Having a routine for your car is always a good practice as it gets dirty on each ride. And I know no one likes to allocate too much effort on the detergent or grease. This is where using a pressure washer sounds legit.
But the question remains. Is it really safe?
I would not say “YES” or “NO”. Both of the answers are true indeed. Let me explain this confusion.
Staying on the Safe Side
Many car detailers around the globe maintain their client’s car by pressure washer. You can find them online. Pressure washers use water pressure for cleaning dirt from car surface or tires.
This only indicates an urge to control the water pressure (which is real simple). This one sentence concludes my saying as “YES”, pressure washing is safe if only you do it the right way.
Not only your car paint or tired that can be damaged by water pressure, your hand or feet can also come in the way.
Each and everything comes with a benefit opponent to disadvantages. And now this is all about pressure washing your car.
A simple straight forward benefit of pressure washing your car is shiny clean surface and tires. People like roaming outdoor with their car or just to cover the distance from home to office. In both cases their car will get dirty. And how much dirt it can get on an off road ride, you know that.
Washing your car with your elbow engaged has been a practice for centuries and still going on. But people love thing that are done without hand touch. This is where the advantages of pressure washers are huge.
Can you point out where and how much dirt or grimes get stuck of your car? The tires and the bottom. Surface dirt or grimes are easy to clean to be honest. Just using your plain, simple garden hose pipe with detergent chemistry you are good to clean the surface of a car. But what about the debris, arrogant grimes on the tires and beneath the car chassis?
All right let’s keep it short and simple. Pressure washers are great for cleaning off any kind of debris and dirt from car surface and also from under the frame. Car tires will shine after a pressure wash.
This can be addictive as it needs less water and energy. Just using a detergent can be enough for cleaning the car.
Like I said you need to do it in the safe way. Too much pressure can definitely damage your car paint or tires. The only disadvantage I found so far.
There are some pressure washers that come with a ‘dirt blaster’ feature which is very effective for cleaning extreme debris and grimes. This is useful for hard surfaces but not for your car exterior. Forgetting to control the dirt blaster level will surely damage the exterior of car.
The damage may not only stick to paint job only but it can also cause dent on the exterior. Both cases, it will take good amount of cash for repair.
Then comes the danger to your surroundings. Assume you are not an expert user or a newbie. Anyways, this can be dangerous for both you and the people around you. Uncontrolled spray of water can damage the property or people.
The glass of your car is fragile and too much pressure is definitely going to damage it causing crack on it. Be careful with it.
Then comes the cost of pressure washing. It includes bill for water (if uncontrolled), electricity or gas. Think you can afford that much?
How Much PSI is Safe for Your Car
The effective way of pressure washing your car is maintaining a safe psi. You do not need a huge pressure for cleaning the car. Car surface is not like concrete surface.
The safest psi falls between 1300 to 1800 psi. Honestly, according to the kind of dirt and debris it’s going to be on the car and under the car more than 1800 psi is not necessary. If you are using a gas pressure washer, which are for pressure more than 2500 psi, never forget to control the pressure within 2000 psi.
Some research indicates holing water pressure form a close range for long time either damages tire wall or weakens them. You want none of them.
Always stick to the safe psi range while washing your car.
Final Thought on Pressure Washing Car
Pressure washing involves few steps if you want it in the safest way. This includes pre-cleaning. With a very slow swirl with the pressure washer wand you get the surface cleaned on the first hand. This will help the detergent work better next.
The one recommendation I can send to you is avoid pressure washing the vintage cars (if any). I see no point of taking the risk for such a master piece collection you have. And for the rest of the cars use pressure washer with care.
One more important fun feature of pressure washer is snow foam cannon. If you love to see your car covered with snow foam then use a pressure washer. Foam cannon is an excellent way of cleaning car surface in the best possible way. Bringing the shine back to new-like is its main feature. Only a dedicated snow foam can eliminate stubborn slug of dirt or grim get off the surface.
Last but not the least, pressure washing is really a fun thing. Once you find the fun in it, nothing will stop you cleaning your car on daily routine. What’s the point of physical pain while you can do it in the fun way?
All I want to recommend you to maintain a safe psi while pressure washing if you love your car and it’s worth it.
