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.

Best Pressure Washer for Cars & Trucks

Choosing the right pressure washer is a very important piece to the job.

A medium-duty pressure washer is recommended. It can be either gas or electric pressure washer – up to you. If you’re occasionally cleaning your car our recommendation is to use an electric over gas pressure washer, because they typically produce a lower water pressure which is less likely to damage your car’s paint.

Our pick today is the AR Blue Clean (AR383). It’s one of the top rated units (in general), and at 1,900 PSI & 1.5 GPM (gallons per minute) it is strong enough to clean away dirt, but delicate enough to not harm your car.
