And what should you do if you think that might have happened already? Let’s take a look at some things you need to know before using a pressure washer on your car.


Pressure Washer Car Paint Damage:

When you think about all of the things that can damage car paint, it’s not surprising that one item on our list doesn’t immediately come to mind: Pressure Washers.

You might be thinking, Pressure washers don’t do anything to my paint! They aren’t abrasive! They just blast dirt off my car. And you would be right.

But there is something else at play here, and it isn’t good for your car’s paint job. It has to do with the temperature of the water.

The high-pressure spray from a pressure washer turns cold water into super heated steam when it hits your car.

This super heated steam causes thermal shock which melts away some of your clear coat or even worse, damages paint underneath.

So if you want to use a pressure washer on your car (and we know why you might), make sure you use warm water instead of cold and make sure that you keep moving so as not to hold in place long enough for thermal shock to occur.


How to Protect Your Car from Damage:

As we have already discussed that a Pressure washing can cause serious damage to your car. Avoid damage to paint, exterior surfaces, or any other part of your vehicle by practicing care when using a pressure washer.

When using a power cleaning tool can you damage your car with a pressure washer? Yes, you certainly can. In fact, you could even do significant enough damage that it would be impossible to repair without having to repaint it entirely.

If there is any question about whether or not your vehicle is made out of aluminum (the most common metal used in cars), then be very careful when using a pressure washer on it!

But if you’re certain that it isn’t aluminum, then here are some precautions you should take: Use an extension wand – By keeping yourself at least 20 feet away from your car while you’re cleaning it with water and soap, you’ll greatly reduce how much force is being applied to its surface and therefore reduce how much potential damage there is as well.

This 1800 PSI and WG605 machines are considered saver to use as they come with less PSI options and they are super easy to operate.


Tips To Help Prevent Damage:

Although using a power washer to clean your car isn’t going to do too much damage on its own, it can be quite possible if you aren’t careful. If you want to avoid paint damage, there are few more things you should know before starting.

First and foremost, NEVER use power washers in close proximity to vehicles especially when you don’t know how to use it safely.

Basically they are meant for outdoor use and using them on cars is extremely dangerous as for a newbie person, it’s very easy for water spray to come into contact with hot exhaust systems, so try, and keep these areas dry at all times.

Also, use low-pressure when possible – anything over 500 PSI is generally unnecessary and will increase water flow speed which can lead to more damage in extreme cases. You also need to be wary of high temperatures – even though most modern cars have clear coatings that are pretty durable, they still can get damaged by high heat.

The last thing you need to worry about is water temperature – never wash your car when it’s below freezing or above 80 degrees Fahrenheit (27 Celsius). These temperatures cause paint cracking and fading respectively, both of which result in expensive repairs down the road.

If you follow these tips closely then chances are good that you won’t run into any issues while washing your vehicle.


Before You Wash:

Make sure you’re washing in a safe location—one with access to running water, for example. You should also have appropriate clothing and eye protection to keep you from injury and damage.

The last thing you want is to damage property or injure yourself while trying to clean it. If you don’t feel comfortable washing a vehicle on your own, consider hiring someone else to do it.

Most body shops will be happy to wash your car (or truck) as long as they’re not already too busy. If that doesn’t work out, ask around at local auto-detailing businesses; they may be able to help out if they aren’t too busy.

In any case, make sure you use an approved soap or detergent so that you don’t cause damage through improper cleaning methods! This16-Piece Kit is best in business.


After The Wash:

Before using a power washer on your vehicle, you should first consider which tool is right for the job. If you are simply cleaning off loose dirt and grime, then an electric model is fine. The Paxcess and this Upright Hand-Carry gadgets are suitable for the job because they already have lower PSI. Affordability also makes them unique from other similar items.

But, if you’re looking to remove stains or paint flecks, then you need high-pressure water that may be too harsh for rubber and plastic car parts like bumpers and side mirrors.

A good rule of thumb is to only use a pressure washer with a tip rated at least 1500 PSI. You also want to avoid getting any part of your body within 10 feet of the nozzle while it’s running as well as never point it at yourself or others.

Finally, keep in mind that applying any chemicals directly onto painted surfaces can cause discoloration over time. Always spray them onto cloth and wipe them down instead.

Also, make sure not to soak your vehicle for more than 30 minutes at a time without giving it time to dry out between applications. Pressure washing can do serious damage if done incorrectly so always take proper precautions before starting any project!
