How To Pressure Wash Your Car Or Truck (Quicker Than You Ever Thought Possible)

Now that you own a pressure washer you can clean your car or truck with little effort.

Most people think pressure washing is too powerful and will damage the car paint. But there is a safe working procedure that won’t.

This particular method will prevent streaks, prevent damage to fragile bits and yet ensure problem areas like the grill and wheel wells get properly washed.

Here’s 3 Steps To Pressure Wash Your Car Or Truck

If you prefer to just read how to pressure wash your car then here you go. I’ve condensed the video into 3 simple steps.

1. Apply Detergent Bottom Up To Prevent Streaking

Use the 40 degree nozzle to ensure a delicate spray pattern while applying the detergent and removing dirt.
After attaching the garden hose to your pressure washer and filling the detergent tank with car wash detergent you’re good to start up the pressure washer.
Start by holding the spray wand 3 feet from the car moving closer as you need to (this prevents damage) when rinsing the tougher stuck-on bugs and mud or dirt. You’ll probably need to get within 6 inches of the wheel wells as they tend to be the dirtiest, especially in winter and fall.
If required you can use a scrub brush attachment to really grind off the insects from your grill after a long road trip.
Be sure to wear wear protection because debris could get into your eye, especially while blasting in the wheel wells.
Overall, ensure a bottom up approach to prevent the soap from streaking on your car or truck.

2. Leave Detergent For 5 Minutes

Now you’ve done the once over and removed most of the dirt and grime. It’s time to allow the detergent to really clean deep into the surface. Let the suds sit for a few minutes, while intermittently spraying it to keep it wet.

3. Detach Detergent From Flow And Rinse Detergent Top Down To Ensure Best Clean

Ensure you disconnect the detergent because now we’re going to rinse it all away.
Once detached, pull the trigger while pointing away from car or truck to flush it out of the system.
Now using the delicate 40 degree nozzle again spray your car or truck TOP DOWN keeping the lance about 3-4 feet from the car or truck.
Be mindful of fragile parts of your car like the mirrors and any light covers. Just back away a foot further over those parts.
Another tip, if you stickers attached to your car, to prevent peeling them off spray them front on instead of at any angle.

Will Washing My Car with a Heavy-Duty Power Washer Damage It?

1. Use a 25-degree nozzle.

If you keep the end of the pressure washer wand/lance about 1 meter (3 feet and 3 inches) from your car the effective pressure on the car will only be 3x that of a garden hose when compared to the garden hose spray being really close to the car.
That be the right combination of cleaning power and damage avoidance when washing your car.

2. Be extra careful around fragile parts of the car like the mirrors.

Use your instinct and back away even further if you feel you may damage bumper sticker or the mirror or other fragile parts of your car.

3. Learn the double distance half pressure rule

Let’s say you’re using the 25-degree nozzle from 1-foot away with a 3000 PSI pressure washer. The surface that is 1-foot away feels 564 lbs because the 3,000 lbs/in is now spread over a larger area.
If you move 2-feet away that becomes 282 lbs, double the distance half the force.
Keep this in mind when pressure washing in the future!
